RM Series with Dual Setting Controller
Intelligent Reactive Power Management – RM Series Dual Setting Controller
Description
- Intelligent RM Series P.F. Controllers are used for measurement and control of P.F. control units for central reactive power compensation. The P.F. measured by Neptune RM Plus is compared with the set values and in order to provide necessary compensation. P.F. Controller switches capacitor banks ON & OFF automatically. RM Plus is Single Phase CT Sensing micro controller relay, designed for above application in 144×144 case for flush mounting with rear plug-in connectors. Microcontroller based programmable RM Plus series relays are manufactured with 8 & 12 capacitor steps. It can work either in automatic or manual mode.
