Applications:
Continuous AC current monitoring in switched-mode power supply
Overload and short-circuit protection
Current measurement in traction motor and battery management systems in conventional and xEV (EV, HEV, FCEV) vehicles.
Can also be used in 48 V vehicle electrical systems.
Notes:
Inductance measured between secondary pins at 100 kHz, 0.1 Vrms, 0 Adc.
Primary current of 20 A causes less than 25°C temperature rise from 25°C ambient.Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
Terminating resistance (RT) value is based on 1 Volt output with 20 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation: RT (Ohms) = Vout × Nsec / Iin.
500 Vrms, 1 minute isolation (hipot) winding to winding.
Many differennt kinds of structure and style for your selection.
