4.
Set master unit POWER switch to ON, and then set the slave unit POW
ER switch to on.
5. . Adjust control R53 (on Control PCB) to balance the output currents be
tween the paralleled units.
Note that the units should be adjusted for equal output currents using
the heaviest load (i.e. , with both units operating near full load rating).

Forward diode types listed in Table 3-3 for series connection will be adequate.
Heatsinking is also necessary.

SERIES OPERATION
Direct Series Connections (Figure 3-10)
DCR-B supplies may be directly series connected up to a total output of 200 Vdc
(150/300/600 volt models, two in series). System regulation is the sum of the
regulations of all units.
The procedure is outlined for connecting two units in series. Additional units
may be connected by repeating the procedure for each.
Operation
NOTE
Series connected units may be adapted to resist-
-ance or signal programming.
Be sure pro-
gramming device is isolated from ground suffi
ciently to withstand maximum series operating
potential.
