The Controller

Switching module

The switching module is comprised of solid-state switching elements that provide reliable, high-speed transient-free
operation. Single, double or three-phase electronic switches, SCR/SCR or SCR/diode are used for each capacitor group.
Switching modules are specically selected for each equalizer system based on the number of overall capacitor groups,
current requirements and voltage rating.

Cabinet Design

Each equalizer system IP20/NEMA1 cabinet is made of steel sheet, with an epoxy powder coated gray (RAL 7032).
