EVR106 (AVR) is a generator automatic voltage regulator based on half-wave phase-controlled rectifier excitation principle. The device that stabilizes the output voltage of the alternator by adjusting the excitation current of the generator. Used as auxiliary windings, phase power supply as the excitation power generator. With high stability, fast response, easy installation and maintenance features.
1, S1, S2 for the current compensation input, and the machine, the access ratio is In / 5A, the capacity of 5VA adjustable current transformer (CT) output.
2, A1, A2 for the analog voltage regulator input, can be connected to an external ± 5Vdc adjustable voltage source.
3, if the need for remote voltage adjustment, can be in VR1, VR2 can be connected between a 10 ~ 100KΩ / 1 ~ 2W potentiometer, otherwise, must be shorted!
* Adjustable soft start circuitry is included to provide a smooth controlled build up of generator output voltage.
