What’s the difference between the UPM100 and UPM101?

The UPM100 is a compact power monitor that measures the following in industrial devices and other factory instruments: apparent, active, reactive, integral active, integral reactive, integral regenerated, and integral apparent power, instantaneous values of effective voltage and current at each phase, and the instantaneous power factor.

The UPM101 is a compact power monitor that enables the same measurements as the UPM100 by clamping a dedicated CT on the secondary line of the factory’s existing CT.
