etaSMART

Overview

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.

Features

Available upto 16 steps
Space-saving. Compact size of 96 x 96 mm for controller upto 8 steps
Site Programmable CT Secondary 1A/5A
Automatic detection of CT polarity saves time and effort.
etaSMART detects the CT reversal and automatically corrects it
Site selectable 2 or 4 quadrant operation for industries with or without Solar plants

Benefits

Improved System Efficiency — Optimizes overall power quality, enhances equipment performance, and supports compliance with standards, leading to longer lifespan for motors, transformers, and other loads.
Easy Installation and Setup — Includes auto-programming (AUTOSET) function, site-selectable CT secondary (1A or 5A), and automatic CT polarity detection/correction, saving time and reducing wiring errors.
Versatility for Modern Applications — Supports 2-quadrant (conventional) or 4-quadrant operation, ideal for sites with or without solar integration, handling power export scenarios effectively.
Fast Response Options — Dedicated thyristor-switching models enable zero-crossing switching for rapid correction in dynamic loads, reducing transients compared to contactor-based systems.
Compact and Reliable Design — 96x96mm flush-mount size, suitable for balanced loads with low fluctuations; available in up to 8 steps for contactor switching.
