FEATURES

Current shunt resistors are low resistance precision resistors

used to measure AC or DC electrical currents by the voltage

drop those currents create across the resistance. Sometimes

called an ammeter shunt, it is a type of current sensor.

2 or 4 ports available

Tight Tolerance of

±1% and Tight TCR of ±100ppm

APPLICATIONS

Current Measurement of AC or DC electrical currents

RV battery monitor and battery chargers

Marine battery monitor and battery chargers

Golf Cart, Wheelchair, Electric Bike batteries & chargers

Digital panel meter Ammeter

Solar Power, Wind Power generators batteries & chargers

Electroplating and metal plating Amp Hour measurement

Hand Radio & Amateur Radio base station equipment,

battery monitoring and chargers
