Open-loop Hall Effect current sensors for DC, AC, and pulsed current measurement with galvanic isolation, covering 6 to 250A RMS across PCB-mount, through-hole, surface-mount, panel-mount HO -P, HO-NP, HO -NSM, HO-S, HO-PW and HO -SW variants. Insulation test voltage up to 4300V; 8mm creepage and clearance; dedicated overcurrent detection pin on all models; factory calibrated.

Analog variants provide Vref-referenced output with low offset drift. Digital PDM variants integrate a Sigma-Delta modulator with 2-wire CMOS, RS422/LVDS Manchester, and 4-wire RS422/LVDS interfaces.  Advanced HO-NPPR models offer programmable ranges, adjustable offset and sensitivity, configurable overcurrent thresholds, and standby mode. Applications include AC/DC drives, UPS, SMPS, welding, and solar inverter MPPT.
