- VoltagButoane de reglare: Fine and coarse adjustment for output voltage.
- Butoane de reglare a curentului: Fine and coarse adjustment for output current limit.
- Terminale de ieșire: Red (+) and Black (-) terminals for connecting loads.
- Output B-USB Section: Controls and USB ports for dedicated USB power output.
- OVP (Overvoltage Protection) Adjustment: Sets the overvoltaglimita de protectie.
4. Configurare
4.1 Despachetarea și inspecția
- 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 Plasarea
- 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 Conexiune la alimentare
- 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. Instrucțiuni de utilizare
5.1 Basic Operation (Output A and C)
- Pornire: Flip the power switch to the "ON" position. The displays will illuminate.
- Volum presetattage și curent:
- 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.
- Conectarea încărcăturii: Connect the positive (+) terminal of your load to the red output terminal and the negative (-) terminal of your load to the black output terminal.
- Monitorizare: The displays will show the actual output voltage and current being supplied to your load.
- OvervoltagProtecție e (OVP): The OVP function protects the connected load from excessive voltage. Adjust the OVP knob to set the maximum permissible voltage. Dacă volumul de ieșiretage 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 setări.
- 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. Întreținere
6.1 Curățare
- Disconnect the power supply from the mains before cleaning.
- Ștergeți exteriorul cu un material moale, damp pânză. Nu utilizați agenți de curățare abrazivi sau solvenți.
