WM 400 SERIES AC Current Measurement
DESCRIPTION (AVERAGE RMS responding)
WM400 Series current /voltage transducers combine a current transformer and signal conditioner into a single package. This provides high accuracy, low wiring costs, easier installation and low power consumption and low cost.
APPLICATIONS (For General Applications)
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
