2.2.2 DUAL POWER SUPPY USED IN SERIES MODE
2.2.2.1 Select switch 14 to the in positions and switch 13 to the out position. Adjust controls 6&8
clockwise to the maximum position. Adjust control 5 (master voltage control) 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 15&20.
2.2.2.2 In series mode, current adjustment is independent. If control 8 is not at the maximal
position, but at a current limiting position then the voltage of the slave output will not track the
master output.
2.2.2.3 In series mode, terminals 17&18 should be connected together with a thick conductive
wire to prevent damage to the unit in the event of an overload.
2.2.2.4 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.
2.2.3 DUAL POWER SUPPLY USED IN PARALLEL MODE.
2.2.3.1 Select switches 13&14 to the in position, the master and slave outputs will now be in
parallel mode. Adjust control 5 to the desired output voltage and the voltage of
the master and slave outputs should change identically.
2.2.3.2 In parallel mode, the output current is adjusted by the master control 6 and slave control
8 has no effect. The maximum output current is the sum of the master and slave output currents.
2.2.3.3 In parallel mode, terminals 15&18, 17&20 should be connected respectively with thick
