Features 

 CWY series power supply with full isolation, shielding, filtering of the structural features, it has the following other types of communication regulated product does not have the excellent performance. 
 1, the maximum input voltage range, semi-load voltage range of up to 50%; 30% of the load voltage range of up to 60%. The advantage is that any other exchange of power products can not match. 
 2, the use of the device at least, the line of simple structure, which is the highest reliability of power supply. 
 3, the most comprehensive anti-interference ability, interference of frequency, amplitude, the effect is much better with any type of clean AC power supply, even against amplitude of 3000V peak lightning shock induction interference. 
 4, the voltage regulation fastest in the 20ms to be completed within a course of voltage stability is the other type of power supply can not be compared. 5, strong protection function, the regulator's output can be short in any manner without causing a direct short circuit damage to the regulator (when the output voltage is automatically reduced to 0V, to eliminate short-circuit output voltage will be automatically restored after the normal output). 
 Because of these performance characteristics, CWY series AC power supply are widely used purification and computer systems, program-controlled switches, microwave, wireless base stations, analytical instruments, radio and television system as the high reliability of the isolation, interference, clean power supply used. Also apply for general cleaning of high-quality electronic equipment power supply voltage. 
 Working principle of price and other reasons, all CWY series of regulators are not suitably with air conditioning, elevators, heaters and other large Inrush current power regulator settings, they should not be used for the frequency of over 50Hz ±. For the three-phase unbalanced load greater than 20% of the occasions should be used with caution.
