The Fisher
Pierce Powerflex?/font> Low Profile Capacitor
Switching Controls Series 70A/80A are single function controls for VAr,
Current, Voltage, or Temperature applications. Var controls use potential
transformers and current input for reactive ampere sensing.The
controls utilize bandwidth control to simplify settings and prevent errors. The controls are packaged in a reinforced Lexan or aluminum enclosure. They can be mounted on a meter socket or bracket and are small and lightweight for easy installation. |
