- USB Quick Charge: For fast charging, connect your USB-compatible device to the Quick Charge port. The power supply's built-in chip will identify the fast charging protocol.
4. Viðhald
4.1 Almenn umönnun
- Keep the power supply clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
- Avoid operating the unit in environments with excessive dust, humidity, or extreme temperatures.
- Do not block the ventilation openings. Ensure adequate airflow around the unit.
4.2 Kælikerfi
The DPS3010U is equipped with an internal cooling fan to dissipate heat during operation. Ensure the fan intake and exhaust vents are clear of obstructions to maintain optimal performance and prevent overheating.

4.3 Skipt um öryggi
If the unit fails to power on, check the fuse located in the fuse box on the rear panel. Replace it with a fuse of the same type and rating (3 Amphér).
5. Bilanagreining
5.1 Protection Modes
The power supply incorporates several protection features to safeguard both the unit and the connected load:
- Current Limiting Protection: When the load current exceeds the set current limit, the power supply will enter Constant Current (C.C.) mode, limiting the output current to the set value.
- Short Circuit Alarm Stop Output and Self-Recovery: In case of a short circuit at the output terminals, the unit will stop outputting power and trigger an alarm. Once the short circuit is removed, the unit will automatically recover and resume normal operation.
- Yfir-Voltage Protection (OVP) / Over-Current Protection (OCP) / Over-Temperature Protection: These internal protections will shut down the output if voltage, current, or internal temperature exceed safe limits.
