The switch mode power supply developed our company adopting international high and new technology, which applies to automation fields such as: LED large screen, engineering control equipment, communication equip -ment, instruments & meters, etc. This series of products is designed according to IEC 950 , UC1950 , UL1012, TUVEN60950,EMC LVD
and so on. Employing imported elements, its quality is stable and reliable, and theproducts are popular throughout the country and far sold to America a nd Europe. Welcome to negotiate and cooperate with us.
Features
Imported elements, high reliability, built-in filter, low ripple, each article has passed full load and burn - in test, compac-
tness, light weight, inner mounted with inrush current suppressing circuit and output capacitor whose working temperature
is lower than 105℃, it shows high efficiency and long service life, so it is suitable for all-range voltage, short circuit
protection, overload protection, over-voltage protection.
