SINCRO B4 is an automatic analog voltage regulator AVR designed for 50/60 Hz brush generators.


Regulates the output voltage of a generator by controlling the field current. It has single phase detection. The voltage regulator controls and maintains the voltage constant.
A frequency measurement circuit continuously monitors the alternator output and provides underspeed protection at the excitation system output by reducing the output voltage proportionally to the speed below a presettable threshold. There is a manual adjustment for the factory setting of the sub-frequency (UF) roll-off point. This can easily be changed to 50 or 60 Hz with two dip switches.

Connection of a remote voltage potentiometer is provided, allowing the user precise control of the alternator output.


The AVR B4 includes:
- To the terminal block (9 terminals)
- A voltage trimmer
- A stability trimmer
- An underfrequency trimmer
- DIP switch for frequency selection. - Electrical protection with fuse.
The electronics are sealed with resin (it is a perfect protection against vibrations and humidity) and is RoHS compliant.
