CS series CS1000 , CS1200 , Current transformer for working frequency more than 200KHz , switching power supply
Features:
1. Good voltage separation ability and insulation property
2. It is applicable for working frequency more than 200KHz
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℃, CS serires are main applied in high frequency switching power supply.
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.
