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.

Model	Current ratio	Winding ratio	Load resistance	Accuracy
H-DCT028	10(100)A/4mA	1:2500	20Ω	0.1Class
H-DCT008	10(120)A/4mA	1:2500	12.5Ω	0.1Class
H-CT027	1(10)A/2mA	4:2000	20Ω	0.05Class
H-DCT025	10(100)A/4mA	1:2500	20Ω	0.1Class

1.2,PCB mount (H-CT003 series) Core CT's are available for measuring currents from 0 to 150 Amps.

C

Model	Current ratio	Winding ratio	Load resistance	Accuracy
H-CT003A	5(10)A/5mA	1:1000	10Ω	0.2Class
H-CT003B	50A/50mA	1:1000	10Ω	0.2Class
H-CT003D-P	10(50)A/4mA	1:2500	0Ω	0.1Class
H-CT003D	10(100)A/4mA	1:2500	20Ω	0.1Class

1.3, Ring/ZERO(H-CT004 series) Core CT's are available for measuring currents from 0 to 5000 Amps.

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
