3. Configuração
3.1 Desembalagem e Inspeção
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 Conectando à energia
- Certifique-se de que o interruptor de alimentação no painel frontal esteja na posição "DESLIGADO".
- 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 Inicialização Inicial
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. Instruções de operação
4.1 Painel frontal acimaview
The front panel features digital displays for voltage and current, control knobs for precise adjustment, and multiple output terminals.
4.2 Ajustando o Volumetage 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. Manutenção
5.1 Limpeza
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 Substituição de fusíveis
If the power supply does not turn on, check the fuse located on the rear panel near the AC inlet.
- Desconecte o cabo de alimentação da tomada CA.
- 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.
Aviso: Always replace fuses with the specified type and rating to prevent damage to the unit or risk of fire.
6. Solução De Problemas
| Problema | Possível causa | Solução |
|---|---|---|
| O dispositivo não liga. | No power from outlet, power cord disconnected, blown fuse. | Check power outlet, ensure power cord is securely connected, replace fuse (see Section 5.2). |
| Sem vol. De saídatage / atual. | Terminais de saída não conectados, volumetage/current knobs set to zero, OVP/OCP triggered. | Ensure load is properly connected, adjust voltage/current knobs, check for OVP/OCP indicators and reset if necessary. |
| Volume de saídatage/current is unstable. | Poor connection, faulty load, internal issue. | Check all connections, test with a different load. If problem persists, contact support. |
| Sobrevoltage Protection (OVP) indicator is on. | Volume de saídatage exceeded a safe limit. | Reduce the set voltage or check the load for issues. Power cycle the unit to reset OVP. |
