Description :
Highly accurate manganin re-sistance d.c. shunts. When acurrent is passed through theshunt, a proportional millivoltoutput is produced.
Application :
VEPL VSH-L Shuntsare used for measuringcurrent in D.C. applicationsby connecting them tomoving coil panel meters,D i g i t a l m e t e r s o ro t h e r m e a s u r e m e n tdevices.These Shunts canalso be used in controldevices such as powersupplies and batter ychargers or for overloadprotection.
VEPL designed lightweight Shunts to catterg e n e r a l i n d u s t r i a lapplications.
VEPL manufactureand supply Shunts as perIS1248, available in VSHseries and details will beprovided on customerrequest.
