Coilcraft’s has introduced a series of current sense transformers, operating up to 40A over 400Hz to 1MHz, and offering 4,000Vrms isolation voltage between the sense and output windings, using insulation reinforced to UL 60950-1. To minimise power loss, the resistance of the sense coil is very low: 840μΩ in all versions of the series, dubbed CST2020. ...
