Automatic Voltage Regulator for TAL alternators


The R150 automatic voltage regulator (AVR) for the TAL series of industrial alternators provides excitation current up to 6 A with excellent reliability. 

The R150 includes advanced protections such as over-excitation limitation and voltage sensing loss, and also features voltage droop for genset parallel operation.
