in load will be supplied by the second unit up to its current limit setting. Regu
lation, therefore, will be the sum of the regulations of the units plus the dif
ference in the voltage settings.

LOAD
For remote sensing, connect both unit + and - terminals directly to the load
instead of output terminal board. OBSERVE POLARITY. Forward diode types listed
in Table 3-3 for series connection will be adequate. Heatsinking is also neces
sary.

Direct Parallel Connections
Master /Slave Paralleling ( Figure 3-9)
To connect two units in parallel, proceed as follows:
NOTE.
Up to three slave units may be added by ex
tending this procedure.
1.
With no load applied, set master unit POWER switch to ON, and adjust
voltage to desired system output (plus total load lead drop unless in
the remote sensing mode). Set unit power to OFF.
2.
Connect load leads from both units to the load. If possible, use load
leads of approximately equal length. Observe Polarity.
3.
Disconnect link between · terminals 7 and 8 on slave unit.
Set slave
voltage controls fully clockwise. Connect a wire between terminal
8
of
the slave unit and terminal
10
of the master unit.
