OH/GEN
DIN-rail energy management module for CAME Domotic 3.0: load shedding for up to 8 loads, power metering via toroids and one 10 A relay output.
The OH/GEN is the energy management module of the CAME Domotic 3.0 system. It keeps total household consumption below the contracted power limit by switching off lower-priority loads when the supply is close to overload, so the main breaker does not trip.
Power is measured through current toroids: one OH/TR01 toroid is included, and up to three can be connected to monitor separate circuits. This also makes it possible to compare the energy produced by a photovoltaic system with the energy drawn from the grid and to switch loads according to the actual production.
Used on its own, the module manages up to eight loads. Combined with the ETI/DOMO server, consumption is passed to the server, which handles load management and shows live and historical data on the touch screens and in the app.
Key features
- Load management for up to 8 loads based on priority
