In existing buildings there is wiring where access to the 230V connection of the consumer is not easily possible, e.g. lighting fixtures permanently installed in the wall. The digitalSTROM dSready 'IC REG Switch-Dimm' X-IC-40-0001 module is designed for installation in the sub-distribution and for connecting electrical consumers such as ceiling and wall lights. This means that connected lights can be switched on and off via the 230V power line using digitalSTROM commands and their brightness can be changed in dimmer mode. Integrated latest GE-TKM300 digitalSTROM technology for improved dimming function and lower standby consumption.
