⚙ Product Instructions

1. Before powering on, verify the stored and transported switching power supply. Check for any transit damage (e.g., loose screws, abnormal appearance, disconnected cables or terminals, dampness). Address any issues immediately.

2. The local power switch operates the internal auxiliary power supply. For safety, install an air switch at the power input terminal to manage the main power input. Connect the ground wire and input power wires properly according to the designations on the rear panel. Ensure the input voltage aligns with the manual specifications.

3. The cooling fan is temperature-controlled. It initiates operation once the internal threshold temperature is reached. Speed dynamically adjusts based on load current and voltage. Keep the inlet and outlet vents unobstructed.

4. To prevent damage, the unit automatically shuts down if the internal temperature exceeds the overheat threshold. Once the system cools down, it will automatically restart and resume standard operation.

5. Keep the environment clean. Dust, acid, and corrosive gases must remain within normal limits. Avoid severe vibrations, mechanical shocks, exposure to rain, and direct sunlight.

6. Regular dust removal using dry compressed air improves product service life and operational reliability. Do not open the enclosure or damage internal elements, as high internal voltages are present.

7. Store the equipment in a dry, ventilated area when not in use. If stored for over 6 months, power on the device and let it run idle for at least 30 minutes.

8. Warning: Only connect load equipment after verifying that the power-on self-test completes successfully and error-free.

9. Malfunction Handling: If the unit performs abnormally, power down immediately. Check external and internal cabling for solid connections and look for loose hardware. Ensure all controls are set correctly. If the issue persists, do not open the casing. Due to dangerous high internal voltages, always seek professional maintenance promptly to resolve the issue.

Frequently Asked Questions (FAQ)

Q Does this unit support overvoltage, overcurrent, overheating, or short circuit protection?

Yes, it features integrated overvoltage, overcurrent, overheating, and short-circuit protections to secure the device and load.

Q Can reverse polarity protection be integrated?

Yes, reverse polarity protection can be custom-added as an upgrade configuration option.

Q Can it operate continuously at full output power?

No. For sustained, long-term operation, we recommend maintaining output loads below 80% to ensure optimal performance and safety margins.

Q How adjustable are the output voltage and current?

Voltage and current settings can be easily and precisely adjusted via standard dual knobs on the control panel.

Q Are high-power models designed with electrical isolation?

Yes, all of our high-power power supplies are engineered with fully isolated design architecture.

Q What is the voltage adjustment range, and is the power delivery accurate?

The voltage adjustment range starts from 1V. The equipment delivers stable, rated power specs accurately according to model selection.
