Each individual circuit can be sequentially soft-started with a user-programmed delay, eliminating the large inrush and earth leakage currents associated with the sudden start-up of a large array of equipment. Likewise, multiple APS units can be cascaded so that the next sequenced unit will not start its automatic start-up sequence until the previous unit has finished.

Nuisance circuit breaker tripping, generally caused by large inrush start-up currents and excessive earth leakage, is overcome by the APS by switching on the relay as the mains voltage passes through the zero point of the sine wave, thus providing a pseudo soft-start.

When a DMX signal level is detected, the APS will commence start-up procedure, regardless of actual DMX levels. When the DMX signal ceases, the APS will commence shut-down after a user-programmed time. Great feature for venues where someone forgets to shut down the power when closing for the night.

Programmable input supply overvoltage and undervoltage trips for each phase to protect loads against out-of-spec mains and the possibility of dropped Neutrals; Neutral disconnect MCBs (RCBOs) with inbuilt 30Ma RCD to meet the highest level of safety and electrical compliance.

In addition to the front panel set-up for stand-alone mode, the APS can be remotely controlled via DMX512 signals, GPI voltage free contact closure for remote triggering and Remote Device Management (RDM) to switch units off and on.

Choice of circuit output capacity, number of circuits per unit, output connector styles and 3-phase or single-phase operation. The unit can be 19" rack-mounted for portable use or wall-mounted for permanent installations – versatility plus for any situation!
