AVR MX450 Automatic Voltage Regulator for Stamford Diesel Generator


Availability: 20 in stock

Original Option
**Genuine Alternative:** This AVR MX450 is a high-quality aftermarket replacement for the original Stamford voltage regulator.

Sharing is caring!


AVR MX450 is a half-wave phase-controlled Thyristor type Ac regulator and forms parts of the excitation system for a brush-less Electric generator.

Positive voltage build up from residual level is ensured by the use of efficient semiconductors in the power circuitry of the AVR.

The AVR is linked with the main stator windings and the exciter field windings to provide closed loop control of the output voltage with load regulator of +/-1.0%.
