SYSTEM OVERVIEW
The DynAmp LKAT Plus system is designed to accurately measure AC or DC current flowing
in a bus bar. Each system consists of a Measuring Head, a Metering Unit, and
multi-conductor cables.
The LKAT Plus Metering Unit consists of a power supply pc board and Main pc board
mounted together on a steel U-chassis. Input, output, and power connections are made from
outside the enclosure using panel-mount IP65 rated military-style circular connectors. Wiring
harnesses within the Metering Unit are terminated using 3.5mm and 5.08mm “Eurostyle”
connectors.
AVAILABLE ACCESSORIES
•
Summing / Totalizing multiple LKAT systems
A dedicated external module is available for totalizing/ summing up to 10 LKAT measurement
signals. This is typically used to provide a true ‘total’ current signal when multiple rectifiers
( with individual LKAT systems ) are connected in parallel to provide a higher total current.
•
LKAT-MUT Functional Test
This hand-held test set allows users to verify system operation and scaling as well as test
relay trip points and output signals in the field.
•
LKAT Metering Unit Tester ( LKAT MUT )
The LKAT MUT is a portable tester used to verify the functionality of Metering Units for all
versions of the LKAT family of products.

•
Input / output sensitivity
•
Trip point scaling
•
Trip relay contacts
•
Integrity of input / output harnesses and interconnections on Metering Unit
