Description
IEC type appliance inlet.
EIA/TIA-568A type connector, used for connecting power
supply to RS232 or RS485 port of computer for remote
control purposes. When using several power supply units
in a power system, the first unit Remote-in is connected to
the computer and the remaining units are chained,
Remote-In to Remote-Out.
EIA/TIA-568 type connector, used for chaining power
supplies to form a serial communication bus.
Connector containing control and signal lines for external
(remote) control of the power supply. +/- Sense, On/Off,
Output voltage and current programming by external
resistor and Output voltage and current programming by
external voltage and Output Good signal.
Bus bars for output connection. Use M6 or 1/4” screws for
load wire connections.
M4 thread for grounding either the positive or negative
output.
Male connector , PSC 1.5/3-M-PE , Phoenix.

TURN-ON CHECKOUT PROCEDURE
4.3.1 General
4.3.2 Prior to operation
4.3.3 Constant Voltage check
The following procedure ensures that the power supply is operational and may be used as a basic
incoming inspection check.
Check that the Rear panel external control receptacle is properly inserted into the connector and the
wires are connected as shown in Fig: 3-6. Connect the unit to an AC source as described in paragraph
3.6. Connect a DVM to the output terminals.
Turn-on the power supply. Turn on the output by pressing OUT pushbutton so the OUT LED illuminates.
Momentarily press V/A pushbutton, until the V LED illuminates and the VOLTS display shows FA_V.
The AMPS display will show the last setting of the output voltage. Rotate the Adjust knob at the front
panel and check that the output voltage can be varied throughout the entire range. Check that the
AMPS display shows the correct output voltage (within the display specifications). Momentarily press
V/A pushbutton again, so the A LED illuminates and the VOLTS display shows FA_A. The AMP display
will show the last setting of the output current. Rotate the Adjust knob and check that the AMP display
varies. Set the AMP display to the rated output current.
