Product Description

Overview
Constant Voltage Transformer (CVT) is ideal maintenance free solution for loads that can Suffer erratic oeration or be damaged by electrcal noise(Common or series mode), loca transient, mains power sags, Surges and brownouts because of its resonant property. When faced with with an extreme transient such a local lighting strike, The CVT will present a low impedance to the main protecting both itself and any connected loads. The ferroresonant 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.

Features
1 Fast Response time less than 25ns effectively guard electro-equipment.
2 Easy installation parallel wiring with power line.
3 Poor quality tendency indicator LED indicates the state of work.
4 Repeat use many times It can repeat use after attack several times without destruction, lower investment cost.
5 Communication function: A remote communication junction for monitor and warn when poor quality appears. Adopted use in no-man station at mountain far apart area.
6 Long life: Normal operating period 10~20 years.
7 Record the times of lightning or surge is available as required.

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)


Applications
1. Sensitive electronic equipment
2. Telecom centers
3. Automatic control centers
4. Intelligent mansions
