Open Loop Current Transducer LEM HLSR10-P Multi Range Voltage Output Suitable for Industrial Systems
Product Overview
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. Key features include a voltage output, single +5 V supply, low power consumption, compact design for PCB mounting, and factory calibration. Its advantages include an extremely low profile (h=12 mm), low footprint, low offset drift, and over-drivable Uref. This transducer is 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.
