The etaSMART APFC Controller rectifies power factor automatically through the connection and disconnection of capacitors. Equipped with a specially formulated optimisation program embedded in its microcontroller, it guarantees precise power factor regulation at the designated set point, ensuring smooth and uninterrupted operation.
Introducing the etaSMART APFC Controller from Lauritz Knudsen – a smart, user-friendly relay that automatically controls power factor by intelligently managing capacitor switching. Engineered for reliability in diverse electrical systems, it offers effortless installation with auto-programming capabilities, site-selectable CT secondary options (1/5A), and site-selectable 2/4 quadrant operation for industries with or without solar plant.
Lauritz Knudsen etaULTRA APFC Controller – A 3 CT APFC Controller for accurate phase-wise monitoring, individual harmonics measurement up to the 31st order, and advanced optimization algorithms, etaULTRA ensures hunt-free operation, superior power quality, and optimal capacitor bank switching via contactors or thyristors. With built-in MODBUS RS-485 communication, dual power factor settings for mains/DG applications, and cascading support for panels exceeding 16 steps, it delivers unmatched reliability and efficiency in unbalanced or harmonic-rich systems.
