APFC Panel
APFC panels are used in commercial buildings and industries where there is fluctuation in voltage and power supply, which can damage machinery, cooling plants and other equipment.

APFC Panel
APFC panels are used in commercial buildings and industries where there is fluctuation in voltage and power supply, which can damage machinery, cooling plants and other equipment.
Fixed loads can be corrected with fixed capacitors, but varying loads need a mechanism to switch capacitors in and out as the demand changes. An Automatic Power Factor Correction panel does exactly this — monitoring the power factor continuously and switching capacitor banks in steps through a microprocessor-based relay.
The result is a power factor held close to unity, lower kVA demand, reduced line losses and freedom from utility power-factor penalties.
Key Features
- Microprocessor-based APFC relay
- Capacitor-duty contactors and HRC / MCCB protection
- Detuned reactors for harmonic-rich loads
- Step-wise automatic capacitor switching
- Reduces kVA demand and PF penalties
- Forced ventilation for capacitor life
