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. Specification -Input voltage range: Single phase 220V±
30%(154~286V) Three phase 380V± 30%(266~494V) -Output voltage:
Single phase 220V Three phase 380V -Frequency: 50 or 60 Hz± 1 Hz
-Galvanic isolation -High common and normal mode noise attenuation
-Surge and brownout protection -Sine wave output(regardless of
input waveform) -Low installation and running costs(maintenance
free) -High Mean Time Between Failure(MTBF) -Easy to install 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 5. Industrial
enterprises 6. Medical institutes We reserve the right to change
