Reactive Power Compensation Controller in Pakistan

The  Reactive Power Compensation Controller is a smart step power factor (APFC) relay that maintains target cosφ and reduces penalty charges in commercial and industrial panels across Pakistan.Setup is straightforward: set CT ratio, target PF, switching mode, and delays using the front keys and clear display.

The  supports 230/400 VAC, 50/60 Hz systems and provides relay outputs to drive capacitor contactors or thyristor modules. Status LEDs and alarms make diagnostics fast.

Features:

• 6‑12 step automatic power factor control
• Quick setup: CT ratio, target cosφ, delays
• Optimized switching reduces hunting and wear
• Protections: O/V, U/V, step inhibit; harmonic lockout (model dep.)
• Bright display, status LEDs; panel‑mount 96×96 mm

Specifications:

• Models: PFR-6, PFR-12
• System: 3‑phase, 230/400 VAC, 50/60 Hz
• Setpoint: target PF ~0.80–0.99 (lead/lag selectable)
• Mounting/Cutout: 96×96 mm; cutout ~92×92 mm; optional RS‑485 (model dep.)

Uses:

• APFC capacitor banks in LV panels
• Shopping malls, hospitals, office towers
• Manufacturing plants and workshops
• Cold storage, HVAC chillers, elevators
• Diesel/utility mains (consult for generators)
