Current Detection Transformer "CST2020 Series"
Low loss and high inter-layer insulation with extremely low DCR! Capable of handling a wide frequency range from 400Hz to 1.8MHz, making it suitable for high-capacity power supplies.
We would like to introduce the current detection transformers from Coilcraft, the 'CST2020 Series.' These transformers are suitable for high-capacity power equipment, featuring low loss and a maximum detection current of 40A, with an inter-layer insulation voltage of 4000V, certified to UL60950-1. We offer four models: the "CST2020-070L" with a turns ratio of 1:70, the "CST2020-100L" with a ratio of 1:100, the "CST2020-200L" with a ratio of 1:200, and the "CST2020-300L" with a ratio of 1:300. 【Features】 ■ Extremely low DCR for low loss: The DCR of the detection winding is 0.84mΩ, indicating low resistance. ■ High inter-layer insulation voltage: The inter-layer insulation voltage between the primary and secondary windings is 4,000V (for 1 minute), providing high insulation. ■ Compact with high current capacity: Maximum detection current: 40A. ■ High operating temperature: Operating ambient temperature range of -40℃ to 125℃. ■ ROHS compliant. ■ Small footprint: 2cm x 2cm x 2cm. *For more details, please refer to the PDF document or feel free to contact us. *An English version of the catalog is available for download.
