DC current shunts

DC current shunts
Shunt resistors manufactured by DEIF are designed to convert direct current into a voltage measurement signal. The shunts are connected in series in the circuit and are used to expand the measurement range of DC ammeters.

Specifications:
  • Accuracy class: 0.5 (in the range -10 ... 15 ... 30 ... 55 ° C), according to IEC 51 and EN 60051
  • Measured current: from 1 to 2500 A
  • Immunity to interference (EMC): According to EN 50081-1 / 2 and EN 50082-1 ​​/ 2; CE marking for civil and commercial applications, light industry and industrial premises
  • Temperature Coefficient: 0.05% / 10C. The shunt is calibrated at 75% of In
  • Overload: <250A - 10 x In for 5 sec. 250А <… <2000А - 5 х In for 5 sec. > 2000A - 2 x In for 5 sec.

Transformers Transformers The simplest converter is a trans-former, transforming or converting one voltage into another voltage, for instance 440 V into 110 V.
Transformers have losses, as heat is produced during this conversion. The efficiency is usually between 90 and 98 percent, depending on size, a reason to avoid transform¬ers in power distribution systems
