HY50-P / SP22 Current Transducer (LEM)
The HY50-P / SP22 is a compact Hall-effect current transducer by LEM, designed for precise measurement of DC, AC, and pulsed currents in demanding industrial environments. With a nominal primary range of 50 A RMS (extendable to ±150 A), this module provides galvanic isolation between the high-power primary side and sensitive electronic circuits—ensuring both safety and signal integrity.
Featuring a PCB-mount package with low power consumption, the transducer outputs an analog signal of up to ±4 V (with a dual ±15 V supply). Accuracy remains within ±1 %, with a frequency bandwidth up to 50 kHz and a quick response time under 3 µs.
Built with a UL 94-V0-rated insulating case, the HY50-P / SP22 is compact, interference resistant, and durable—suited for use in inverters, SMPS, motor speed controls, UPS units, battery-powered systems, and welding power supplies.Lempowertronics.com.tw
