Product Instructions & Safety Guidelines

1 Before powering on, inspect the stored and transported switching power supply. Check for any transit damage such as loose screws, abnormal appearance, dislodged cables, or signs of dampness. Address any issues immediately.
2 The local power switch controls internal auxiliary power. For safety, install an external air switch on the input line. Connect the ground wire and input power wire correctly following the rear panel labeling. Ensure input voltage matches manual specifications.
3 The temperature-controlled cooling fan activates when internal threshold temperatures are reached. Fan speed will dynamically adjust depending on the load output voltage and current. Keep the fan air intake and exhaust vents clear.
4 An automatic overheat shutdown is integrated. If internal temperatures reach high thresholds, the machine will shut off to prevent damage and resume operation once it cools.
5 Ensure the operating environment remains free from excessive dust, acid, corrosive elements, severe vibration, water exposure, and direct sunlight.
6 Conduct regular dust cleaning to extend system lifespan. Use dry compressed air and do not open the casing to prevent contact with internal high-voltage areas.
7 Store inactive equipment in dry, well-ventilated locations. If stored for over 6 months, power on and operate the supply for at least half an hour before use.
8 Warning: Always perform a startup test and confirm normal behavior before connecting to any live load equipment.
9 Troubleshooting: If abnormality is found, power off immediately and check wiring connections. Do not open the casing unauthorized due to internal high voltage danger.

Frequently Asked Questions

Are there safety protection features built-in?

Yes, the power supply includes comprehensive overvoltage, overcurrent, overheating, and short-circuit protection.

Is reverse polarity protection available?

Yes, reverse polarity protection can be custom added upon request.

Can this unit run at full power continuously?

No, we recommend maintaining a safety headroom. The unit can be operated continuously for extended durations at loads below 80% capacity.

How are the output voltage and current adjusted?

Adjustments are simple and precise using the integrated dual knobs on the panel.

Are these high-power power supplies isolated?

Yes, all our high-power power supplies feature a fully isolated design.

What is the range of voltage regulation?

The output voltage regulation starts from 1V.
