The Furman ASD-120 AC Sequenced Power Distro is an extremely compact, low-cost rackmount power-distribution system that is ideal for mobile PA systems, touring musical and theatrical acts, mobile recording facilities, on-location film and video shoots, and more. It is ideal for any situation where AC power must be distributed to multiple circuits and a hard-wired, built-in system is missing, inadequate, or impractical.
The ASD-120 allows for six circuits to be powered up in a sequenced fashion, and the sequence is reversed for power down. The delay interval is user-adjustable via an internal trim pot. The front panel provides a three-position switch for each circuit that allows each circuit to be part of the power-up/down sequence, or to remain on or off apart from the sequence. An LED indicates when either the power-up or power-down sequence is in progress. The sequence can be initiated with either momentary or maintained switches, locally or remotely. A duplex outlet is provided for each delay step.The distributor has a low-voltage lockout that prevents the unit from sequencing on when the line voltage is too low.
The ASD-120 can handle up to 120 amps of incoming power, distributing it to six 20-amp, 120V circuits. Each circuit has a front-panel status indicator that lights up when it is turned on, and a 20-amp duplex outlet on the rear panel.
Since the sequence control signals are also available on the rear panel, one or more ASD-120s may be installed in remote locations and operated via low-voltage control wiring. The sequence-control signals can also drive PowerPorts, MiniPorts, PS-PRO and PS-8-R Power Sequencers, or any other circuits that need to know when their particular time delay has elapsed. Using one or more ASD-120's can provide the capability of controlling power and power sequencing for an entire system.
This unit incorporates four oversized busses, allowing wiring for 120V or 240V single-phase, or 208V three-phase power. A strain relief clamp is provided that can accommodate a cable or wire bundle up to 1.5" in diameter. Cable termination is a simple process of breaking out and stripping the individual conductors and connecting them with set screws, and then tightening the strain relief clamp.
Spike-Clamping Voltage: TVSS rating 400V peak, L-N, N-G, L-G (tested to UL 1449)
Six widely spaced duplex outlets on rear panel
The REMOTE function can be set using 3 dip (12V ON, 12V OFF, GND ON, MAINTAINED/MONMENTARY) switches under the front-panel security cover.
The trim pot and the 3 dip switches (1M, 2M, 4M) settings are on the front panel under the security cover. The maximum time is 7 minutes per step.
A locking switch with a removable key is provided for maximum security.
Steel chassis, zinc-chromate plating; .125" brushed and black anodized-aluminum front panel.
