AC MAX Smart
The Delta AC MAX Smart combines efficient single- or three-phase charging up to 22 kW with integrated Ethernet, Wi-Fi and a built-in cellular modem. Connect it to your network or a charging back-end via OCPP 1.6 for remote management, user authorization and billing — and integrate it with building energy management via Modbus TCP. RFID authentication provides secure, personalized access.
No LAN on site? No problem — every AC MAX Smart includes an internal 2G/3G/4G modem. Plug-and-play installation, over-the-air firmware updates and a robust IP55 enclosure make it a future-proof choice for advanced residential and commercial charging.
