Wenzhou Modern Group is the best China constant voltage transformer, cvt manufacturer and supplier, as a professional company, we have our own factory. Welcome to wholesale constant voltage transformer, cvt, cvt, contant voltage transformer, constant volatage regulator, ferroresonant transformer, ferroresonant regulator products from us.

Constant Voltage Transformers(CVT) are ideal maintenance free solutions for loads that can suffer erratic operation or be damaged by electrical noise(common or series mode), local transient, mains power sags, surges and brownouts because of its resonant property.When faced with an extreme transient such as a local lighting strike, the CVT will present a low impedance to the mains protecting both itself and any connected loads. The ferro-resonant transformer technology ensures that CVT will generate a perfect sine wave output even when fed from square or quasi-square wave sources. A CVT is also the most efficient way to drive a switched mode power supply(SMPS), and provides harmonic buffering.
