DESCRIPTION
The PLC_IN and PLC_OUT modems are primarily used for transmitting the signal within the
VoltGuard
electric vehicle
charging infrastructure system. They can also be used as the replicators of digital signals in a wide range of applica-
tions. For example, they are used to transmit the tariff signal to the appliances switched on only at the particular tariff
period. This solution can replace the cabling that is difficult to install, for example, in historical houses or new large
buildings.
VOLTGUARD SYSTEM
The
VoltGuard
system is used for optimization of electric vehicle charging in areas with limited charging current values.
A typical example is a detached house with its own consumption that needs to charge an electric vehicle. In this case
you can set a very low available current capacity, so that the usual activities of the residents were not limited and the
electric vehicle charging was not significantly delayed. Or you can install the
VoltGuard
system that always sets the
maximum residual current value on the charging station (residual current = total input breaker capacity – immediate
home consumption) and regulates it dynamically according to household operations. The communication between the
HomeGuard residual capacity meter and the PortGuard charging control unit can be done by means of a twisted pair or
the PLC communication using the ShiftGuard modules.
The communication between the HomeGuard and the PortGuard modules is done by means of RS485 twisted pair.
Before it is connected, you have to set the modem connected to the HomeGuard module as the Master modem and the
modem connected to the PortGuard module as the Slave modem. The modems communicate with sufficient frequency
to ensure reliable dynamic switching of the residual current value in the PortGuard module.
