About the Product
The Lauritz Knudsen EasyLogic APFC Relay CS91050 (EtaUltra Series) is a high-precision Automatic Power Factor Correction (APFC) controller specifically designed for three-phase electrical systems requiring advanced monitoring accuracy, balanced compensation, & reliable energy optimization. Equipped with three Current Transformer (3 CT) inputs & 8-step capacitor bank control, this intelligent relay delivers accurate phase-wise power factor correction through contactor-based switching technology, making it ideal for industrial & commercial applications with varying load conditions.
The relay continuously monitors power factor, reactive power demand, & load conditions across all three phases independently. Unlike conventional single-CT APFC relays, the 3 CT configuration enables individual phase measurement, allowing the controller to respond more accurately to real-world load imbalances & varying phase conditions. This results in improved correction accuracy, enhanced system stability, & more efficient capacitor bank utilization.
By continuously analyzing power consumption & reactive power requirements, the controller automatically switches capacitor stages ON or OFF to maintain the desired power factor. This helps reduce electricity penalties imposed by utilities, minimizes power losses, improves energy efficiency, & ensures optimal electrical system performance.
The 8-step capacitor switching configuration provides fine correction granularity & smooth compensation. The staged switching approach allows the relay to make precise adjustments according to changing load conditions, reducing unnecessary switching operations while maintaining stable power factor levels across the network.
The 3 CT measurement system provides several important advantages, including phase-wise load analysis, enhanced performance in unbalanced load conditions, improved correction precision, & better protection against phase imbalance issues commonly encountered in industrial installations.
Designed for contactor-based switching systems, the relay provides reliable & cost-effective performance for applications with conventional switching requirements. It combines dependable operation with easy integration into existing APFC panel designs & capacitor bank installations.
The controller features a user-friendly interface that simplifies configuration, monitoring, & maintenance. Users can easily configure operating parameters including target power factor, capacitor stage sequence, switching delays, alarm functions, & protection settings according to application requirements.
Real-time monitoring & intelligent control capabilities help prevent issues such as overcompensation, uneven phase correction, excessive capacitor switching, & unstable power factor conditions. This contributes to increased equipment life, improved energy efficiency, & enhanced system reliability.
As part of the Lauritz Knudsen EasyLogic EtaUltra product range, the APFC Relay CS91050 combines advanced three-phase monitoring technology, industrial-grade reliability, & simplified installation, making it ideal for panel builders, system integrators, OEMs, facility managers, & industrial operators.
The compact panel-mountable enclosure enables easy installation inside APFC panels, capacitor bank systems, electrical switchboards, & main distribution boards.
This APFC relay is an ideal solution for applications requiring accurate three-phase power factor correction, energy optimization, improved power quality, & reliable long-term operation in industrial electrical systems.
