Smart EV Charge Controller
The EPC 3.0 is our most advanced EVSE controller and your gateway to effortless smart EV charging.
It features all the electrical protection mechanisms of EPC 2.0 whilst adding OCPP 1.6j in an industry leading compact form.
EPC 3.0 functionality includes load management, user access control and back-office integrations for remote scheduling and energy monitoring.
The load management capabilities, which can be configured both locally and remotely, protect against overcurrent and optimise the power distribution in a multicharge point system.
The EPC 3.0 EVSE controller is the ideal technology solution for creating a smart EV charge point, whether for domestic or commercial applications.

Direct OCPP Communication
The built in Wi-Fi and OCPP stack allows the Smart EPC 3.0 to communicate with an increasing number of back-office/Smart charge systems easily and gives immediate access to all the features these powerful platforms offer including payments, load management, RS485 communication, charge scheduling, solar charging and access control. Multiple back-
offices systems are already integrated which will simplify establishing a charge point network and keep development costs low.

LK+
Configuration is dependent:
• Provides a drive current to continuously energise the solenoid interlock
• Provides a drive current to change the motorised interlock state to
locked ( The signal is activated for 500ms and changes to pulsed
500ms intervals until the lock is engaged. ( See LK FB )
Rating 12V 300mA
LK-
Configuration is dependent:
• Provides a return path for the solenoid interlock drive current LK+.
• Provides a drive current to change the motorised interlock state to
unlocked ( The signal is activated for 500ms and changes to pulsed
500ms intervals until the lock is disengaged. ( See LK FB )
Rating 12V 300mA
