- R450 is analog Automatic Voltage Regulator with transistors
- Single or three phase voltage sensing with optional module
- Voltage regulation +/- 0.5% at steady state and constant speed
- Control by transistor means that the regulation quality is independant of applied load
- Suitable for high levels of vibration and harsh environments
