Product Instructions

1

Before powering on, check the stored and transported switch power supply. Check for damage during transportation, such as loose screws, abnormal appearance, shaken-off power cords/terminals, or dampness. Address any of these issues in a timely manner.

2

The local power switch controls the internal auxiliary power supply. For safety reasons, please add an air switch to the power input terminal. Connect the ground wire and input power wire correctly according to the rear panel label. Confirm the input power voltage is consistent with the manual indicator.

3

The cooling fan is temperature-controlled and starts when the internal temperature exceeds the threshold. The speed varies with the output voltage and current. Keep the fan inlets and outlets completely unobstructed during operation.

4

When internal temperatures reach the overheating threshold, the machine stops working automatically to prevent damage. It resumes operation automatically once the temperature drops.

5

Operate the equipment in environments where dust, acid, corrosive gases, or substances do not exceed normal limits. Avoid severe vibration, bumps, rain, and direct sunlight.

6

Regular dust removal (using dry compressed air) greatly improves service life and reliability. High pressure is present inside; do not open the casing or damage internal components.

7

When idle for extended periods, store the unit in a dry, ventilated room. If stored for over 6 months, power on the device and let it run for over half an hour before use.

8

Warning: Only connect to powered load equipment after confirming the power-on self-test is normal and error-free.

9

Malfunctions & Troubleshooting: If abnormal operation occurs, cut off the power switch immediately. Verify internal and external connections, tighten loose screws, and ensure all switches and knobs are positioned correctly. Do not unscrew the casing or attempt unauthorized self-repair due to high internal voltages. Please contact professional support promptly to resolve the issue.

Frequently Asked Questions

Q: Is there overvoltage, overcurrent, overheating, or short circuit protection?

A: Yes, the unit includes comprehensive protections for overvoltage, overcurrent, overheating, and short circuits.

Q: Is there reverse protection?

A: Reverse protection can be added as an optional customization with an additional cost.

Q: Can it be used at full power for a long time?

A: No. The power supply needs to be operated with excess capacity. Continuous operation is recommended at loads below 80%.

Q: Is it convenient to adjust the voltage and current?

A: Yes, it is very convenient. The voltage and current can be easily adjusted using the dual knobs.

Q: Is this high-power power supply isolated?

A: Yes, this power supply model is fully isolated.

Q: What is the voltage regulation range and is the power output sufficient?

A: The voltage regulation starts from 1V. The system is designed to provide sufficient and stable rated output power.
