Electronics Engineering Supply Chain current sense transformer

COILCRAFT CST2020 Series current sense transformers sense current up to 40 Amps over a frequency range of 400Hz to 1MHz and provide 4000Vrms isolation voltage between the sense and output windings. Devices provide Reinforced Insulation per UL 60950-1. Products provide output feedback for load current measurement and control in switching power supplies and overload/short-circuit protection. Devices are qualified to AEC-Q200 Grade 1 (-40°C to +125°C) standards, making them suitable for automotive applications. Products are available with four turns ratios ranging from 1:70 to 1:300, and deliver low sense resistance (0.00084 Ohms).
