Dual Power Supply Used in Parallel Mode
1. Set the tracking switches 11 & 12 to the IN position. The master and
slave outputs will now be in parallel mode. Adjust control 3 to the
desired output voltage and the voltage of the master and slave outputs
should change identically.
2. In Parallel Mode, the output current adjusted by the master output
current adjustment control knob (4) and the slave control (6) has no
effect. The maximum output current is the sum of the master and slave
output currents.
3. In Parallel Mode, terminals 13 & 16 and 15 & 18 should be connected
respectively with thick conductive wire to prevent damage to the unit in
the event of an overload.
CAUTION:
• In the event of a short circuit at the output, the current will limit at the
value set by the current controls. However, the unit should be turned
OFF and the short circuit removed before continuing use.
• The unit must be unplugged before servicing. Servicing should be
performed by a qualified repairperson with knowledge in electrical
hazards.
Dual Power Supply Used in Series Mode
1. Set the tracking switch 12 to the IN position and tracking switch 11 to
the OUT position. Adjust the master and slave output current
adjustment control knobs (4 & 6) clockwise to the maximum position.
Adjust controls 3 and 5 to the desired output voltage. The voltage of the
master output should be tracked by the slave output. The highest output
voltage is the sum of the value of both master and slave outputs when
connecting the load to terminals 13 & 18.
2. In Series Mode, the current adjustment is independent. If the slave
control (6) is not at the maximum position but at a current limiting
position (CC LED lit), then the voltage of the slave output will not track
the master output.
3. In Series Mode, terminals 15 & 16 should be connected together with
a thick conductive wire to prevent damage to the unit in the event of an
overload.
4. In Series Mode, remove any connection between the master or slave
negative terminals and the ground connection terminals. Otherwise, it
is possible to short-circuit the slave output.
