Enertex® KNX PowerSupply 960³
The Enertex® power supply KNX PowerSupply960³ (6 SU) with integrated choke supplies the KNX bus with a DC voltage of 30 V DC at a current of 960 mA. In addition, the device offers two further unchoked auxiliary voltage outputs (AUX A and AUX B), each with an output current of 320 mA. Both auxiliary voltage outputs have a 100% overload capacity and can be used to supply further devices or, using additional external KNX chokes, to supply further KNX lines. Each of the three outputs has its own current limiter, which protects against short circuit and overload. The limitation is selective, so that if one output or KNX line is short-circuited, the other two outputs can continue to operate normally.
The device also has measuring and diagnostic functions. Measured values and device parameters are shown on the OLED display of the device, e.g. current, voltage and peak current with time stamp for the KNX and both auxiliary voltage outputs. Commissioning, maintenance and analysis of the KNX installation is thus significantly simplified.
Further measurement and diagnostic data is made available via group objects at the bus, including the internal housing temperature, telegram rate, energy meter and the latest bus voltage failure, the latest bus voltage recovery and the latest remote reset with time stamp.
Communication via group addresses is carried out with standard KNX protocol unencrypted or encrypted with KNX Data Secure. With the help of two KNX group addresses, a separate voltage reset can be carried out for both the KNX bus and the auxiliary voltage output AUX A.
In addition, the KNX PowerSupply960³ has an integrated real-time clock with a power reserve of approx. 36 hours and can be parameterised as a KNX clock. A comprehensive time switch application with 64 switching times for max. 64 group addresses, including extensive logic functions, holiday calendar and astro function is integrated. The time switches can directly address KNX group addresses for switching, dimming, blinds, scene, colour RGB, colour HSV and heating controller’s operating mode.
