Terminal Block Description:

• L, N: AC Power Input (Live and Neutral). Connect your main AC power source here.
• ດິນ: Earth Ground. Connect to a reliable earth ground for safety.
• -V (COM): DC Output Negative. Connect the negative terminal of your 24V DC load.
• +V: DC Output Positive. Connect the positive terminal of your 24V DC load.
• ADJ: ຜົນໄດ້ຮັບ Voltage Adjustment. Use a small screwdriver to fine-tune the output voltage within a small range (typically ±10%).

CAUTION: Double-check all wiring connections before applying power. Incorrect wiring can lead to damage, fire, or electric shock.

1. After completing all wiring and ensuring the input voltage selector is correct, connect the power supply to the AC mains.
2. The LED indicator (if present) on the unit should illuminate, indicating power is on.
3. ຢືນຢັນຜົນຜະລິດ voltage using a multimeter at the +V and -V terminals before connecting your load. Adjust the ADJ potentiometer if necessary.
4. Connect your 24V DC load to the +V and -V terminals.
5. The power supply features built-in protections against overcurrent, overvoltage, and short circuits. In case of a fault, the unit may shut down automatically. Disconnect power, resolve the issue, and then reconnect power.

ບໍາລຸງຮັກສາ

The PPOZYLPC S-400-24 is designed for reliable operation with minimal maintenance. Follow these guidelines:

• ທໍາຄວາມສະອາດ: Periodically clean the exterior of the unit, especially the ventilation grilles, to prevent dust buildup. Use a soft, dry cloth. Do not use liquid cleaners.
• ການລະບາຍອາກາດ: Ensure that the cooling fan and ventilation openings remain unobstructed at all times. Poor ventilation can lead to overheating and reduced lifespan.
• ການເຊື່ອມຕໍ່: Periodically check all wiring connections to ensure they remain tight and secure. Loose connections can cause intermittent operation or overheating.
