Hold target PF
Switches stages automatically as load and PF change.
Automatic power factor controllers that switch capacitor stages to hold a target power factor.
The APFC controller (power factor relay) is the brain of an automatic power factor correction panel. It measures power factor continuously and switches capacitor stages in and out to keep PF at the target — maximising correction while avoiding over-compensation.
We supply multi-stage APFC controllers/relays from ENTES, sized to the number of capacitor steps in your panel.
Switches stages automatically as load and PF change.
Controllers for small panels up to large multi-stage banks.
Over/under-compensation alarms, harmonics warning and metering.
We supply trusted principals — Secure, CG Emotron, MECO, ENTES, Metravi and Sonel — so you get the right, genuine product.
Tell us your load or application and we recommend the correct rating, class and options — not just what's on the shelf.
Fast dispatch across South Gujarat from our Surat office and warehouse, with support after the sale.
It continuously measures power factor and switches capacitor stages in or out to maintain the target PF, so correction tracks the changing load automatically.
It depends on your load steps and total kVAr — more stages give finer correction. Tell us your panel's capacitor steps and we'll match the controller.
Send your requirement or load details — we'll recommend the right apfc controller with a quote, usually within one business day.
