K6CM

Motor Condition Monitoring Device

K6CM

Quantifying the status of a three-phase induction motor and pump. The alarm output threshold default is set. You can customize the value according to the site. As for comprehensive current diagnosis, the degradation can be detected comprehensively by combining each motor part and the load side. The insulation resistance of the three-phase induction motor and pump can be measured with current flowing (the secondary side leakage current of the inverter can also be detected).
