Operating Instructions

1Pre-power Inspection

Check the stored and transported switch power supply before powering on. Ensure no damage occurred during transit: check for loose screws, abnormal appearance, disconnected terminals/power cords, or moisture. Address any issues promptly.

2Power Input Safety

The local power switch controls the internal auxiliary power supply. For safety, install an air switch at the power input terminal to control main power. Connect the ground wire and input power wire correctly as labeled on the rear panel. Verify input voltage matches the manual specification.

3Cooling Fan & Ventilation

The cooling fan is temperature-controlled and starts when internal temperatures reach the preset threshold. Fan speed varies dynamically with output voltage and current load. Do not block the fan's air inlet or outlet.

4Overheat Shutoff

If internal temperatures exceed safety levels, the system automatically shuts down to prevent damage. It resumes operations automatically once the unit cools down.

5Operating Environment

Avoid using the equipment in environments exceeding standard levels of dust, acid, or corrosive gases. Avoid exposure to rain, severe vibration, physical impacts, and direct sunlight.

6Maintenance & Dust Removal

Regular dust removal extends service life and reliability. Dry compressed air can be used for cleaning. Do not open the outer casing or damage internal components during cleaning due to internal high voltage risk.

7Long-term Storage

If left idle long-term, store the power supply in a dry, ventilated room. If stored for over 6 months, power on the device and run it for at least 30 minutes.

8Load Connection Warning

Only connect your load equipment to the power supply after verifying that power-on self-tests run normally without errors.

9Troubleshooting

If abnormal behavior occurs after startup, switch off the power supply immediately. Check all external connections, screws, and dial configurations. If the issue persists, do not open the casing. High voltage is present inside. Please contact authorized technical support promptly.

Frequently Asked Questions (FAQ)

Does this power supply feature overvoltage, overcurrent, overheating, or short circuit protection?

Yes. The system is equipped with comprehensive protection protocols, including overcurrent, overvoltage, overheating, and short-circuit protections.

Is reverse polarity protection available for this unit?

Yes, reverse polarity protection can be customized and integrated into the unit upon request.

Can the system be run at full power continuously?

For long-term continuous operations, it is recommended to keep the operating load below 80% of maximum capacity to ensure stability and system longevity.

How convenient is it to adjust the voltage and current settings?

It is very convenient. The power supply design features dedicated dual control knobs for user-friendly and precise adjustments of voltage and current.

Are these high-power power supplies fully isolated?

Yes, our high-power DC switching power supplies are completely isolated to ensure safe operation.

What is the starting voltage regulation range?

The voltage regulation starts from 1V, offering a wide control spectrum.
