PFC2-50kVAr 75A 415V

Description

The PFC2 Series Power Factor Switches provide precise and efficient switching for three-phase capacitive loads, enhancing power factor correction and reducing energy waste. Using the two-leg control technique, these controllers offer optimised capacitor switching with minimal inrush current. The PFC2 30kVAR & 50kVAR models feature integrated semiconductor fuses, an automatic resetting temperature trip, and fan cooling (on the 50kVAR model).

Key Features

✔ Enhanced Power Factor Correction – Optimises electrical efficiency and reduces reactive power.
✔ Low Inrush Current – Eliminates high start-up currents for capacitor banks.
✔ Rugged & Reliable – High-speed semiconductor fuses and enclosed panel mounting.
✔ Automatic Overtemperature Protection – Trips at 90°C and resets at 85°C.
✔ LED Status Indicators – Monitor power, faults, signal, and capacitor discharge.
✔ Multiple Control Options – Accepts 8-24V DC signals for seamless integration.
✔ Alarm Relay Function – Voltage-free relay for real-time fault detection.
✔ 50kVAR Fan Cooling – Automatically activates at 55°C to ensure longevity.
