3.2 Негизги операция
- Күйгүзүү: Press the Power Switch to turn on the unit. The LED display will illuminate.
- Voltage: Use the V-COARSE knob for large voltage adjustments and the V-FINE knob for precise adjustments. Observe the voltagдисплейде окуу.
- Adjust Current Limit: Use the A-COARSE knob for large current limit adjustments and the A-FINE knob for precise adjustments. This sets the maximum current the power supply will deliver.
- Туташуу жүктөө: Connect your device or circuit to the output terminals. Ensure correct polarity (Positive to Positive, Negative to Negative).
- Монитордун чыгышы: The display will show the actual voltage, current, and power being delivered to the load. The C.V. or C.C. indicator will light up to show the operating mode.
- 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. Техникалык тейлөө
4.1 Жалпы кам көрүү
- 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 Муздатуу системасы
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 Сактагычты алмаштыруу
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 Ampere).
5. Кыйынчылыктарды
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.
- Ашык-томtage 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.
