Product Description

WM 400 SERIESAC Current Measurement

DESCRIPTION （TRUE RMS responding）

WM 400 True-RMS ac current transducers series are designed for applications where AC current waveforms are not purely sinusoidal. They are more precise and accurate than other transducers and are ideal in chopped wave and phase fired control systems.

APPLICATIONS

TURE-RMS sensing products are good applications of VFD (variable frequency drive) Controlled Loads, SCR (silicon-controlled rectifier) controlled Loads, and Switching Power supplies and Electronic Ballasts. SELECT WM400 TRUE RMS series transducers for non linear loads in “NOISY POWER” environments

Building Automation,

Energy Management

Monitor motor faults

Monitor lighting elements

Monitor heating elements

WM 400 series AC current transducers have meet requirement of IEC 61010-1
