Voltage Regulation & Power Quality

Servo voltage stabilizers, tap-changing stabilizers, voltage controllers and servo controller cards for supplies that vary outside the range connected equipment accepts, up to 500 kVA.

Voltage regulation equipment keeps the voltage at the load within the range that equipment is designed for, or sets an adjustable voltage for a process. The family covers servo voltage stabilizers for continuous correction, tap-changing stabilizers and variable-transformer voltage controllers, and the servo controller cards that sit inside a stabilizer. Each unit is rated against the connected load, the recorded supply conditions and the installation, single phase or three phase, up to 500 kVA.
