2.2 BASIC OPERATION

The programmable power supplies offer a combination of programming
capabilities and a variety of dc output power ratings that make them ideal for
power systems applications. The +V and +S as well as the -V and -S terminals
have been connected to each other at the factory.

channel
Each output channel can be programmed to the desired dc voltage or dc current
(output function). Self-contained measurement and readback capability eliminate
the need for using a separate multimeter to externally meter the output channel.
The readback voltage and current of the selected output channel can be
monitored on the front panel display (measure function). Protective circuitry within
the power supply limits or turns off an output channel when an abnormal condition
occurs. The following protection features have been implemented:
• OVERVOLTAGE and OVERCURRENT
• UNREGULATED OUTPUT
• OVERTEMPERATURE
• OUT OF SENSE CAPABILITY
• COUPLED PROTECTION (of output channels)
Each output channel can operate as a constant voltage source (CV mode), or
as a constant current source or current sink (PM283x only) (CC mode):
• As a constant voltage source the output voltage remains constant, while
the output current changes due to fluctuations of the load.
• As a constant current source the output current remains constant, while
the output voltage changes due to fluctuations of the load.
