Current Transducer HLSR-P series
Open loop multi-range current transducer for electronic measurement of DC, AC, pulsed currents with galvanic separation between primary and secondary circuits. Features include voltage output, single +5 V supply, low power consumption, compact design for PCB mounting, factory calibration, and high bandwidth with a very low loss magnetic core. Advantages include an extremely low profile (h=12 mm), low footprint, low offset drift, and over-drivable Uref. Applications span AC variable speed and servo motor drives, static converters for DC motor drives, battery supplied applications, UPS, SMPS, welding power supplies, combiner boxes, and MPPT.
