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.
