The conditions for current equalization are:
Output current is 20 to 90% of the total rated output current
Equalization Rate: The output current range in each switching Power Supply under condition 1 com-
plies with the following:
Two 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 PRELIMINARY ELECTRICAL CHECK
Connect an adjustable load across the power supply output terminals, on the center (+) and (–)
bus bars (on the front panel, see Figure 9). The load must have a dissipation rating of at least
1500 Watts. Connect 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.
