LT Power Factor Correction Panel

State-of-the-art LT Power Factor Correction Panels are available as APFC, RTPFC & Hybrid varieties.

LT Power Factor Correction Panel

Our LT product range covers every mode of reactive power correction at low voltage: fixed compensation, automatic contactor-switched APFC, ultra-fast thyristor-switched RTPFC, and hybrid panels built for harmonic protection — giving you the right solution for every load type and site condition.

Cospower LT Power Correction Panel Products

Automatic . Contractor

LT APFC Panel

Contractor-switched automatic panel that steps capacitors in and out as load varies. Suited for moderate load fluctuations requiring economical automatic correction.

Automatic . Thyristor

LT RTPFC Panel

Thyristor-switched for near-instantaneous response--ideal for rapidly fluctuating loads in steel rolling mills, hospitals and other sensitive enviornments where contractor switching is too slow.

Automatic . Hybrid

Hybrid Panel

Hybrid panels combining contactor and thyristor switching in a single panel to handle both stable and rapidly fluctuating reactive loads, delivering the precision of thyristor response where it matters and the economy of contactor switching where it doesn't.

Key Benefits

LT APFC PANELS (Low Tension Automatic Power Factor Correction)

For industries and commercial buildings at 415/440 V

Automatically switches capacitor banks in and out based on real-time load, keeps PF consistently high
Prevents PF penalty from electricity boards, direct savings on monthly bills
Reduces current in cables and switchgear, extends life of electrical equipment
Improves voltage levels at load end, resulting in better equipment performance
Suitable for varying loads like motors, welding machines, air compressors
Uses a microcontroller-based relay for fast, precise and reliable switching

LT RTPFC PANELS (Real Time Power Factor Correction)

For highly dynamic and rapidly changing loads

Ultra-fast response that corrects power factor in milliseconds, unlike contactor-based APFC
Uses thyristor switching instead of contactors; no wear and tear, longer life
Ideal for fluctuating loads like arc furnaces, rolling mills, and frequent motor starts
Eliminates transients and switching surges that normal APFC panels cause
Reduces voltage fluctuations, ensuring a stable supply to sensitive equipment
Best choice where load changes every few seconds

LT HYBRID APFC PANELS (Contactor / Thyristor Switching + SVG)

For loads with mixed stable and dynamic reactive demand

Combines contactor and thyristor switching in one panel, contactor steps handle stable base load, thyristor steps respond instantly to rapid fluctuations
Best of both worlds which is the economy of contactor switching where load is steady, precision of thyristor response where load is fast-changing
Reduces total panel cost compared to a full thyristor solution, without compromising response speed where it matters
Eliminates switching surges on dynamic load steps while maintaining reliable correction on stable steps
Ideal for facilities with mixed load profiles, stable motors running alongside arc furnaces, rolling mills, or frequent-start equipment
Single panel solution that simplifies installation, reduces panel room footprint, and lowers overall system complexity
