How to Use:

1. Connect the supplied input cable to a compatible AC mains supply matching the selected input voltage variant.
2. Connect the output cable to the device under test, observing correct polarity.
3. Power on the unit and set the desired voltage and current for each channel.
4. Use the independent output ON/OFF control to enable only the required channels.
5. Store frequently used settings using the 3 groups of memory per channel.
6. For automated testing, connect via USB, RS232, or RS485 and control through compatible PC software.

Installation and Wiring:

Ensure the power supply is placed on a stable, ventilated surface and the intelligent cooling fan is not blocked. Use the supplied input cable for AC mains connection and the output cable for connecting to the load. Set OVP and OCP limits according to the connected device to help protect against abnormal voltage or current. Verify voltage and current settings before enabling each output channel.

Compatibility:
