Base Mounted Shunts Switchboard

General Details

Base Mounted Shunts Switchboard





Base Mounted Shunts Switchboard type are available with a range from 1 to 500 DC Amps. Standard Output of either 50 mv DC or 100 mV DC are available or custom outputs available as requested.

Base Mounted Shunts Switchboard type offer high accuracy at +/- 0.25 % and are very lightweight at 0.6 lbs each.

Typical applications include battery chargers, electroplating, heavy industry, mining, solar generators, and wind power.

Available options include Certificates of Calibration or Certificates of Conformance, if required.

Advantages of Direct current (DC) instrument shunts are that the units 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. The DC shunt, therefore, is a diverter which is used to “shunt” the majority of the current around the indicating instrument. Essentially, the DC shunt is a specially-designed resistor which delivers a millivolt output (to a millivolt meter or instrument) in proportion to the current flowing through the resistor.
