CPS250 User Manual
To configure the power supply for independent floating, do the
following:
1. With the CPS250 Triple Output Power Supply on and the outputs
disconnected from loads, set the A and B VOLTAGE controls to
the values needed (read on the V meter). Set the A and B
CURRENT controls to midrange.
2. Turn POWER to OFF, and connect the load(s).
3. Turn POWER to ON, and readjust voltages if necessary.
Load 1
5 V
Zero to 2 A
Load 2
Zero to 20 V
Zero to 0.5 A
Load 3
Zero to 20 V
Zero to 0.5 A

CAUTION. To prevent damage to the equipment when using any
ground-referenced output configuration from the CPS250, the circuit
or equipment being powered must be isolated from the CPS250’s line
voltage power source.
Any one of each pair of output terminals, positive (+) or negative (–),
may be connected to ground in any combination. Table 1 shows
many of the possible voltage combinations using the chassis ground
as a reference.
