Product Instructions

1

Before powering on, check the stored and transported switch power supply. Inspect for any transport damage, such as loose screws, abnormal appearance, shaken off power cords or terminals, and dampness. Address any issues promptly.

2

The local power switch controls the internal auxiliary power. For safety, install an air switch at the power input terminal. Connect the ground wire and input power wire correctly according to the rear panel labels, ensuring input voltage matches the manual specifications.

3

The cooling fan is temperature-controlled and starts when internal temperatures exceed the control threshold. Fan speed varies dynamically with output voltage and current. Keep the fan inlet and outlet clear of obstructions.

4

If internal temperatures reach the overheating threshold, the machine will shut down automatically to prevent damage. It will resume operation once the temperature drops.

5

Avoid exposing the equipment to excessive dust, acid, corrosive gases, severe vibrations, bumps, rain, or direct sunlight.

6

Perform regular dust removal using dry compressed air to extend the lifespan of the equipment. Do not open the casing to prevent damage to high-voltage internal components.

7

When storing the device long-term, choose a dry and ventilated environment. If stored for over 6 months, power on and operate the supply for at least 30 minutes before usage.

8

Warning: Connect to load equipment only after the initial power-on test completes normally and error-free.

9

If any malfunction occurs, immediately turn off the switch and inspect both internal and external connections for loose screws or misplaced settings. Due to high internal voltages, do not disassemble or perform repairs without professional credentials to avoid electrical shock hazards.

Frequently Asked Questions

Does the power supply have overvoltage, overcurrent, overheating, or short circuit protection?

Yes, all of these safety protection mechanisms are fully integrated into the unit.

Is reverse polarity protection available?

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

Can the power supply be used at full power continuously for a long time?

No, for long-term operations, it is recommended to keep power usage below 80% of capacity to maintain safety headroom.

Is it easy to adjust the voltage and current?

Yes, adjustments can be easily made using the user-friendly dual knobs on the unit.

Are these high-power power supplies fully isolated?

Yes, our systems feature fully isolated designs for enhanced safety and operational stability.

What is the voltage regulation starting range?

The voltage regulation range starts directly from 1V.
