Furman ASD-120 2.0 6 Circuit Sequencing Distribution, (6) 20A 120V circuits, 240V or 3-Phase 208V input

Updated for easier installation and operation, the ASD-120 2.0 is a compact rack-mount power distribution system for use where AC power must be distributed to multiple circuits and there is no hard-wired, built-in system. , The ASD-120 2.0 AC Sequenced Power Distributor updates the ASD-120, optimized for easier installation and operation. The ASD-120 2.0 is an extremely compact, low cost rackmount power distribution system ideal 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. , The ASD-120 2.0 allows you to power up and its six circuits in a sequenced fashion. The sequence is reversed for power down. The delay interval is user-adjustable via an internal trimpot. ,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 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.
