共振式電圧安定装置(ELA)

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.
モデル : ELA series

Insulated Output from Input

High Insulation Main Body CVT

Switching Freely between
110V and 220V






Best noise filtering ability allowing excellent resistance to thunder strike, noise, electrostatic and high voltage pulse



Use laminated insulated material and repeated impregnated main body and has durability of more than 20 years



Input and output voltage can be changed per needs


Elegant Appearance Solid and Durable

Top Level AC Capacitor







Made up only with CVT and capacitor, without electronic element and is with ultra high MTBF

Use top brand AC capacitor and can be interchanged magnetic energy of CVT and electric energy

text3.gifDetermined CVT Type AVR

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

text3.gifFortified 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

text3.gifMost 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)

text3.gifPerfect Protection

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

text3.gifWideRangeInput Voltage

Under drastic rise or drop of input voltage (±45%)

output voltage will be steady at ±2.5%

text3.gifExcellent Response Time

Response Time is extremely rapid and is within 1.5 cycle

text3.gifAVR 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)

text3.gifDelicate 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)

text3.gifTotal insulation between input and output

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

and high voltage pulse

text3.gifPerfect Protection

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

text3.gifWideRangeInput Voltage

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

text3.gifExcellent Response Time

Response Time is extremely rapid and is within 1.5 cycle

text3.gifViable Application

Input voltage 110V or 220V

Output voltage can have 110V/ 220V at the same time (2KVA and above)

text3.gifAVR 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)
