FIN7M. - Mid certified single-phase bi-directional energy meter 5(40) a with s0 pulse output

Coming soon

The Finder 7M. is a MID certified Single-phase Bi-directional energy meter with backlit LCD display, multi-function button, S0 pulse output and IR communication port.

This energy meter is the ideal product for monitoring production of domestic photovoltaic systems and monitoring energy consumption. By combining it with a Velbus VMB7IN 7-channel input module, the active production or consumption is reported over the Velbus network, allowing your home automation system to make smart decisions based on your active energy situation. For example: automatically turning on the air conditioning unit when solar production is above a certain kWh level and using your local energy without sending it onto the global net.

The NFC technology of the Finder 7M. allows reading the measured energy locally, even in the absence of mains voltage and to program and customize the counters via your smartphone.

The 7M. is also distinguished by the touch-sensitive navigation and programming key and by the power/control terminals with integral sealable tamperproof terminal shield.
