PRODUCTS - DC Shunts
Shunts are separately mounted units used for extending measurement of currents beyond the available limits of self contained DC ammeters.
EIC shunts are designed for use with standard 50 ,75 , 100 millivolt panel and switchboard meters or recording instruments. The face of the instrument is calibrated in terms of the ampere rating of the shunts. The millivolt drop of the shunt is adjusted at the factory to within +/-0.25% acccuracy. For continous operation, it is recommended that shunts are not run at more than two thirds the rated current under normal contitions of use as per AIEEE standards.
Where possible all shunts should be mounted on the grounded side of the circuit. Panel mounted shunts with insulated bases must be mounted on the grounded side of circuits above 750 volts.
For typical applications, choose from the following list. Place your order now !
SPECIFICATIONS
'EIC' make D.C. Shunts is made of very high precision stable imported Manganin wire which is silver soldered to Gunmetal terminal blocks for zero-resistance contact. Temperature rise and Dimensions is within limit specified in IS 1248. Standard pair of leads, each one meter length, is supplied with each shunts. Shunt upto 30A coan be supplied with Bakelite mounting strip.
