PS - PRO HT - POWER CONDITIONER/SEQUENCER

OFF sequence. In the REM position, the PS-PRO HT will accept on/oﬀ commands from a remote switch or switches that may be connected to the rear panel terminals.

CIRCUIT BREAKER: The overall capacity of the PS- PRO HT is 20 amps. If the combined steady-state current drawn by all devices plugged into all of its nine outlets level exceeds 20 amps at any time, the circuit breaker will trip, cutting oﬀ power to your rack. If this occurs, you must reduce the load by unplugging one or more units from the PS-PRO

HT, and reset it. You can reset the circuit breaker by simply pressing in 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.

UNSWITCHED OUTLETS: The PS-PRO HT rear panel provides clean, ﬁltered power to this pair of un- switched outlets, adjacent to the power cord.

SWITCHED (DELAYED) OUTLETS: The PS-PRO HT

rear panel provides three pairs of switched outlets,	indicate that the power is on.
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 re-
ceive 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 outlets 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 HT on and oﬀ from a
remote location. Two, and sometimes three, wires
are needed to install a remote switch (see “Main-
tained Mode”, page 6.) If a four-conductor cable is	6
used, an LED may be installed at the remote end to	6
