CVT Type Automatic Voltage Regulator
Product Introduction

 

Specially for high precision instrument

CVT Type Automatic Voltage Regulator is in small size, maintenance –free and service – free. It is highly adaptable to demand environment. Solid and durable resonance AVR has the following 10 advantages and will be the top choice for you in selecting AVR.

 

Feature:
         

Determined CVT Type AVR

 

Total insulation between input and output

 

Output wave is sine wave and is not affected
by input waveform
 

 

Best noise filtering function (higher than 60 db).
Best resistance to thunder strike, noise, electrostatic
and high voltage pulse
         

Fortified CVT Type AVR

 

Wide Range Input Voltage

 

No electronic controlled circuit, only made up
with 2 independent element. Excellent voltage
regulation function and probability of mis-action is zero
 

 

Under drastic rise or drop of input voltage (±45%)
output voltage will be steady at ±2.5%
         

Most durable CVT Type AVR

 

Perfect Protection

 

Simple structure, excellent durability, extremely
long MTBF-30 years overseas, in Taiwan, has
been in service since 1973 (20 years warranty for the main body)
 

 

Uninterrupted Power Supply (UPS) characterized,
power off 1-2 cycle (3/4 load) has not effect on output
         

Delicate designed CVT Type AVR

 

AVR main body generates no noise

 

Output end short circuit or overload, current will
be limited automatically and is ready for use when
when short circuit or overload is excluded (short
circuit for 24 hours will not cause any damage)
 

 

The main body is ultra-insulated transformer
that prevents peak wave, sink wave and high/low
frequency and has best interference fending
ability (more than 60db)
         

Excellent Response Time

 

Viable Application

 

Response Time is extremely rapid and is within 1.5 cycle  

 

Input voltage 110V or 220V
Output voltage can have 110V/ 220V at the same time
         
Application:

 

Electronic Test
Instrument
R&D Instrument Optoelectronic
Industry
Multimedia
Equipment
Industrial Computer Audio Equipment
