2. Instruccions de seguretat
Always adhere to the following safety precautions to prevent electric shock, fire, or damage to the device:
- Ensure the power supply is connected to a grounded outlet with the correct voltage (AC 230V).
- No utilitzeu el dispositiu en mullat o damp condicions.
- No obriu la c.asing; no hi ha peces a l'interior que l'usuari pugui reparar. Demaneu totes les tasques de manteniment a personal qualificat.
- Eviteu curtcircuitar els terminals de sortida.
- Ensure proper ventilation; do not block the ventilation openings.
- Desconnecteu el cable d'alimentació abans de netejar o moure la unitat.
- Use only the specified fuse type (F5A250VAC).

- Ventilador de refrigeració: Provides necessary airflow to dissipate heat.
- Entrada d'alimentació de CA: IEC C14 connector for the power cord.
- Portafusibles: Contains the main protective fuse (F5A250VAC).
4. Configuració
- Desembalatge: Carefully remove the power supply from its packaging. Inspect for any signs of damage during transit. Retain the packaging for future transport or storage.
- Col·locació: Place the unit on a stable, level surface. Ensure there is adequate space around the unit (at least 10 cm on all sides) for proper ventilation, especially around the rear cooling fan. Avoid placing it near heat sources or in direct sunlight.
- Connexió d'alimentació: Connect the supplied AC power cord to the AC power input on the rear panel of the power supply and then to a grounded AC 230V wall outlet.
- Comprovació inicial: Before connecting any load, turn on the power supply using the front panel power switch. The digital display should illuminate, showing voltage i lectures actuals.
5. Instruccions de funcionament
5.1 Encès i apagat
- To turn on, press the power switch on the front panel to the 'ON' (I) position.
- To turn off, press the power switch to the 'OFF' (O) position.
5.2 Ajust del volumtage i Actual
- Configuració Voltage: Rotate the 'VOLT Coarse' knob to set the approximate desired voltage. Use the 'VOLT Fine' knob for precise adjustments. Observe the voltage reading on the digital display.
- Setting Current Limit: Rotate the 'CURR Coarse' knob to set the approximate maximum current limit. Use the 'CURR Fine' knob for precise adjustments. This setting determines the maximum current the power supply will deliver before switching to Constant Current (C.C.) mode.
- Understanding CV/CC Modes:
- Vol. Constanttage (C.V.): When the load resistance is high enough that the current drawn is less than the set current limit, the power supply operates in C.V. mode, maintaining the set voltage. The C.V. indicator will be lit.
- Constant Current (C.C.): When the load resistance is low, causing the current drawn to reach the set current limit, the power supply switches to C.C. mode. The output voltage will drop to maintain the set current. The C.C. indicator will be lit.
5.3 Connecting a Load
- Ensure the power supply is turned off before connecting any load.
- Connect the positive (+) terminal of your load to the red output terminal of the power supply.
- Connect the negative (-) terminal of your load to the black output terminal of the power supply.
- If your load requires grounding, connect its ground terminal to the green/yellow output terminal of the power supply.
- After connecting the load, turn on the power supply. Adjust voltage and current as required for your application.
6. Manteniment
- Neteja: Disconnect the power supply from the mains before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
- Ventilació: Regularly check that the ventilation openings and cooling fan are free from dust and debris. Use compressed air to clear any blockages if necessary.
- Substitució de fusibles: If the unit fails to power on, the fuse may need replacement. Disconnect the power cord, locate the fuse holder on the rear panel, and replace the fuse with one of the identical type and rating (F5A250VAC).
- Emmagatzematge: Quan no la feu servir durant períodes prolongats, guardeu la font d'alimentació en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
7. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| La unitat no s'encén. | No power from outlet; Power cord loose; Blown fuse. | Check wall outlet; Ensure power cord is securely connected; Replace fuse (F5A250VAC). |
| Sense sortida voltage / actual. | Output terminals not connected; Voltage/current knobs set to zero; Unit in C.C. mode with low current limit. | Verify load connections; Adjust voltage and current knobs; Increase current limit or check load resistance. |
