APFC Panels (Automatic Power Factor Correction)
MOBY APFC (Automatic Power Factor Correction) panels are precision-engineered to maintain a consistently high power factor (0.98 to 0.999 lag / unity) across fluctuating industrial electrical loads. Utilizing intelligent multi-stage microprocessor controllers and heavy-duty gas-filled self-healing capacitors with detuned harmonic filter reactors, our panels eliminate low power factor penalties and unlock substantial utility bill incentives.

Key Engineering & Operational Features
Why electrical consultants, industrial plants, and utility engineers specify MOBY APFC Panels (Automatic Power Factor Correction).
Eliminates Electricity Board Penalties
Ensures continuous power factor above the utility threshold (0.95), completely abolishing punitive penalties from DISCOMs like CESC, WBSEDCL, etc.
Generates Monthly Bill Rebates
Allows commercial and industrial consumers to achieve 0.98–1.00 PF, capturing statutory power factor incentive rebates of 2% to 7% on total monthly energy bills.
Reduces Peak kVA Billing Demand
Lowering reactive kVA reduces overall contractual demand charges, freeing up captive transformer and switchgear capacity for plant expansion.
Detuned Harmonic Filtering
Series-tuned 7% or 14% filter reactors prevent electrical resonance, absorb damaging 5th and 7th harmonics, and prevent capacitor swelling and premature failure.
Capacitor Duty Switching
Employs specialized contactors with inrush damping resistor wires that suppress violent capacitive switching transients, protecting upstream electronic equipment.
Real-Time Electrical Monitoring
Advanced digital controller displays Line Voltage, Load Current, Active Power (kW), Reactive Power (kVAr), Total Harmonic Distortion (THD%), and step status.
