Furman PS-8R

The Furman PS-8R Power Sequencer is needed whenever various kinds of equipment must be powered up or down in groups, rather than all simultaneously. In audio systems, sequenced powering is often necessary to allow turn-on transients from low level amplifiers and processors to settle down before any power amps are turned on, because simultaneous powering would result in a loud, annoying, and potentially destructive “pop” reaching the speakers. And in any large system whose components present an inductive load to the AC line (including electric motors, power supplies, and power amplifiers of all kinds), sequenced powering can avoid excessive inrush currents that cause circuit breakers to trip even though the steady-state currents are not excessive.

Using the PS-8R is a simple and inexpensive way to apply and remove power in a controlled, repeatable, foolproof 3-step sequence. It is ideal when large installations must be switched by inexperienced personnel.

The PS-8R provides three outlet pairs labeled Delay 1, Delay 2, and Delay 3, that receive power almost immediately, 5 and 10 seconds respectively after the front panel switch is thrown to “ ON.” When thrown to “OFF,” the sequence is reversed, with Delay 3 losing power almost immediately, Delay 2 after 5 seconds, and Delay 1 after 10 seconds. The delay intervals are preset at these durations, but may be altered by means of an internal trimpot adjustment. In addition to the delayed outlets, a single front panel outlet and a rear panel pair are unswitched. All rear panel outlets are standard 120V, 15A duplex types; isolated ground “ super spec” outlets may be substituted at additional cost. The PS-8R offers all basic power conditioning features besides its sequencing capability. It provides varistor spike and surge protection across all three modes, as well as a sophisticated EMI/RFI filter for blocking radio frequency line noise. Clean, filtered power is provided at all 9 outlets, even the unswitched ones.

The PS-8R also assists in analyzing any faults that may occur in the AC mains wiring. Two green and one red neon indicators light in a specific pattern for normal wiring and in different patterns for various faults. When the AC wiring is correct, both green indicators will be lit. If a fault is present, a chart next to the indicators will identify its exact nature.

The Power Sequencer provides three delayed outlet pairs with a delay time interval of 5 seconds, controlled by a front panel master switch. The on-off sequence shall be initiated either locally or with a momentary or maintained contact switch at a remote location, connected with Class 1 wiring. Outlet switching shall be by means of relays with silver cadmium oxide contacts rated at least 30 amps for inductive or resistive loads. Relay life expectancy shall be at least 100,000 operations at rated load. Printed circuit boards shall be 3 oz. copper FR4 glass epoxy. Indicator lights shall be provided to signal when power is available at each of the delayed outlets. All outlets shall be rated 15 amps. Unswitched outlets shall be provided both in front and rear. Spikes at all outlets shall be clamped to no more than 250 V peak (line to neutral, line to ground, or neutral to ground.) Response time shall not exceed 1 nanosecond. The unit shall absorb a surge current of up to 5000 amperes for 10 ms without damage. RF noise attenuation shall exceed 40 dB (transverse mode) and 60 dB (common mode) from 1 to 200 MHz. A 15 amp circuit breaker shall be provided, and the AC cord shall be 14 ga. and ten feet long.

Furman PowerLink Remote Sequencer

The PowerLink is a compact, low-cost rackmount Remote Sequencer that provides timing and switching for up to six power control devices, turning them on and off in a preset sequence. The power-down sequence is opposite to the power-up sequence - the last device to be turned on will be the first turned off, etc. The delay interval between the turn-on or turn-off of each device and the next device in sequence is user-adjustable from 0.2 to 10 seconds, via an internal trimpot.

A PowerLink is intended to work with a group of relay-controlled power outlets such as Furman MiniPorts, to create a very flexible power control system that can expand to handle as many circuits carrying as much current as needed.

An on or off sequence can be initiated from the PowerLink itself, using the built-in locking key switch, or, if the key switch is set to enable Remote operation, by one or more momentary or maintained-action switches in distant locations.

The outputs of the PowerLink are low power relay contacts, accessible via rear-panel screw terminal strips. Outputs may be configured to be normally-closed or normally-open by positioning internal "suitcase" jumpers. All input and output commons are electrically isolated to avoid the creation of ground loops.

