• Compact wall mounting series for small to medium industries.
• Available upto 1000 KVAR rating.
• Suitable for both balanced and unbalanced load.
• Advanced 3 phase controller with inbuilt load analyzer.
• Axial flow fan controlled through thermostat.
• Upto 3 year warranty with long life LL-10 Capacitors.

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 Controller
• Inbuilt 3 phase Analyzer
  
• Compact wall mounting series with zinc passivated side clamps
• Front louvers with Axial flow fan and thermostat
• Heavy duty specially designed Neptune capacitor duty contractors with high thermal current withstand capacity
• MCBs for control circuit protection
• HRC fuse or MCB (Series-D) for backup protection of capacitor banks
• High electrolytic grade aluminium Busbar installed on SMC TP supports
• Discharge resistors (MOR)
• Standard 1 year warranty with NSL-10 Capacitor or 3 year warranty with long life LL-10 Mono 16 Capacitors
• Powder coated - RAL 7035, Structure finish
