Product overview and key benefits. This intelligent AC charger controller is a compact control unit for charging electric vehicles that controls and monitors the entire AC charging process. It provides secure user authorization, dynamic load management to prevent overload of existing AC supply, and reliable relay control for the charging contactor. Why customers need this controller and how it solves problems. - The controller enables secure, authorized charging and reduces unauthorized use by supporting backend communication for user authentication. - The unit prevents electrical supply overload by performing dynamic load management and distributing charging load effectively. - The controller simplifies integration with existing electrical protection by driving an external AC contactor through its relay output. - The unit provides clear status feedback with tri-color LED indicators for fast diagnostics and straightforward operation. Core functions and standout features. - The controller regulates and supervises AC vehicle charging and supports common EV connector types Type 1 and Type 2 for broad vehicle compatibility. - Selectable maximum charging current is available via an internal selector switch with options of 10 A, 16 A, 20 A, 25 A, and 32 A, with factory default set to 32 A. - Two enclosure variants are available, identified by version codes: c for the version with a permanently attached charging cable, and s for the socket-only version without an attached cable. - The c version has the charging cable fixed to the controller and connects the pl and p2 terminals to the AC contactor that supplies the charging current. - Relay output is provided to control an external AC contactor for safe switching of the charging load. - The controller supports software configuration options identified as ekepc1 and ekepc2 for flexible system setup. - Tri-color LEDs indicate operational states and fault conditions, making status checks quick and intuitive. - The unit performs an internal self-test on power-up, including verification of the DC leakage detection module when installed. Optional modules and interfaces. - Contactless IC card reader module can be fitted for local user authorization. - DC leakage detection module, named RCmu, is supported for detection of DC faults when required. - RS485 communication interface is available for integration with local controllers or backend systems. - Plug-lock device and external emergency stop input are supported for enhanced physical security and safety control. Installation and compatibility notes. - The controller is suitable for single charging point installations for private and industrial applications. - Mounting is designed for standard guide-rail installation for easy electrical cabinet integration. - The nominal value of the external miniature circuit breaker must be selected within the configured maximum current range to ensure correct protection. - Connect the protective earth conductor first during installation and connect CP directly to the vehicle charge pilot terminal for correct signaling and safety. Typical operational sequence. - On application of mains power the controller runs automatic initialization and self-diagnostics
