DIN EN 50065-1:2012-01

This standard deals with electrical equipment using frequencies in the range of 3 kHz to 148,5 kHz to transmit information on low voltage electrical installations, either on the public supply system or within buildings. It specifies the frequency bands allocated to the different applications, limits for the output voltage in the operating band and limits for conducted and radiated disturbance. It also gives the methods of measurement. It does not specify the modulation methods, the coding methods or functional features (except those for the prevention of mutual interference). The object of the standard is to limit mutual influence between transmission equipment in electrical installations and between such equipment and other equipment. In addition this standard is intended to limit interference caused by signal transmission equipment to sensitive electronic equipment. However, complete freedom from such interference cannot be assured. The responsible committee is Subcommittee UK 716.1 "Systeme für die Kommunikation auf elektrischen Niederspannungsnetzen" ("Communicating systems used in low-voltage installations") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
