There are two (2) modes which can be set for energy harvesting operation, with bits EH_MODE: • Energy harvesting optimized for low field strength (default) - if expected VCDs have lower NFC field strength (e.g. NFC mobiles). The low field strength mode is optimized for high energy harvesting efficiency and can drive up to 20 mW output power.

Energy harvesting and NFC

The following features make NFC particularly interesting for installers and OEMs: The modules do not need to be removed from their switch frames for commissioning and configuration. Storage costs are reduced because the devices can be configured directly on-site. With NFC, the complete commissioning of the device can be documented.
