2. Safety Information

For your safety and to prevent damage to the unit, observe the following precautions:

• Indoor Use Only: This power supply is designed for indoor use in dry environments. Do not expose to water, moisture, or high humidity.
• Proper Ventilation: Ensure adequate airflow around the unit. Do not block ventilation holes. The built-in cooling fan requires clear space to operate effectively.
• Input Voltage Selection: Before connecting power, verify the 110V/220V switch is set correctly for your region's AC supply. Incorrect setting can cause severe damage.
• Professional Installation Recommended: Wiring should be performed by a qualified electrician to ensure proper and safe connections.
• Overload Protection: Do not exceed the maximum output current of 70A. Overloading can trigger built-in protections or damage the unit.
• Grounding: Ensure the unit is properly grounded to prevent electrical shock.
• No User Serviceable Parts: Do not open the casing. Refer all servicing to qualified personnel.

3. Product Features

• Input Voltage: AC 110V/220V (selectable via switch).
• Output Voltage: DC 5V.
• Output Current: 1A to 70A (350W max).
• Adjustable Output: Output voltage is ±10% adjustable via a potentiometer.
• Multiple Output Channels: Features three sets of output channels for versatile connectivity.
• Cooling System: Built-in cooling fan with temperature detector. Fan activates when internal temperature reaches 113°F (45°C) for efficient heat dissipation.

4. Setup

Follow these steps for proper setup:

1. Verify Input Voltage Switch: Locate the 110V/220V selector switch on the side of the unit. Ensure it is set to match your local AC power supply (e.g., 110V for USA, 220V for Europe). Failure to do so will damage the unit.
2. Mounting: Securely mount the power supply in a well-ventilated area, away from heat sources and flammable materials.
3. AC Input Wiring: Connect your AC power cord (not included) to the input terminals.
   • L: Live wire
   • N: Neutral wire
   • ⌂: Ground wire (Earth)
   Ensure all connections are tight and secure.
4. DC Output Wiring: Connect your DC load to the output terminals.
   • +V: Positive DC output
   • -V: Negative DC output (GND)
   The unit provides three sets of output terminals for convenience.
5. Initial Power On: After all connections are made and verified, connect the AC power cord to the wall outlet. The indicator light on the unit should illuminate.

5. Operating

Once the power supply is set up, it is ready for operation.

• Voltage Adjustment: The output voltage can be fine-tuned by ±10% using the small potentiometer (labeled 'ADJ' or 'VR1') located near the output terminals. Use a small screwdriver to carefully turn the potentiometer clockwise to increase voltage or counter-clockwise to decrease it. Always verify the output voltage with a multimeter before connecting sensitive devices.
• Cooling Fan Operation: The integrated cooling fan will automatically activate when the internal temperature reaches approximately 113°F (45°C). This ensures optimal operating temperature and extends the lifespan of the unit. The fan may not run constantly, especially under light loads or in cooler environments.
• Load Management: Ensure the total current draw of your connected devices does not exceed 70A. While the unit has overload protection, continuous operation near or above its maximum capacity can reduce its lifespan.

6. Maintenance

Minimal maintenance is required for this power supply.

• Cleaning: Periodically clean the exterior of the unit with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation openings are free from dust and debris.
• Ventilation: Regularly check that the cooling fan and ventilation grilles are not obstructed. Proper airflow is crucial for heat dissipation.
• Connections: Occasionally inspect all wiring connections to ensure they remain tight and secure. Loose connections can lead to overheating or intermittent operation.
• Storage: If storing the unit for an extended period, keep it in a cool, dry place, away from direct sunlight and extreme temperatures.
