4. Nhazi
4.1 Mwepu na nyocha
- Carefully remove the power supply from its packaging.
- Inspect the device for any signs of physical damage. If damage is found, do not operate the unit and contact your supplier.
- Ensure all accessories (e.g., power cord, test leads) are present.
4.2 Ntinye
- Place the power supply on a stable, level surface.
- Ensure adequate ventilation around the unit. Do not block the air vents on the sides and rear.
- Keep the device away from direct sunlight, heat sources, and excessive dust or moisture.
4.3 Njikọ ike
- Ensure the power switch on the front panel is in the "OFF" position.
- Connect the provided AC power cord to the power input socket on the rear panel.
- Plug the other end of the power cord into a suitable grounded AC power outlet (230V AC, 50Hz).
5. Ntuziaka ọrụ
5.1 Basic Operation (Output A and C)
- Ike Na: Flip the power switch to the "ON" position. The displays will illuminate.
- Pre-setting Voltage na ugbu a:
- Before connecting your load, turn the voltage adjustment knobs (coarse and fine) to set the desired output voltage.
- Adjust the current adjustment knobs (coarse and fine) to set the maximum current limit. This acts as a protection mechanism for your circuit.
- Ijikọ ibu: Connect the positive (+) terminal of your load to the red output terminal and the negative (-) terminal of your load to the black output terminal.
- Nleba anya: The displays will show the actual output voltage and current being supplied to your load.
- MfefetagNchedo (OVP): The OVP function protects the connected load from excessive voltage. Adjust the OVP knob to set the maximum permissible voltage. Ọ bụrụ na mmepụta voltage exceeds this limit, the power supply will shut down the output.
Figure 3: Connecting Test Leads
This image demonstrates how to connect test leads to the output terminals of the power supply. Red leads connect to positive terminals, and blue/black leads connect to negative terminals.
5.2 USB Output Operation (Output B-USB)
The central Output B-USB section provides dedicated USB power outputs.
- Connect your USB device to one of the USB ports (USB-B1 or USB-B2).
- Use the "MODE" and "SHOW VALUE" controls to select the desired USB output voltage (e.g., 5V, 9V, 12V) and monitor its status.

A hand is shown adjusting one of the control knobs on the front panel, illustrating the user interaction with the device's settings.
5.3 Output Modes (Parallel, Series, Independent)
The VLP-2403 offers flexible output configurations for Outputs A and C:
- Independent Mode (IND): Outputs A and C operate as two separate, isolated power supplies.
- Series Mode (SER): Outputs A and C are connected in series to provide a higher voltage (up to 80V). Ensure proper wiring and voltage ntọala.
- Parallel Mode (PAR): Outputs A and C are connected in parallel to provide a higher current (up to 6A). Ensure proper wiring and current settings.
Refer to the front panel "MODE" switch in the Output B-USB section to select the desired configuration for Outputs A and C.
6. Nlekọta
6.1 Nhicha
- Disconnect the power supply from the mains before cleaning.
- Jiri nwayọ hichaa mpụta, damp akwa . Ejila ihe nchacha abrasive ma ọ bụ ihe mgbaze.
- Ensure no liquid enters the device.
6.2 Mgba ikuku
- Regularly check that the ventilation openings on the sides and rear are free from dust and obstructions.
- Blocked vents can lead to overheating and damage.
6.3 Mgbanwe Fuse
If the power supply does not turn on, check the fuse located in the AC input socket on the rear panel. Replace it only with a fuse of the same type and rating (e.g., T 3.15A / 250V).
