SBW Three Phase Servo Motor Type Regulator
This is a three phase regulator series designed for industrial heavy duty use. It has a powerful servo motor and has a chain mechanism for sturdiness. The three phases are adjusted jointly. The normal input voltage is 150-260 volts phase to neutral or 260-460 volts between phases. The output is cut off if the output goes outside set safety limits. The regulator can be bypassed and direct connection between input and output is possible. The output voltage can also be adjusted manually. The regulator normally maintains 380 volts output phase to phase but this value can be changed from the control board if desired.
