3. Nhazi
3.1 Mwepu na nyocha
Carefully remove the power supply from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. If any damage is found, do not operate the device and contact your supplier.
3.2 Ijikọ n'ike
- Ensure the power switch on the front panel is in the "OFF" position.
- Connect the provided power cord to the AC inlet on the rear panel of the power supply.
- Plug the other end of the power cord into a standard 230V AC, 50Hz grounded electrical outlet.

3.3 Ike mbido
After connecting the power cord, switch the power supply ON using the main power switch on the front panel. The display should illuminate, indicating the device is ready for operation.
4. Ntuziaka ọrụ
4.1 Ogwe ihu n'ihuview

The front panel features digital displays for voltage and current, control knobs for precise adjustment, and multiple output terminals.
4.2 Mpịakọta Mgbanwetage and Current (Output A)
- Connect your load to the main output terminals (Output A). Use the red terminal for positive (+) and the black terminal for negative (-). The yellow terminal is for ground.
- Turn the "VOLT" knob to set the desired output voltage. The digital display will show the set voltage.
- Turn the "AMPERE" knob to set the desired current limit. This acts as a current limiter to protect your circuit.
- The "C-LIMIT" indicator will illuminate if the current limit is reached.
- The "OVP" (Overvoltage Protection) indicator will illuminate if an overvoltage condition occurs.

4.3 Using the USB Outputs (Output B-USB)
The VLP-1602 includes dedicated USB outputs for testing and development purposes. These outputs can be used to stress connected USB devices.
- Connect your USB device to one of the USB-B1 or USB-B2 ports.
- Use the "MODE" switch to select the desired USB output mode (e.g., 4.8-5.2V, 4.5-4.7V, Normal).
- The "ADJ" knob allows for fine adjustment of the USB output voltage within the selected mode.
- Refer to the labels near the USB ports for specific voltage and current ratings (e.g., USB-B1: 5V/2A, USB-B2: 12V/0.5A).
5. Nlekọta
5.1 Nhicha
To clean the exterior of the power supply, use a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and unplugged before cleaning.
5.2 Mgbanwe Fuse
If the power supply does not turn on, check the fuse located on the rear panel near the AC inlet.
- Kwupu eriri ike na oghere AC.
- Use a flat-head screwdriver to open the fuse holder.
- Replace the blown fuse with a new fuse of the same type and rating (T 1.6A / 250V).
- Close the fuse holder securely.
Ịdọ aka ná ntị: Always replace fuses with the specified type and rating to prevent damage to the unit or risk of fire.
