Operation
Introduction
The device is a highly accurate, DC-regulated power supply with an adjustable
output. This output can be used for constant voltage (C.V.) and constant
current (C.C.).
The output voltage can be adjusted between 0 V and 50 V when the device is in
the constant voltage mode or C.V.-mode. The current-limiting point (max. ± 5
A) can also be set arbitrarily in this mode.
The output current can be adjusted continuously between 0 and 5 A in the
constant current mode.
The output current and voltage are indicated through LED displays.
Using the device as a C.V. source
- Switch on the device.
- Turn the current adjustment knob fully clockwise to the maximum.
- Turn the voltage adjustment knob to obtain a voltage that is close to the desired value. Use the fine-tune knob if desired (where applicable). The C.V. indicator lights on the display.
Using the current-limiting adjustment in C.V. mode
- Switch on the device.
- Turn both the current adjustment knobs fully anticlockwise to the minimum, and the voltage adjustment knobs fully clockwise to the maximum.
- Short-circuit the output terminals by interconnecting them with the appropriate cable (60 V/16 A DC cable).
- Turn the current adjustment knob to the required current-limiting value. Use the fine-tune knob if desired (where applicable). The C.C. indicator lights on the display.
- Remove the short-circuit cable from both output terminals.
- Turn the voltage adjustment knob to the required value. Use the fine-tune knob if desired (where applicable). The C.V. indicator lights up on the display.
- Connect the load to the output terminals. If the current exceeds the current-limiting point, the C.C. indicator lights up on the display.
Connecting the Load
- Connect the load.
- You can read the output current and the output voltage from the display as soon as the device has been switched on.
- The C.V. indicator is lit if the device is in the C.V.-mode.
- The C.V. LED is off and the C.C. LED will light if the Amp display indicates a value that exceeds the installed value. When this happens, the device will automatically go into current-limiting mode. Install a load that will allow the device to function normally.
Cleaning and Maintenance
- Disconnect the device from the mains prior to maintenance activities.
- The power supply cables must not show any damage. Have a qualified technician maintain the device.
- Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
- There are no user-serviceable parts, apart from the fuse. Contact your dealer for spare parts if necessary.
- Store the device in a dry, well-ventilated, dust-free room.
