MULTIPLE-SUPPLY OPERATION
Normal parallel and auto-parallel operation provides increased out-
put current while normal series and auto-series provides increased
output volta

e. Auto-trackin

NORMAL PARALLEL OPERATION
Two or more power supplies bein
g
capable of CV/CC automatic
cross over operation can be connected in parallel to obtain a total
output current
g
reater than that available from one power suppl
y
.
The total output current is the sum of the output currents of the
individual power supplies. The output of each power suppl
y
can
be set separatel
y
. The output volta
g
e controls of one power sup-
pl
y
should be set to the desired output volta
g
e; the other power
suppl
y
should be set for a sli
g
htl
y
hi
g
her output volta
g
e. The sup-
pl
y
with the hi
g
her output volta
g
e settin
g
will deliver its constant
current output, and drop its output volta
g
e until it equals the out-
put of the other suppl
y
, and the other suppl
y
will remain in con-
stant volta
g
e operation and onl
y
deliver that fraction of its rated
output current which is necessar
y
to fulfill the total load demand.

ure 8. Normal Parallel Operation of Two Supplies
AUTO-PARALLEL OPERATION
Auto-parallel operation permits equal current sharin
g
under all load
conditions, and allows complete control of output current from one
master suppl
y
. The control unit is called the master; the controlled
units are called slaves. Normall
y
, onl
y
supplies havin
g
the same
model number should be connected for auto-parallel operation,
since the supplies must have the same volta
g
e drop across the cur-
rent monitorin
g
resistor at full current ratin
g
. The output current of
each slave is approximatel
y
equal to the master's. Fi
