Load manager for up to 20 charging points, static/dynamic, with OCPP1.6J for backend. The load manager as a series-mounted device with integrated software for mounting on a DIN rail is the central control device for regulating multiple charging stations and prevents overloading of the mains connection. The device can be used as a direct measurement of currents per phase up to 63 A or as a transformer measurement up to 2500 A. The load manager is operated as static or dynamic load management: - static load management: the maximum available power for the charging stations is set as a fixed value - dynamic load management: the maximum available power for the charging stations is calculated based on the total consumption of the electrical system and the protection of the mains connection and made available to the charging stations. Connection: line connection L1-L2-L3 output and L1-L2-L3-N input, 2 x RJ45 interfaces LAN 1 and LAN 2, B(A) Modbus connection (not yet activated) and B(B) is not used. Function display: LED display for PWR network display, APP application, NET network and BTN reset button. System functions: - Management and use for user approval (authentication via RFID cards), monitoring, non-calibration law compliant or calibration law compliant billing - Configuration of the charging stations directly via the load manager - Creation and management of groups for selected charging stations - enables communication of all charging processes to a backend system. Note: Depending on the charging station type, the charging station data is displayed directly in a Hager Cloud via the load manager or transferred to the backend to third-party providers or via external backend systems via the OCPP application protocol. The selected data is made available on a smartphone, PC/laptop, Hager Cloud or backend provider.
