Product Description:

Kf308a2 automatic voltage regulator (AVR) is a sealed electronic device specially designed for supporting AC brushless generator. AVR realizes the automatic regulation of generator output voltage by controlling the excitation current of alternator.

Product parameters:

Power input: fundamental / harmonic / PMG, maximum 240V;

Maximum excitation voltage output: 200V / 12adc / 10s;

Detection voltage input: 230 / 400VAC;

Low frequency protection 50 / 60Hz optional;

Generator field resistance ≥ 5 Ω;

Steady state voltage regulation rate ≤± 0.5%;

Voltage regulation range ≥ 15%;

Minimum remanence starting voltage ≥ 5V / 30Hz;

S1 S2：CT：0-1A/AC；

R1 R2: voltage fine adjustment ± 12% when external potentiometer 1K Ω / 1W:

A1 A2: voltage change of ± 0-10% when external ± 0-1vdc is connected;

Working environment temperature: - 40 ℃ ~ 65 ℃;

Precautions for use:

The installation, connection and inspection shall be carried out by personnel with professional knowledge, and the regulator shall be installed in the generator or in a place easy to be touched by others. Do not touch the regulator during operation to avoid dangerous accidents.
