The conditions for current equalization are:
Output current is 20 to 90% of the total rated output current
The maximum output current: Rated output current x (number of power supplies) x (0.9 max).
Four units are the maximum allowed.
When the current balance function is used together with the Remote ON/OFF function, connect
together all the (+) RC terminals and connect together all the (–) RC terminals.
3.8 MASTER/SLAVE OPERATION
To adjust all output voltages at the same time by only one V. ADJ. control on the Master Power
Supply (and when using multiple loads),remove the link between the REF to RV terminals on the
Slave Power Supplies: Maintain the links between the (+) S and (+) M terminals and between the
(–) S and (–) M terminals of the Master and Slave units, and connect all the (–)S terminals together,
and connect all the CB terminals together, and all the RV terminals together of the Master and
Slave units. Connect all the (+) output terminals to the (+) load terminal, and all the (–) output ter-
minals to the (–) load terminal.
3.9 PRELIMINARY ELECTRICAL CHECK
Connect an adjustable load across the power supply output terminals, on the center bus bars (on
the front panel, see Figure 9). The load must have a dissipation rating of at least 3000 Watts. Con-
nect a voltmeter and an oscilloscope across the power supply Monitor terminals, (+) M and (–) M,
located on the right side terminal block (on the front panel). The oscilloscope must be isolated from
the source and grounded at the load. Use an isolation transformer between the test equipment and
the AC input power (see Figure 9).
Connect the AC input power to the line, neutral and ground terminals of the left side terminal bar-
rier strip (on the front panel). Turn the unit ON and check the output voltage with and without
load. The output voltage can be adjusted within the published range by using the front panel volt-
age control trimmer.
