Determined CVT Type AVR
Output wave is sine wave and is not affected by input waveform
Fortified CVT Type AVR
No electronic controlled circuit, only made up with 2 independent element. Excellent voltage
regulation function and probability of mis-action is zero
Most durable CVT Type AVR
Simple structure, excellent durability, extremely long MTBF-40 years overseas, inTaiwan, has
been in service since 1973 (20 years warranty for the main body)
Delicate designed CVT Type AVR
Output end short circuit or overload, current will be limited automatically and is ready for use when
short circuit or overload is excluded (short circuit for 24 hours will not cause any damage)
Total insulation between input and output
Best noise filtering function (higher than 60 db). Best resistance to thunder strike, noise, electrostatic
and high voltage pulse
Perfect Protection
Uninterrupted Power Supply (UPS) characterized, power off 1-2 cycle (3/4 load) has not effect on output
Wide Range Input Voltage
Under drastic rise or drop of input voltage (±45%)
output voltage will be steady at ±2.5%
Excellent Response Time
Response Time is extremely rapid and is within 1.5 cycle
Viable Application
Input voltage 110V or 220V
Output voltage can have 110V/ 220V at the same time (2KVA and above)
AVR main body generates no noise
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)
