3.1 OVERVIEW OF  THE EPC 2.0 

 

 

 

The EPC 2.0 is a DIN rail mounted control module for IEC 61851  compatible EV charge points.  Key features include RCM support and 
PEN Loss detection, helping charge point manufacturers and installers meet regulations in a cost

-

effective way  and protect  against  

electric shock  in the unlikely event  of  an earth and neutral fault problem.
