INTRODUCTION
Precision Metal Clad Resistors are designed with four terminals to isolate voltage and current.
This enables very precise current measurement. These units exhibit a high load capacity as
well as excellent accuracy and low inductance. The simple four port Kelvin design and heavy
copper terminals ensure easy installation on large current bus bars. Applications include:
Battery manufacturing test jigs, current detection in precise power sources, constant current
sources, industrial power conversion circuits, HEVs, fuel cells and constant electronic loads
