Product Overview

CVM-C4 is suitable for electrical panels where installation space is limited but essential measurement, local display and remote communication are required. With a depth of only 41.5 mm, it is useful for compact switchboards, retrofit panels, distribution boards, MCC panels and machine control panels.

The analyzer measures instantaneous electrical values, active and reactive energy, voltage and current THD%, and supports four-quadrant measurement. It can be used for consumed or generated energy logging and for monitoring energy from two different sources using digital input activation.
