Close loop hall current sensors is a new generation of current sensor which applies hall effect principle, can measure direct current, alternating current, pulse and current of various irregular wave forms in electrical isolation conditions. Higher accuracy and linearity, short responding time and wide frequency band make it widely used in current monitoring devices, high current protection and other fields. The product has many other advantages: firm structure, low power consumption, small size, light weight, long lifetime, easy installation, vibration resistance, water vapor proof and dust proof, which assure convenient and reliable usage. And users can define the rated primary current and secondary rated output based on actual demand.
Rated output 25 to 400ma hall sensor for measurement
Description:
Current transformer mainly used in all kinds of electricity meter such as energy meter, water meter or electricity meter. We have current transformers both with and without DC immune.
