Applications
When to consider 1R20 Series
Consider 1R20 Series when the charger design needs digital output, built-in self-test function, 5v power supply. It is intended for applications such as ac ev charging stations, mode 3 ev chargers, three-phase 22kw ac charging systems. Before freezing the design, confirm the conductor arrangement, available space, controller interface, target compliance tests, and trip behavior against the datasheet.
Integration and model comparison
EVsense models differ in mechanical format, aperture and conductor routing, transformer integration, and the intended charger platform. Use the specifications above as an initial filter, then compare this model with the complete product range. For a reliable recommendation, send a PCB drawing or space envelope together with rated current, target market, and required sample schedule.
