DynAmp LKAT

The LKAT Plus combines high current measurement and reverse or overcurrent protection into a single rugged system. Based on innovative OLOPTM technology which is designed to accurately and reliably measure uni- and bi-directional DC and AC bus currents up to 100kA. The LKAT Plus consists of a two-piece measuring head, constructed to match the dimensions of the measured bus, electronics enclosure, mounting hardware and interconnection cables.

Application

The LKAT Plus is particularly well suited to measure power rectifiers outputs for control and protection purposes in electro-chemical processes such aluminum, chlorine, copper, manganese, titanium, zinc, electroplating, etc.

 

Key Features

True bi-directional performance. Ideal for difficult magnetic applications.

Setpoint relay can be used for reverse or overcurrent protection of rectifiers.

Extremely compact with excellent environmental specifications for installation flexibility, inside or outside.

System includes Accuracy Diagnostics.

Optional digital display can be scaled for DC or RMS.
