Overview
1.2 About the feature
Note
ELMS feature also works without an AC incomer meter.
Note
The PLC can only control the real power consumption P of the charger. The reactive power due
to installed EMC filters cannot be controlled. In standby mode, real power P is low, and the
reactive power Q constitutes the major part of the apparent power S. As soon as the load
increases, the power factor rapidly increases to > 0.9 and beyond.
Note
If ELMS is configured, Router 1 cannot establish a connection to the internet via the wired WAN
since ELMS uses this interface.
