 Switching power supply 

GENERAL INFORMATIONS:

Switching power supply is widely used in automatic control, such as LED large screen, industrial control, communication equipment,instrument and meter, etc. The design of products confirm to IEC950, UL1950, UL1012, TUVEN60950, EMC LVD, etc. Main key components are improted and of stable quality.


FEATURES

●Compacted volume, light weight and convenient installation, High efficiency and low working temperature
●Main imported components of high dependabillity
●Soft start current design
●Inbuilt wave filter with extreme low waveform, Burn-out test at 100% full load
●Protection against short circuit, overload and overvoltage
