EKEPC2-C/S EPC EV Charge Controller

Use EKEPC2-C/S when you need a compact EVSE control board for commercial or residential AC chargers with contactor control, status management, Modbus-RTU communication, RFID start, residual current monitoring options and dynamic load balancing.

What the controller does

Controls the AC contactor that switches charging power on/off
Manages Mode 3 / Level 2 charging logic for AC EVSE designs
Supports communication and monitoring over RS485 / Modbus-RTU
Extends commercial features such as RFID/IC card start, RCM residual current monitoring and DLB dynamic load balancing
Fits DIN-rail EV charger assemblies for OEM and system integrators

Key capabilities

Standards fit: IEC 61851-1 and SAE J1772 oriented Mode 3 / Level 2 control
Current class: output control suitable for designs up to 63A
Smart charging: Modbus-RTU over RS485 for remote status, protection parameters and integration
Access control: RFID / IC card authentication for shared or commercial piles
Safety options: residual current monitoring (RCM) path for leakage detection in EV charging circuits
Site power management: DLB support to help avoid overload in multi-charger installations
Operator UX: LCD / energy metering oriented designs for status and kWh visibility
Session security: electronic lock and emergency-stop oriented interfaces for public/commercial use

Typical applications

AC wallbox and pedestal EV charger OEMs
Commercial parking and fleet AC charging cabinets
Home / workplace Mode 3 chargers needing smarter control than a basic board
Projects that need RS485 Modbus integration to meters, gateways or site EMS

EKEPC2-C vs EKEPC2-S

Both belong to the same EKEPC2 controller family for AC charging piles. Select EKEPC2-C or EKEPC2-S according to the interface/configuration required by your charger design. For RS485 commissioning (A/B wiring, baud rate, Modbus address and register map), see the setup guide: EKEPC2-C/S RS485 communication setup.

EKEPC2 vs EKEPC3 (quick guide)

• EKEPC2-C/S: Mode 3 / Level 2 EPC controller focused on contactor control, Modbus-RTU/RS485 and common commercial EVSE features (RFID, RCM, DLB).
• EKEPC3: choose when the project needs the OCPP-oriented EKEPC3 controller path instead of the EKEPC2 Modbus-centric stack.
