500A 100mV dc current shunt Resistor
Product Description
NQQK’s 50mV and 100mV base-mounted current shunts are designed for measuring dc currents from 5A to 1200A. These precision shunts (+/-0.25% accuracy) connect directly to NQQK’s DCA5-20PC Series of dc ammeters. Installation is straightforward: simply connect the load circuit to the shunt’s threaded studs and the shunt’s mV Kelvin-outputs to the digital ammeter’s input terminals. All models feature a rugged phenolic base that provides 750V isolation to the shunt’s brass terminals, allowing for direct attachment to metal surfaces. A highly stable (+/-15ppm/°C) manganin sensing-element provides a wide -40 to +60°C operating temperature range. Please see the DCA5-20PC data sheet for additional ammeter-related information and detailed connection diagrams.
