Warranty Information
Contact your dealer or distributor for information regarding repair work or fuse replacement.
Operation Summary
Power On/Off: Use the POWER switch on the front panel. The OUTPUT switch controls power to the load.
Setting Voltage/Current: Use the VOLTAGE control for voltage and the CURRENT control for current. The LIM key allows checking set values.
Over-Voltage Protection (OVP): Set OVP voltage using the OVP control and check with the OVP key. If OVP is exceeded, the output turns off and the OVP LED lights up.
Remote Control: Switches on the rear panel allow remote control of the main relay and output on/off, as well as voltage and current control via external voltage or resistors.
Monitoring: Voltage and current can be monitored via analog output signals on the rear panel. Alarm and status signals are also available.
Resetting Protection: Over-voltage and alarm conditions can be reset via specific procedures involving the POWER switch and external control signals.
