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.
