Sell Constant Voltage Transformer

Constant Voltage Transformer You May Also Be Interested In: constant voltage transformer isolation transformer poly propylene type test voltage transformer
This series Constant Voltage Transformer(CVT) combines isolation transformer, bi-directional filter, and wide range voltage regulation, 3 functions integrated in 1. Isolating between input and output, high interference suppression for 3rd-13th harmonic, surge, rush and lightning pulses in main network. It is specially used for apparatus and instruments that are sensitive to heavy interference in mains. Its specification quality has been approved by space science and technical group for type test and environmental test. It has mentioned as special used in military.

Main specifications and features:
Input voltage range: Single phase 220V130%(154~286V)
Three phase 380V130%(266~494V)
Output voltage: Single phase 220V
Three phase 380V
Frequency: 50 or 60 Hz 11 Hz
Output voltage total harmonic distortion:<=3.5%( Even input square wave,
miscellaneous wave, the output is sine wave. )
Response time: 20~40ms
Anti-interference: >=50dB (suppression for 3rd to 13th harmonic more than (9 years)
It can withstand <=10ms when power failures to protect the data safety.
It is high reliable without movable part contact point, electronic controller, only one transformer and some poly propylene A. C. condenser.
Isolation between input and output.
This series have 4 types product:
1. Sine wave stability type (more stability, output sine wave)
2. Sine wave anti-interference type (more anti-interference, output sine wave)
3. Sine wave enhanced type (more input voltage range, output sine wave)
4. Trapezoid wave type rectify type (more efficient in rectifying circuit)
