III — OPERATION
When output voltage is available, the green LED is on. The
Output Voltage Adjust trimmer (see Figure 3) allows adjust-
ment of the output voltage.
REMOTE ON-OFF CONTROL:
When remote ON/OFF
is not in use, ±RC terminals must be shorted (use shorting
link supplied) for unit to operate. Remove short across ±RC
and apply "high," 2.4V to 24V (or open), across ±RC to turn
unit OFF (Fan Off). Apply "low," 0.0V to 0.4V (or closed)
across ±RC to turn unit ON. Source current is 1.6mA maxi-
mum at low level, and sink current is 1.0 mA maximum at
high level. The ±RC terminals are isolated from the a-c
input terminal and the DC output terminals.
REMOTE VOLTAGE PROGRAMMING:
In addition
to the integral trimmer, output voltage can be also be
adjusted via an external variable resistance or external
variable d-c voltage. Refer to the Operator’s Manuals listed
on page 1 for details.
PARALLEL OR SERIES OPERATION:
Power Sup-
plies can be connected in parallel (with or without N+1
redundancy) for increased current or in series for increased
voltage. Refer to Operator’s Manual listed on page 1 for
details.
PRELIMINARY ELECTRICAL CHECK
To verify
power supply functionality, refer to Operator’s Manual listed
on page 1.
