4. Configuració
- Desembalatge: Carefully remove the power supply and all accessories from the packaging. Verify that all components listed in the package contents are present: 1 x Adjustable DC Power Supply, 1 x Power line, 1 x Communication Serial Line, 1 x Tester line.
- Col·locació: Place the unit on a stable, level surface with adequate ventilation. Ensure that the air vents are not obstructed.
- Connexió d'alimentació: Connect the provided power line to the AC input on the rear of the power supply and then to a grounded 220V AC power outlet.
- Comprovació inicial: Before connecting any load, ensure the power switch on the front panel is in the OFF position.
5. Instruccions de funcionament
5.1 Engegada/apagada
- To power on, flip the power switch on the front panel to the ON position. The LCD display will illuminate.
- Per apagar-lo, gireu l'interruptor d'alimentació a la posició OFF.
5.2 Configuració Voltage i Actual
- Ensure no load is connected or the load is safely disconnected before adjusting settings.
- Use the rotary encoder (shuttle design) to adjust the desired voltage and current values. The LCD display will show the set values.
- The power supply allows continuous adjustment of both voltage (0-400V) and current (0-1A) within its rated range.
- Connect your load to the output terminals (red for positive, black for negative).
- La pantalla mostrarà el volum de sortida realtage i corrent.
5.3 Programmable Control (PC/PLC)
This power supply supports external control via a PC or PLC. Use the provided Communication Serial Line to connect the unit to a computer. With the dedicated software, you can remotely set output voltage and current values and monitor the power supply's working status in real-time. This feature is useful for automated testing and precise load characteristic analysis.
6. Manteniment
- Neteja: Desconnecteu l'alimentació de la presa de corrent abans de netejar-lo. Feu servir un drap suau i sec per netejar l'exterior. No utilitzeu netejadors líquids ni dissolvents.
- Ventilació: Regularly check that the ventilation openings are clear of dust and debris to ensure proper airflow and prevent overheating.
- 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.
