CPS250 User Manual

Reference
This section of the manual includes examples of how to use the
CPS250 Triple Output Power Supply. The number of possible
applications is extensive, so only a few examples are given.
CAUTION. Heat buildup may occur on the rear-panel heat sink during
operation. To prevent equipment damage, ensure that the power
supply has adequate air space for heat dissipation. Do not place
hands or other objects on the heat sink during or after extended
operation.
Independent Mode Applications
When in INDEPENDENT mode, any one output of each supply may
be connected to any one terminal of another supply or to ground.
Variable supplies are independently controlled by front panel voltage
and current controls. Ground reference is recommended for safety.
There are two types of independent mode operation:
H Series Operation. A and B supplies (outputs) can be set to give
0 V to 40 V output with the A/B OUTPUTS switch.
H Parallel Operation. A and B supplies (outputs) may be set to
parallel operation with the A/B OUTPUTS switch. A and B
supplies may be operated in parallel to increase current. Refer to
Parallel Tracking on page 14.
Independent Floating
Figure 3 on page 8 shows each of the three power supply outputs
connected to separate loads. In this example the A/B OUTPUTS
switch is set to INDEPENDENT. The green coded A VOLTAGE and
A CURRENT controls set the level of output A. The brown coded
controls set the level for output B. The three outputs are electrically
independent. The V and mA meters read A or B output values
(selected with the A/B meter switch).
