Configuració
1. Inspecció Inicial
Unpack the power supply and inspect it for any signs of physical damage. If any damage is found, do not proceed with installation and contact customer support.
2. Volum d’entradatage Selection (CRITICAL STEP)
The power supply has a switch to select between 110V AC and 220V AC input voltage. Before connecting the power supply to any AC source, ensure this switch is set to match your local mains voltage. The default setting may be 220V. Refer to Figure 3 for the location of this switch.
- For 110V-120V AC regions (e.g., North America), set the switch to 110 V.
- For 220V-240V AC regions (e.g., Europe, Middle East), set the switch to 220 V.
ADVERTIMENT: Operating the unit with an incorrect voltage selection can cause irreversible damage to the power supply and connected devices.
3. Connexions de cablejat
Refer to Figure 2 for the terminal block layout. Ensure all connections are made securely and correctly.
- Entrada de CA:
- Connect the Live (L) wire from your AC source to the 'L' terminal.
- Connect the Neutral (N) wire from your AC source to the 'N' terminal.
- Connect the Earth Ground wire to the '⊗' (ground) terminal.
- Sortida de corrent continu:
- Connecteu el cable positiu (+) de la vostra càrrega al terminal '+V'.
- Connecteu el cable negatiu (-) de la vostra càrrega al terminal '-V'.
Use appropriate wire gauges for your application. For the maximum 20A output, ensure wires are capable of handling this current safely.
Instruccions de funcionament
1. Encès
After all connections are made and the input voltage switch is correctly set, apply AC power to the unit. The dual LED display will illuminate, showing the current output voltage i corrent.
2. Ajustar el volum de sortidatage
Rotate the potentiometer knob (refer to Figure 1) to adjust the DC output voltage. Turn clockwise to increase voltage and counter-clockwise to decrease it. The LED display will show the adjusted voltage in real-time. The voltage precision is 0.1V.
3. Monitoring Output
The dual LED display provides continuous monitoring of the output voltage (in Volts) and the current drawn by the load (in Amperes). Note that the maximum current is 20A, but the actual current displayed will depend on the connected load and cannot be regulated directly by the power supply.
Manteniment
- Neteja: Keep the power supply clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
- Ventilació: Regularly check that the cooling fan and ventilation openings are not obstructed. Ensure proper airflow to prevent overheating.
- Funcionament del ventilador: The cooling fan operates automatically when the internal temperature reaches a certain threshold, especially during high power output. A slight noise from the fan is normal during operation.
- Emmagatzematge: When not in use for extended periods, store the power supply in a cool, dry place away from direct sunlight and moisture.
Resolució de problemes
If you encounter issues with your DROK power supply, refer to the table below for common problems and solutions.
| Problema | Causa possible | Solució |
|---|---|---|
| No power, display off | No AC input; Incorrect input voltage switch setting; Internal fuse blown. | Check AC power connection. Verify 110V/220V switch setting. If fuse is suspected, contact support. |
| No DC output voltage | Output short circuit; Overload protection activated; Voltage set to 0V. | Check load for short circuits. Reduce load if overloaded. Adjust voltage potentiometer. |
| Vol de sortida incorrectatage es mostra | Potentiometer not adjusted correctly. | Gira el voltage adjustment potentiometer until the desired voltages mostra e. |
| Cooling fan not running | Low power output (fan activates automatically at higher temperatures/loads); Fan obstructed. | This is normal for low loads. If unit is hot and fan is not running, check for obstructions. |
| Output current is lower than expected | Load resistance is too high; Overload protection. | The current is determined by the load. Ensure your load is drawing the expected current. Check for overload conditions. |
