Current sense transformers for up to 40 A
15 November 2017, Passive Components

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 windings. They provide reinforced insulation per UL 60950-1.

The components provide output feedback for load current measurement and control in switching power supplies and overload/short circuit protection. They are qualified to AEC-Q200 Grade 1 (-40°C to +125°C) standards, making them ideal for automotive applications like current measurement in traction motor and battery management systems. They are also well suited for use in 48 V vehicle systems. Other applications include aerospace power management systems, three-phase solar inverters, industrial motor controls and other applications requiring high isolation between the sense and output windings.

The CST2020 series is available with four turns ratios ranging from 1:70 to 1:300, and offers very low sense resistance (0,84 mΩ).
