An APFC Panel (Automatic Power Factor Control Panel) is an electrical control panel used to improve the power factor of electrical systems by automatically switching capacitor banks in or out, depending on the load requirements. It helps reduce energy losses, avoid power factor penalties, and increase energy efficiency.

• Main Components of an APFC Panels

Component	Function
APFC Relay / Controller	Measures PF and triggers capacitor switching based on load demand

Cooling Fans	Maintain temperature inside the panel
Meters and Indicators	Display voltage, current, PF, etc.

• What is Power Factor?
Power Factor (PF) is the ratio of real power (kW) to apparent power (kVA).
A low PF leads to higher demand charges and inefficiencies in the electrical system.
Utilities often charge penalties for poor power factor (typically < 0.9 or 0.95).
• What is an APFC Panel?
An APFC panel monitors the power factor using a power factor controller and automatically switches capacitor banks to maintain the desired PF level. It eliminates the need for manual intervention and ensures optimized reactive power compensation.
• Working Principle
The APFC relay continuously monitors power factor using inputs from CTs and meters.
When the PF drops below the set value (e.g., 0.95), the relay signals contactors or thyristor modules to add capacitor banks.
When PF is too high or load reduces, the relay disconnects capacitors to prevent overcorrection.
This automated process ensures optimal power factor at all times.

VFD Panels are designed to control the speed and torque of electric motors by varying input frequency and voltage to motors. VFD Panels are used as energy saving devices as they adjust motor speed under no load conditions or as required by the process. Such energy cost savings are especially pronounced in variable torque centrifugal fan and pump applications where there is large power reduction for a relatively small reduction in speed. We design and manufacture a diverse range of VFD panels for varied applications (closed-loop and open-loop applications).

A VFD Panel (Variable Frequency Drive Panel) is an electrical control panel that houses a VFD (Variable Frequency Drive) used to control the speed and torque of AC motors by varying the frequency and voltage supplied to the motor.
