Have you ever seen such a big 400W power supply?

Switch power supply matters needing attention: 

1, the shell power line and the shell is generally connected with the ground (FG), to be

By grounding, to ensure safety, the casing can not be mistakenly connected to the zero line.

2. Please check and proofread again before the test run is finished

The wiring on the terminals ensures the input and output, AC and DC

Flow, single phase and multiphase, positive and negative electrodesVoltage value and current value are positive

It certainly keeps running.
3, for high-power power supply, generally have three or more than three

"+" input terminals and "-" output terminals, in fact, belong to the same category

An output polarity, just for the user to operate easily
4. It has over-current short-circuit protection function, self cooling heat sink and integrated circuit

95% full load, guaranteed for two years. One year for new!

Two. Product characteristics:

1, using imported components, high reliability. Built in WMI filter, anti

Good jamming performance.

2, DC ripple small, high efficiency. Soft start circuit is designed

flowInrush current limit.

3, low working temperature, long service life. The input voltage range is wide and conforms to the input voltage range

Global applicable standards.

4, good insulation performance, high electrical resistance. With short circuit and overload,

Overvoltage and protection function.

 Three. Instructions for installation

 1, outdoor use only vertical installation, to prevent side water caused


 2, to ensure good heat dissipation environment, prohibit covering the shell.

3, the accurate calculation of the load power, do not overload, flash light

Shuo, please reduce the number of slides.

4, before the use of power, to confirm whether the power line is properly connected, is strictly prohibited

Reverse connection.
