P.F. Compensator- Automatic P.F. Correction Series - 12.5 KVAR to 100 KVAR
Features :
NAAC P.F. Compensator series the power range goes from 12.5 kvar to 100 kvar. They are designed for small to medium load networks. They are highly reliable, cost effective solution for maintaining high network power factor.

They are ultimate solution for compensation of unbalanced loads. The compensation is released by measuring the reactive power of the system, through 3 CTs from all 3 phases. This makes it best suited even for most unbalanced loads apart from balanced loads.

They come equipped with following outstanding features:

  • Incomer TP MCCB 35kA

  • Micro processor based Neptune Phasetrac range of 3 phase P.F. Controller

  • Inbuilt 3 phase Analyzer

  • Compact wall mounting series with zinc passivated side clamps
