ΔAbout Manganin shunt.
Manganin shunt provide an accurate DC millivolt signal to drive ammeter indicators, overload protection and control devices, expecially for higher AMP. The shunts supply voltage drop proportional to DC current which is measured and indicated by moving coil meter with dial calibrated in AMPS

Company Information
Jiaxing Haihan Electronic Co., Ltd was established in 2011, We are a professional in designing and manufacturing two series products.we supply spare parts for electricity meter, such as current transformer, stepper motor counter, manganin shunt, magnetic latching relay, single-phase or three-phase cases, DIN-Rail single-phase energy meter or DIN-Rail three-phase energy meter
1,About Current transformers series
Current transformer provide a simple, inexpensive and yet accurate means of
sensing current flow in power conductors. They are available in 5 basic configurations:
1.1,Three phase and single phase energy meter CT's are available from measuring currents 0-120Amps.
1.2,PCB mount (H-CT003 series) Core CT's are available for measuring currents from 0 to 150 Amps.
