Furman ASD-120
AC Sequenced Power Distributor, 120A

OUR PART #  ASD-120-2.0


Furman's ASD-120 AC sequenced power distributor is an extremely compact, low cost rackmount power distribution system that is well-suited for touring PA systems, touring musical and theatrical acts, mobile recording facilities, on-location film and video shoots, etc. - any situation where AC power must be distributed to multiple circuits and a hard-wired, built-in system is missing, inadequate, or impractical. Use of a power distributor is cost-effective, both in terms of the convenience it offers and the elimination of bulky and expensive parallel feeds and related connectors.

The ASD-120 allows you to power up its six circuits in a sequenced fashion. The sequence is reversed for power down. The delay interval is user-adjustable via an internal trimpot.

The ASD-120's 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 that 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. A locking switch with a removable key is provided for maximum security.

Since the sequence control signals are also available on the rear panel, one or more ASD-120's may be installed in remote locations and operated via low-voltage control wiring. The sequence control signals can also drive 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.

The ASD-120 can handle up to 120A of incoming power, distributing it to (6) 20A, 120V circuits. Each circuit has a front panel status indicator that lights up when it is turned on, and a 20A duplex outlet on the rear panel.

The ASD-120's design 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. Complete instructions accompanying the unit guide the user through the process of selecting and terminating the supply cable.