Power sequencing is needed whenever various kinds of equipment must be powered up or down in groups, rather than all simultaneously. In audio systems, sequenced powering is often necessary to allow turn-on transients from low level preamplifiers and processors to settle down before any power amps are turned on. This is because simultaneous powering can result in a loud, annoying, and potentially destructive "pop" reaching the speakers. Also, In any large system whose components present an inductive load to the AC line (including electric motors, power supplies, and power amplifiers of all kinds), sequenced powering can avoid excessive inrush currents that can cause circuit breakers to trip even though the steady-state currents are not excessive.

The user has complete control of each of the PowerLink's outputs. A three-position front panel switch for each control output allows that output to be included in the sequence, or permits overriding the sequence to switch that output on or off independently of the sequence timing. Indicator LED's light up to show when each output is in the "on" state.

While the PowerLink is ideal for controlling MiniPorts, it can also control Furman PowerPorts, PS-PRO or PS-8R Power Sequencers, ASD-120 Sequenced Power Distros, or any other devices that need to be switched when a particular time delay has elapsed. A PowerLink can even control one or more other remotely-located PowerLinks, providing complete power sequencing control for even the very largest systems.

Furman PowerPort Remote AC Power Controller

PowerPorts offer the same renowned RFI/EMI and spike/surge protection as Furman's top-of-the-line PRO Series rackmount power conditioners. A PowerPort can safely absorb up to a whopping 11,000 amperes of spike/surge current in any mode (hot-neutral, neutral-ground, or hot-ground), using a unique array of protection devices including MOV's, gas discharge tubes, high voltage inductors and capacitors, and fast-blow fuses. It also provides over 60 dB of common-mode attenuation in the 1-200 MHz RF band.

An additional feature, Extreme Voltage Shutdown, fights a hazard particularly common in the entertainment industry: wiring faults -- for example, accidental connection to 220V. It senses voltages that are so high or low that operation would be impossible (under 80V or over 140V) and shuts the power down before damage can occur. An "Extreme Voltage" LED blinks a red alert when an abnormal voltage causes shutdown. Other status indicators ("Protection OK" and "Ground OK") monitor the integrity of the protection devices and grounding, and report if the protection is compromised. A "Mains OK" LED glows steady for normal input voltage and blinks a warning for marginal but not extreme voltages (80-90V or 130-140V).

As a power sequencer, PowerPort has independent turn-on and turn-off delays, with simple daisy chaining for remote switching of single or an unlimited number of multiple units. Control wiring can be up to five miles in length without performance degradation, based on using 24 AWG. The PowerPort has two modes of operation: maintained and momentary. These terms refer to the type of switch that is attached to the remote terminals, and determine the functionality of the unit. The mode may be easily changed by moving a suitcase jumper on the circuit board.

Furman MiniPort-15 Power Relay & MiniPort-20 Power Relay

The MiniPort-15 Power Relay is a UL/CUL listed, 15 amp, relay switched 120 VAC outlet, with a terminal strip that allows remote control via safe, inexpensive, low voltage Class 2 wiring. Also available is the MiniPort-20, which is functionally identical except for its 20 amp rating. Both models include an internal 12 VDC supply, and can be controlled from a remote location with maintained or momentary contact switches.

Multiple MiniPorts may be connected together so that all are controlled by a single switch closure, and may be linked so that all turn on simultaneously or one by one, in a delayed sequence. If delayed, the delay interval between the turn-on of one MiniPort and the next is approximately 3 seconds. (Delayed turn-on is useful in avoiding large inrush currents that can trip house circuit breakers, that would otherwise occur if all amps were turned on simultaneously.) Turn-off always occurs simultaneously, however.

A Furman PowerLink can also be used to control MiniPort(s). In this use, the MiniPort(s) areconnected to terminals on the PowerLink, which provide the necessary control functions. MiniPorts are similarly compatible with the Furman PowerPort and ASD-120 Sequenced Power Distro. With the addition of a PS-REL AC Relay to provide control, a MiniPort can be used to extend the capacity of any other Furman power product — or, for that matter, any product with a switched outlet, such as a receiver/ amp controlled with a wireless remote. When used in this manner, the MiniPort is switched on or off when the outlet that the PS-REL is plugged into goes on or off.

