PCB mounted current sensor (LEM)
The HXD type LEM sensor is designed for use in the following applications: measured (primary side) current and measurement signals (Fu Bian) are transmitted via a printed circuit board (PCB). This sensor is equipped with 2 primary bus conductor, welding for primary current transmission in PCB. The margin includes the HXD power supply (+ 12- + 15V, less than 30mA), grounding, and 2 independent signal outputs.
The HXD series offers 6 standard models with the same appearance, rated currents of 2x3, 5, 10, 15, 20, or 25ARMS. Analog signals with an output signal of + 4V at rated current. HXD uses an open loop Holzer effect to measure DC, AC, or pulse currents, with high electrical isolation between the primary side and the rest side, and the AC isolation voltage is 4.3kVRMS/50Hz/1min. Their anti-interference ability is strong, and the measuring accuracy relative to the rated current at normal temperature is 1.5% (not including zero).
