Dynamic Load Management (DLM) for Stand Alone
GTB Twinbox
DLM reduces charging current when demand of current elsewhere
increases. Simple to say, the GTB Twinbox balance the charging
current that you will get as much power as possible to the EV that
is available in the system without any risk to overload the mains
fuses.
To activate DLM, a Modbus energy meter must be installed in
the supply distribution box. The following energy meters are
approved:
• Garo GNM1D-RS485
• Garo GNM3D-RS485 (current transformer 3-phase.
Max current is based on current transformer)
• Garo GM3T-RS485
• Garo GNM3T-RS485
• CG EM 112
• CG EM 270
• CG EM 271
For use in systems that have local electricity production (solar cell,
wind etc)
Garo GNM3D-LP-RS485 (current transformer 3-phase. Max
