Capacitor control - capacitor switching controllers for 2 or 3 step configurations

The Fisher Pierce Powerflex Two and Three Step Capacitor Switching Controllers offer the most flexible and efficient method of capacitor switching. The controllers are intended for use with multiple capacitor racks found in substation applications.

The controls can be purchased in either 2 or 3 step configurations, measuring Var, Voltage, or Line Current. The control operates starting with the first step (module) and activates consecutively after a fixed time delay. The sequence is reversed when opening capacitors.
