Product Description

1,About Current transformers series

Current transformer provide a simple, inexpensive and yet accurate means ofsensing 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.

1.3, Ring/ZERO(H-CT004 series) Core CT's are available for measuring currents from 0 to 5000 Amps. Jiaxing Haihan Electron Co.,LTD supply to High ratio vertical current transformers are avalable in a wide range of sizes and materials to meet any AC current sensing needs,our general purpose designs are made from the highest quality silicon steel cores available,and meet most of the common AC current measurement needs, magnetics offers DC immune models that are designed to provide sensing of AC current where DC offsets also exist,all products are offered in standard sizes,with the most popular turns rations.

1.4, Clamp on Core CT's(H-CT007 series) are available for measuring currents from 0 to 5000Amps. Jiaxing Haihan Electron Co.,LTD supply to High ratio vertical current transformers are avalable in a wide range of sizes and materials to meet any AC current sensing needs,our general purpose designs are made from the highest quality silicon steel cores available,and meet most of the common AC current measurement needs, magnetics offers DC immune models that are designed to provide sensing of AC current where DC offsets also exist,all products are offered in standard sizes,with the most popular turns rations.
1.5,BH (H-CT021 series) Core CT's are available for measuring currents from 0 to 6000 Amps. Jiaxing Haihan Electron Co.,LTD supply to High ratio vertical current transformers are avalable in a wide range of sizes and materials to meet any AC current sensing needs,our general purpose designs are made from the highest quality silicon steel cores available,and meet most of the common AC current measurement needs, magnetics offers DC immune models that are designed to provide sensing of AC current where DC offsets also exist,all products are offered in standard sizes,with the most popular turns rations.

 

2,About latching relay.

 

3,About 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
