Current Transducer HLSR-P series
The HLSR-P series are open-loop, multi-range current transducers with voltage output, designed for the electronic measurement of DC, AC, and pulsed currents. They provide galvanic separation between the primary and secondary circuits, featuring a compact design for through-hole PCB mounting, single +5 V supply, and low power consumption. These transducers are factory calibrated and offer a high bandwidth with very low loss magnetic cores. Key advantages include an extremely low profile (h = 12 mm), low footprint, low offset drift, and over-drivable Uref. They are ideal for applications such as AC variable speed and servo motor drives, static converters for DC motor drives, battery-supplied applications, Uninterruptible Power Supplies (UPS), Switched Mode Power Supplies (SMPS), power supplies for welding, combiner boxes, and MPPT systems.
