CT10 series CT10B-2(12)A/2mA Class 0.2 Current transformer With high permeability permalloy core, excellent linear performance, small size for working frequency 50-400Hz , energy meter, power transducer, RTU, etc
Features:
1. Good voltage separation ability and insulation property
2. It is applicable for working frequency 50-400Hz
3. With burnt-resistant PBT case and epoxy resin, current transformer can reach insulation resistance of 500VDC ≥100mΩ, electrical strength 3000VAC,1mA 60S.
4. Under the ambient temperature -25℃ ~75℃, CT07 serires are main applied in RTU, power transducer, electrical monitoring meter, power meter and all sorts of controlling devices.
5. With high permeability permalloy core, excellent linear performance, small size; while by lamination silicon stell core, huge current load and low price.
For our current transformers, which are produced by using high permeability permalloy core or good quality laminated silicon steel core, inflammable epoxy resin and case with our high precision toroidal winding machine & current transformer testers, steady quality and reliable safety, are widely applied in electronic energy meter, power transducer, RTU, electronical monitoring meter, power factor compensator, digital meter, motor control, industrial control system, electrical meter equipment, etc.
