LEM HLSR-P Series Current Transducer
The LEM HLSR-P series is an open-loop multi-range current transducer designed for the electronic measurement of DC, AC, and pulsed currents. It provides galvanic separation between the primary and secondary circuits, featuring a voltage output and single +5 V supply. Its compact, low-profile design is ideal for through-hole PCB mounting, offering high bandwidth and low power consumption. Key advantages include an extremely low profile (h=12 mm), low footprint, low offset drift, and over-drivable Uref. Applications include 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 applications, combiner boxes, and MPPT systems.
