Description
All our current shunts are calibrated to ± 0.25% accuracy at room temperature (20 °C, 68 °F).
Temperature drift of the measured voltage is typically 0.002% per °C (1.8°F).
They are manufactured to meet GSA federal CID-A-A-55524 specifications which supersedes military specification: MILS161B.
Note that for continuous operation in room temperature freely circulating air, the shunt should be operated at only 66% (2/3) of the "rated
current". E.g. a 500 Amp shunt is good for 333 Amps continuously.
You should keep the shunt's operating temperature below 145°C to prevent permanent change to its resistance. 90 °C (194 °F) on the
resistive strips is a good operating maximum to stay withing specification.
Shunts have a phenolic base with two holes for mounting screws. Terminal blocks are solid brass.
Size: 3.25" L x 1.75" W x 1.75" H.
Has 3/8" dia. bolt power terminals. 0.205" diameter mounting holes.
