6.2.1. Dynamic Load Management (DLM)
You can implement dynamic load management with for this purpose compatible energy meter. The figure
below shows an example how you can build up the system.
•
The energy meter measures the total power consumption and the actual current per phase. If some
other load over the set maximum current for load management is added when charging is ongoing,
the charger will decrease the charging current. If the total power consumption reaches the allowed
maximum power, the charging interrupts untill the the total power consumption has decreased to a
value at which the charging can continue.
•
Use only current transformers which have the same serial number, they are calibrated with one an-
other.
•
1-phase measurement: select the correct parameters in the energy meter’s settings.
•
Please see the energy meter instructions for more detailed information.
