APFCR / APFC Relay – Trinity Make

The APFCR (Automatic Power Factor Control Relay) is a KVAR-based controller designed for three-phase, four-wire systems with single-phase sensing. It controls up to 16 capacitor banks to maintain a near-unity power factor, while monitoring various electrical parameters.

✅ Key Features:

• Controls up to 6 to 16 capacitor stages

• Site-selectable modes: PF / FIFO / SFIFO / VAR

• Built-in display for Voltage (L-N), Current, and Power Factor

• Supports fast switching models

• Monitors VTHD & ITHD

• Flexible stage usage: Lower stages (4, 6) can be used in higher models (8, 12, 16)

• KVAR-based intelligent control for accurate capacitor switching

• Measures and displays key electrical parameters for system optimization

Ideal for industrial and commercial applications where precise PF correction, energy monitoring, and harmonic control are critical.

ACCUVAR – Advanced APFC Relay (Trinity Make)

• Available in 8 Stage/ 15 Stage/ 16 Stage

• Comprehensive 3-Phase Measurement: Monitors voltages, currents, PF, power, energy, THD, and harmonics (up to 15th order).

• Large 128×64 LCD Display: Bigger PF display for better visibility and readability.

• Intelligent VAR-Based Control: DSP-based control algorithm ensures precise capacitor switching based on reactive power (VAR), not just PF.

• 1% Load Sensing: Operates from as low as 1% load in FIFO & S-FIFO modes.

• Smart Features:

  • Auto CT polarity correction

  • Auto voltage phase sequence correction

  • Lead PF setting in FIFO & S-FIFO

  • Auto sensing (without capacitor CT)

  • HT/LT and CT/PT selection

• Auto-Sensing Capacitor Banks: No need for manual programming of C/K or stage sizes.

 

A compact, intelligent, and user-friendly solution for accurate PF correction and harmonic monitoring.

The NEWTON+ controls the automatic system for correction of the power factor. It is a KVAR based controller which controls up to eight capacitor banks optimally to achieve near unity power factor and also measures/calculates various electrical parameters. NEWTON+ is meant for use in three phase four wire electrical systems based on single phase sensing.

NEWTON+ displays Volt, Amps, system KW, system KVAR, system PF, THD & up to 7th ODD harmonics for Volt age & Current on 128x64 display.