Both the MiniPort-15 and the MiniPort-20 come equipped with two knockout holes for permanent installation with 1/2" conduit — one on the top surface, the other on the bottom. Use of the bottom knockout hole requires removing the AC cord. According to the National Electrical Code, 1/2" conduit can accommodate up to five 20 amp circuits using ten THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements.

MiniPorts are housed in rugged steel enclosures and come equipped with a heavy duty, 10 foot AC cord. The MiniPort-15 is fused; the MiniPort-20 is equipped with a precision magnetic circuit breaker. The MiniPort-20 and MiniPort-15 are UL and CUL (Canadian) listed. Note: Because of its UL listed 20 amp rating, the MiniPort-20 uses a 20 amp AC plug with perpendicular (not parallel) blades. If in doubt regarding your installation, please consult an electrician or call the factory. The MiniPort-20 is an upgrade of an earlier Furman MiniPort. The primary differences are the ability to use momentary switches, the delayed turn-on option, and the additional knockout holes.

Furman MiniPort-20Q Power Relay

The Miniport-20Q (20amp) provides a pair of remotely activated, relay-controlled outlets which are both set up for mounting in any standard electrical Quad Box, either directly or with a "mud ring" attached.

Due to the space limitations of a Quad Box, the "Q" Miniport models have a smaller feature set than the Miniport-15 and Miniport-20. The MP-20Q has no internal power supply; a maintained 10-30VDC supply capable of supplying 10 mA is required to turn on the outlets. This can be supplied by a Furman PowerLink, ASD-120 or PS-8R (with a simple internal modification to the PS-8R). UL, C-UL pending.

Datasheet

Furman MiniPort-30 Power Relay

The Miniport-30 Power Relay is a 30 amp, contactor switched 120 VAC outlet, with a terminal strip that allows remote control via safe, inexpensive, low voltage Class 2 wiring. The Miniport-30 provides a twistlock inlet and outlet, and is housed in a heavy duty steel, 8" x 8" x 4" junction box.

This model includes an internal 12 VDC supply, and can be controlled from a remote location by using the Furman PowerLink Remote AC Power Sequence Controller, the ASD-120 Sequenced Power Distro, or for simpler jobs, the Furman RS-1 or RS-2 Remote System Control panels. The RS-1 provides a maintained key switch; the RS-2 has a momentary switch.

Multiple Miniports have their control wiring paralleled so that all are controlled by a single switch closure, and may be linked so that all turn on simultaneously or one by one, in a delayed sequence. If delayed operation is chosen, the delay interval between the turn-on of one Miniport and the next is approximately 3 seconds. (Delayed turn-on is useful in avoiding large inrush currents that can trip house circuit breakers, that would otherwise occur if all amps were turned on simultaneously.) Turn-off always occurs simultaneously.

All four sides of the enclosure have multiple knockouts to accommodate every installation, with 3/4" conduit- one on the top surface, the other on the bottom. According to the National Electrical Code, 3/4" conduit can accommodate up to eight 20 amp circuits using sixteen THWN 12 gauge stranded wires; however, local codes should be checked for exact requirements.

With the addition of a Furman PS-REL AC Relay to provide control, a Miniport can be used to extend the capacity of any other product that has a switched outlet, such as a receiver/amp that is then controlled with a wireless remote. When used in this manner, the Miniport is switched on or off when the outlet that the PS-REL is plugged into goes on or off.

Furman RS-1/RS-2 Remote Control Panels

The RS-1 and RS-2 remote system control panels provide a simple way to control AC equipment from one or more locations, using only inexpensive low-voltage wiring.

The panels can be easily installed in a single gang switchbox with a minimumdepth of 1.5". Features common to both models include a locking key switch and a "System On" indicator LED. THe RS-2 includes a momentary "Start ON/OFF Sequence" push-button, while the RS-1 is a maintained contact version. The rear of the panels have a circuit board with a full size barrier strip for field wiring connections.

The RS-1 and RS-2 can be used to control the Furman ASD-120 sequenced power distributor, the PowerLink, PowerPort, Remote AC Controller, the MiniPort Power Relay series, or the PS-8R, PS-8R II or PS-PRO II Power Sequencers, as well as other equipment that needs a switch contact at a remote location.
