C AUTION :
Megger and high potential test equipment should not be used.
Incorrect use of such equipment could damage components contained in the regulator.

1. APPLICATION
2. FEATURES :
2.1. Available for low resistance exciter filed.
2.2. Under frequency protection circuit.
When the generator frequency drops below the set point, generator output voltage is decreased with
the curve proportional to the frequency.
2.3. Over excitation
When the generator excitation field voltage exceeds 85Vdc, AVR output shut down to protect the
generator winding coil from burning out.
2.4. Starting engine generator set, if the residual voltage remains on the stator winding of generator,
AC output voltage is built up rapidly.
2.5. Durable under dust, damp and vibration.
2.6. Response time, below 25ms(1.5cycles)

AUTOMATIC VOLTAGE REGULATOR
(MODEL : AVR-126)
AVR 125 is voltage regulator to control brushless generator output by regulating
the current into the generator exciter field.
