1.Switch power supply matters needing attention:
1)The metal shell power line and the shell are generally connected to the ground (FG), to be reliable grounding, to ensure safety, not to mistakenly connect the shell to the zero line.
2)Before completion of the commissioning test, please check again and verify the connections on the terminals to ensure the input and output, AC and DC, single phase and multiphase, positive and negativeThe voltage and current value of right and keeps running.
For high power supply, there are generally three or more than three "+" input terminals and "-" output terminals, in fact, they belong to one output polarity, just for the convenience of user operation.
It adopts high quality components and has high reliability. Built in WMI filter has good anti-interference performance.
The DC ripple is small and the work efficiency is high. Design soft start circuit, AC surge current limit.
Low working temperature and long service life. The input voltage range is wide, which meets the global applicable standard.
The insulation property is good and the electric resistance is high. It has the functions of short circuit, overload, overvoltage and protection.
