Product Education

What Is an APFC Panel?

An Automatic Power Factor Control panel, or APFC panel, improves the power factor of an electrical system by automatically monitoring reactive power and switching capacitor banks on or off in real time bringing the power factor closer to unity (1.0) and reducing wasted energy. As an automatic power factor controller built around a microprocessor brain, it removes the guesswork from manual correction.


Inside, a microprocessor-based automatic power factor control panel continuously measures the system's power factor and switches capacitor steps via contactors or thyristors as load conditions fluctuate. This dynamic adjustment, delivered by the automatic power factor correction system at the heart of the panel, keeps the power factor near 0.995, which reduces electrical losses, improves voltage stability, and lowers the reactive-power demand charges many utilities apply to facilities with poor power factor. For plants comparing options, our APFC panel price is built around the capacitor bank rating and switching device you actually need not a fixed, oversized catalog unit.

What Is an APFC Panel?
Problem Awareness

What Happens Without the Right APFC Panel

01

Utility penalty charges

Poor power factor triggers reactive-power demand charges that inflate electricity bills.

02

Voltage instability

Uncompensated reactive power causes voltage fluctuations that stress sensitive equipment.

03

Manual capacitor switching

Fixed capacitor banks without an automatic power factor correction panel over- or under-compensate as load changes

04

Equipment overheating

Excess reactive current increases I²R losses, leading to overheating in cables and transformers.

Capabilities

What Makes Burak Electric's APFC Panels Different

Built for the operating conditions of real industrial environments not just the test bench.

Automatic Capacitor Switching

Automatic Capacitor Switching (Dynamic Load Response): Automatically switches capacitor banks on and off, maintaining optimal power factor even as load conditions fluctuate — the core job of any apfc control panel.

Enhanced Protection

Enhanced Protection: Improves power factor and reduces electrical disturbances via a built-in automatic power factor control relay, safeguarding sensitive electronics.

Microprocessor-Based Control

Microprocessor-Based Control: Constantly analyzes the power system for precise, efficient capacitor switching the same logic used across our wider range of power factor panels and standalone power factor controller units

Energy Savings

Energy Savings: Minimizes wasted reactive power, translating directly into cost savings.

Customizable Tuning

Customizable Tuning: Configurable tuning frequencies to work effectively across various electrical loads, available on every apfc electrical panel we build. Ask about our apfc automatic power factor controller option for retrofitting existing capacitor banks.

How an Automatic Power Factor Control (APFC) Panel Works

The step-by-step operating sequence inside every Burak Electric APFC panel.

1

Power factor monitoring

The controller continuously measures the system's real-time power factor.

2

Reactive power calculation

The microprocessor calculates how much reactive compensation is needed.

3

Capacitor step switching

Contactors or thyristors switch capacitor banks on or off in steps to match demand.

4

Continuous adjustment

As load fluctuates, the controller dynamically re-tunes capacitor switching.

5

Protection monitoring

Built-in relays guard against overvoltage, undervoltage, and overcurrent throughout.

Common Questions

Frequently Asked Questions About APFC Panels

What is the difference between an APFC panel and a regular capacitor bank?
A regular capacitor bank provides fixed compensation, while an APFC panel automatically switches capacitor steps in real time to match fluctuating load avoiding both under- and over-compensation. This is also why most buyers searching for a power factor controller end up specifying a full automatic power factor control panel instead.
How much can an APFC panel reduce my electricity bill?
Savings depend on your current power factor and your utility's penalty structure, but correcting power factor toward 0.995 typically eliminates most reactive-power demand charges.
How many capacitor steps do I need?
Standard configurations offer 4 to 12 steps; 6 steps suits most mid-sized industrial loads. Higher step counts give finer control for facilities with highly variable loads.
Can an APFC panel cause harmonics issues?
Standard APFC panels with detuned reactors are designed to avoid resonance with harmonic-generating loads. Share your load profile and our team will recommend the right configuration.
What is the typical lead time for a custom APFC panel?
Lead time varies by capacitor bank rating and switching device selection. Share your project details and our team will confirm an exact timeline with your quote.
What standards do your APFC panels comply with?
Our APFC panels are ISO certified and CPRI approved, engineered to IEC 61439 and IS 8623 standards
Does Burak Electric export APFC panels internationally?
Yes Burak Electric manufactures and exports APFC panels to industrial buyers beyond India, alongside domestic project work.
What does an APFC panel cost compared to manual correction?
Final APFC panel cost depends on capacitor bank rating, number of steps, and switching device type. Share your facility's load profile and our engineering team will quote an apfc panel price alongside the expected payback from reduced demand charges.
Is an automatic power factor panel the same as an APFC panel?
Yes"automatic power factor panel" and "APFC panel" describe the same product. Whichever term you use, the apfc power factor correction logic inside is identical: continuous monitoring with automatic capacitor switching.
