WT-3GP Engga Automatic Voltage Regulator

About this part

Sensitive loads such as computers, inverters and motor drives depend on a steady voltage. The regulator is a small, inexpensive board that protects everything downstream of the generator.

Features

• Power input is between 70 to 140 Volts ac
• Sensor detected between 220 and 480 Volts ac
• Maximum output in dc is 10 Amps at 125 Volts
• Adjustment rate is better that 0.5
• Weight is 1 kg
• Size is 20 by 16 by 6 centimetres

When to replace it

• Output voltage that is too high, too low or unstable
• No output voltage although the engine runs normally
• Lights flickering or voltage dipping as loads switch on
• A burnt or damaged board after a lightning strike or short

Before you order

Match the AVR to the alternator: sensing (single or three phase), excitation type (brushless or brush type), supply voltage and the physical mounting all have to suit. Note the wiring before disconnecting the old regulator.

If the old part has no readable number, send us a clear photo with the engine or alternator nameplate and we will identify it before you buy.
