MPU-1 leakage current alarm device WMPLMPU1

MPU-1 is designed to monitor (measure) leakage current in power grids, alternating current, low and medium voltage, it is used to perform measurements whose results determine the safety of the monitored installation in terms of flowing current lapse. The device allows you to set a safe threshold value of the flowing leakage current, above which a visual and audible alarm is activated.

The most important features of the MPU-1 device include:

< li> constant monitoring of alternating current flowing through the earthing,
• measurement with one or two clamps at the same time, in the case of measurement using two clamps, the current value is added
• , which makes it possible to cover twin poles (eddy current), independent clamps for each component pole,
• LED indicator of operating mode,
• alarm in case of current flow higher than the alarm threshold (factory set to 1 A), audible and visual alarm (speaker built inside the housing),
• measurement with flexible clamps of the F series by Sonel (Rogowski coil),
• measurements in low and medium voltage networks with a frequency of 50 Hz or 60 Hz,
• automatic measurement range selection,
• battery charge status monitoring,
• ergonomic operation.
