Each power supply is programmable locally from the front panel or remotely via a rear-panel
analog control port. Operational features include:
■ Constant voltage (CV) or constant current (CC) output over the rated output range.
■ Built-in overvoltage (OV), overcurrent (OC), and overtemperature (OT) protection.
■ Automatic turn-on selftest
■ Pushbutton nonvolatile storage and recall of up to 5 operating states
■ Local or remote sensing of output voltage
■ Auto-parallel operation for increased total current
m
Series operation for increased total voltage
■ Analog input for remote programming of voltage and current
■ Voltage output for external monitoring of output current
■ User calibration from the front panel
Front Panel Programming
The front panel has both rotary (RPG) and keypad controls for setting the output voltage
and current. The panel display provides digital readouts of the output voltage and current.
Other front patnel controls permit:
■ Enabling or disabling the output
■ Setting the overvoltage protection (OVP) trip voltage
m
Enabling or disabling the overcurrent protection (OCP) feature
■ Saving and recalling operating states
■ Calibrating thepower supply
Analog Programming
The power supply has an analog port for remote programming. The output voltage and/or
current of the power supply may be controlled by d-c programming voltages applied to this
port. The port also provides a monitor output that supplies a d-c voltage proportional to the
output current.
