Open-loop Hall Effect current sensors for precise DC, AC, and pulsed current measurement with galvanic isolation, exclusively PCB-mountable. Available in through-hole (-P), surface-mount (-SM), and digital PDM (-PW) configurations on a 3.87 cm² footprint at 12mm height. Analog variants provide a Vref-referenced voltage output for direct ADC interface with low offset and gain drift. Digital PDM variants integrate an onboard 2nd-order Sigma-Delta modulator delivering a PDM bitstream via 2-wire CMOS, RS422 Manchester, or LVDS Manchester interfaces. Factory calibrated; low power consumption.
Applications include AC variable speed and servo drives, DC motor drive converters, UPS, SMPS, welding power supplies, combiner boxes, and solar inverter DC-side MPPT current measurement.
