PS - PRO II - POWER CONDITIONER / sequencer
POWER STATUS (DELAY) LEDs: One green LED is provided for each of the three delay stages. Each LED lights when power is applied to its corresponding duplex outlet on the rear panel. All three LEDs then remain lit until power is removed. During the power-down delay cycle, each LED goes off as power to its correspond- ing outlet is removed. In addition, the Delay 1 LED flashes if a remote switch (or the stored state) is OFF.
UNSWITCHED OUTLET: This convenient outlet provides power at all times when the PS-PRO II is plugged in and operating under normal power conditions.
CIRCUIT BREAKER: The overall capacity of the PS-PRO II is 20 amps. Should the com-
bined steady-state current drawn by all devices plugged into the unit at any time exceed 20 amps, the circuit breaker will trip, cutting off power to your rack. If this occurs, reduce the load by unplugging one or more units from the PS-PRO II, and reset it. You can reset the circuit breaker by simply pressing the button, which pops out when tripped. However, because it is a thermal type, you may have to wait a few moments after it trips for it to cool down before it will allow you to reset it.
ON/REM/OFF SWITCH: When turned to the ON position, this key lock switch initiates an ON sequence, applying power to the PS-PRO II’s switched outlets. When turned to the OFF position, it begins an OFF sequence. In the REM position, the PS-PRO II will accept on/off commands from a remote switch or switches that

may be connected to the rear panel terminals.
UNSWITCHED OUTLETS: The PS-PRO II rear panel provides clean, filtered power to this pair of unswitched outlets, adjacent to the power cord.
SWITCHED (DELAYED) OUTLETS: The PS-PRO II rear panel provides three pairs of switched outlets, widely spaced to allow use of equipment with plug- in (wall wart) transformers. These switched outlet pairs are labeled Delay 1, Delay 2 and Delay 3. After the front panel switch is thrown to ON, Delay 1 outlets receive power instantly, Delay 2 outlets receive power 1-30 seconds later and Delay 3 outlets receive power 1-30 seconds after Delay 2 outlets are powered.
When thrown to OFF, the sequence is reversed, with Delay 3 losing power instantly, Delay 2 out- lets losing power 1-30 seconds later and Delay 1 outlets losing power 1-30 seconds after Delay 2 outlets are shut down. The delay intervals may be altered with the screwdriver-adjustable Delay Adjust control on the front panel.
TERMINAL STRIP: Allows one or more switches to be connected to turn the PS-PRO II on and off from a remote location. Two, and sometimes three, wires are needed to install a remote switch (see “Maintained Mode”, page 6.) If a four-conductor cable is used, an LED may be installed at the remote end to indicate that the
power is on.
