unswitched outlets. We suggest keeping the front
panel unswitched outlet free for equipment that
is only in use temporarily.
The overall capacity of the PS-8R II is 15 amps.
This refers to the combined steady-state current
drawn by all devices plugged into all of its nine
outlets. If this combined current level exceeds
15 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-8R II. Then push the button on
the circuit breaker (on the front panel) down and
in to reset it.
Although 15 amps is an absolute limit, the PS-8R
II's power sequencing capability will allow you to
come as close as possible to using the full 15
amps, because the risk of tripping the breaker
is greatly reduced. This is because the PS-8R II
handles large but temporary inrush currents in
stages, rather than simultaneously, allowing each
stage to settle to its steady-state current draw
before the next stage is powered.
ADjuSTING THE DELAy INTERVAL
The delay interval (the time between the turn-on
or turn-off of outlets 1 and 2, or 2 and 3 — not
1 and 3) is factory preset at approximately 5
seconds. It is possible to lengthen or shorten the
3
delay interval by making an internal adjustment
to the PS-8R II. However, due to the risk of
electric shock, this procedure should only be
done by a qualified technician.
unplug the PS-8R II and remove its top cover by
unscrewing the 10 top panel screws that secure it.
The delay adjustment is Trimpot VR1, located on
the printed circuit board near the front left corner.
It is the only trimpot on the board. It is equipped
with a thumbwheel for easy adjustment. The
range of adjustment of the delay interval is from
a minimum of about 1 second to a maximum of
about 7 seconds.
220/240V VERSION
(WITh "E" SuFFIx ONly)
The model PS-8R II E is intended for use in
countries with nominal 220 to 240 volt AC lines.
It is identical to the PS-8R II except the rear panel
outlets are the internationally-accepted IEC-320
connectors. It is rated at 10 amps.
