The LEM USA Inc. model HO 40-NP-0100 is an innovative open-loop multi-range current transducer, crafted to provide reliable voltage output across various applications. Featuring a compact design optimized for through-hole technology (THT) PCB mounting, this transducer operates efficiently with a single +5 V power supply, ensuring low power consumption. One notable feature of the HO 40-NP-0100 is its galvanic isolation between the primary (input) and secondary (output) circuits, enhancing safety and system integrity. Additionally, its over-current detection mechanism, which triggers at 2.93 times the peak current, integrates EEPROM Control for precise calibration and operation management.
