High Performance Power Factor Controller Relay with Thyristor Controlled Reactor Function

PFCS24.TCR is designed for compensation of balanced or unbalanced, rapid changing loads. Thanks to thyristor controlled reactor feature, it has ability for compensation of more sensitive loads.

*PFC24 TCR relay is an automatic power factor control relay designed for switching three phase, di-phase and single phase shunt capacitor and reactor banks. 

*PFC24 TCR, at the same time can control delta or star connected thyristor controlled reactor (TCR) modules. The steps to be switched can be introduced to controller automatically or manually. Operator determines the PFC target by setting the target power factor or target reactive power. With the aid of a digital input, relay can operate according to one of two target power factors or target reactive powers.
*PFC24 TCR also operates as a power analyzer. Grid voltages, line currents, active, reactive and apparent powers for each phase and total, power factors, energies, frequency, voltage and current harmonics, voltage and current waveforms can be monitored on LCD display. The operating time and switching count of each step are recorded and can be monitored.
*The relay measures the inner temperature. For panel cooling, a fan can be controlled by a dry contact of the relay.
*The relay has adjustable overcurrent, overvoltage, undervoltage, harmonics and temperature protection.
*PFC24 TCR is used with thyristor switched applications and optionally with contactor switched and hybrid applications.
*With Modbus RTU communication protocol, monitored parameters can be remotely accessed and relay settings can be changed.
*Automatic connection correcting and automatic step identification features make quick installation possible.
