The PS-PRO is a power sequencer, meaning it is ca- pable of powering a rack full of equipment in three steps separated by timed delays. It is useful whenev- er 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 can cause circuit breakers to trip even though the steady-state currents are not excessive. Power sequencing is particularly suited to applications where large installations must be switched by inexperienced personnel.
The PS-PRO is controlled by a front panel key-op- erated switch to provide security from non-autho- rized users tampering with the system. The switch has three positions: OFF, ON, and REM, allowing for local or remote control. With remote control, one or more PS-PRO’s may be installed in remote locations with on/off control and LED monitoring via low-voltage control wires.
Besides its power sequencing capabilities, the PS- PRO contains many other conditioning and protec- tion features. Both aspects of its functioning will be
discussed in the next sections.
