- Description
The long-life shunts are used to expand the current measuring range of moving coil ammeters for the reliable displaying and further processing of direct currents, especially at high rates of up to 15 000 A.
The direct current flowing through the shunt generates a proportional voltage drop which, for example, can be displayed by means of a moving coil meter connected in parallel or be further processed electronically.
The shunts manufactured by us comply with EN 60051-1, EN IEC 60051-8 and DIN 43703.
The accuracy is 0.5% relative to the nominal value. In addition, shunts with an increased accuracy of 0.2% or 0.1% can be realised on request. The rated currents are in the range of 1 A to 15,000 A. Shunts are manufactured in three different designs, depending on the nominal current.
Up to 25 A, the shunts are always mounted on an insulating base which can be mounted on a 35 mm DIN rail or by means of screw fixing. Above 25 A, an insulating base is optionally available for SHU-B1, as well as for some current ranges in SHU-B2.
