20M20A100

Ram Meter Inc. DC (direct current) instrument shunts are used to extend the range of ammeters whenever the current to be measured is too large to be passed through the instrument - usually currents over 50 amperes. Therefore the shunt is a diverter which is used to "shunt" the majority of the current around the indicating instrument. The shunt is essentially a specially designed resistor which delivers a millivolt output (to a millivolt meter or instrument) in proportion to the current flowing through the resistor.

Features:

  • Available in ranges from 0.5A to 3500A+ (higher ranges available by special request)
  • 0-50 and 0-100 DCmV Standard Outputs
  • Portable, Bus-Bar and Commercial/Military Lightweight styles available
  • Portable type shunts come on insulating bases which can be fastened to any flat surface
  • Also available WITHOUT a base by special request

Adjustment Accuracy

Ram Meter Inc. shunts are adjusted to within +/-0.25% nominal value with an applied current that will not raise the temperature of the terminal blocks more than 50°F (10°C) with an ambient room temperature of 77°F (25°C) +/-2°.

Rated Accuracy

Commercial shunts up to 1,000 amps have an accuracy of +/-0.33%
Commercial shunts 1,000 amps and above have an accuracy of +/-0.5%
Commercial lightweight shunts have an accuracy of +/-0.6%
Military lightweight shunts have an accuracy of +/-0.6%

This allows for self-heating variation at the higher current values and variance in connections.

CUSTOM SHUNT DESIGN

We welcome the opportunity to work with you on your special design applications where other current, millivolt, size, accuracy or environmental conditions preclude the use of our standard catalog items. If this is the case, please fill out our Ram Meter Inc. Special Shunt Requirement Form or CONTACT US and one of our highly trained sales representatives will help you find a solution.
