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,
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
used, an LED may be installed at the remote end to
indicate that the power is on.
