Power-transformer designs minimize weight and cost based on three assumptions: (1) the power source is a sine wave, (2) the frequency is fixed, and (3) the voltage will not exceed a specified maximum.

Coilcraft’s new CST2020 Series current sense transformers sense current up to 40 Amps over a frequency range of 400 Hz to 1 MHz and offer 4000 Vrms isolation voltage between the sense and output ...
