Introduction
This manual provides detailed instructions for the safe and efficient operation of your DROK 48V 10A 480W Adjustable AC to DC Power Supply. This device converts AC input voltage (110V or 220V) to a variable DC output voltage ranging from 0-48V, with a maximum current of 10A and a rated power of 480W. It is equipped with an LED screen for voltage display, a heat sink, and a cooling fan for temperature management.

Setup Instructions
1. Input Voltage Selection
Before connecting the power supply to an AC source, ensure the input voltage switch is set correctly for your region (110V or 220V). The default setting is typically 220V. Incorrect selection can damage the unit.

2. Wiring Connections
Connect the AC input wires to the terminals labeled L (Live), N (Neutral), and ⌂ (Ground). For DC output, connect your load to the V+ (DC output positive) and V- (DC output negative) terminals. Ensure all connections are secure to prevent electrical hazards.
- L: Live wire
- N: Null wire
- ⌂: Ground
- V+: DC output positive
- V-: DC output negative

Operating Instructions
1. Power On and Voltage Adjustment
After securing all connections and verifying the input voltage switch, connect the power supply to the AC source. The LED display will illuminate. Use the adjustable potentiometer knob to set the desired DC output voltage between 0V and 48V. The voltage precision is 0.1V.

2. Current Output
This power supply provides a fixed maximum current of 10A. The actual current drawn will be determined by the connected load, up to this 10A limit. The current output is not adjustable. Ensure your connected devices require less than 10A to prevent damage.
3. LED Display
The integrated LED screen clearly displays the output voltage. Some models may feature dual displays for both voltage and current. This model (200570) features a single display for voltage.

Maintenance
1. Cooling System
The power supply includes a built-in cooling fan that automatically activates when the internal temperature rises during high power operation. Ensure the fan vents are not obstructed to allow for proper airflow and prevent overheating.

2. Cleaning
Periodically clean the exterior of the power supply with a dry, soft cloth. Do not use liquid cleaners or allow moisture to enter the unit. Ensure the device is unplugged before cleaning.
Troubleshooting
- No Output Voltage: Check the AC input connections and ensure the input voltage switch (110V/220V) is correctly set for your local power grid.
- Incorrect Output Voltage: Verify the potentiometer knob is adjusted to the desired voltage. If the display shows an unexpected value, ensure the multimeter used for verification is calibrated and correctly connected.
- Overload Protection: The unit features Over Load Protection, Over Voltage Protection, and Short Circuit Protection. If the power supply shuts down, disconnect the load, check for short circuits, and reduce the load if it exceeds 10A.
- Fan Not Running: The cooling fan activates automatically when the internal temperature reaches a certain threshold. If the unit is not under heavy load, the fan may not be active. If the unit is hot and the fan is not running, ensure vents are clear.
