.A KNX power supply ensures smooth operation in modern intelligent buildings where KNX systems are installed. Systems may be simple, with just a few devices, or complex systems with hundreds of devices throughout a building.

Intelligent Building Control

The demand for versatility and comfort has driven the need for intelligent building control. KNX systems were developed to reduce design and installation times by removing the need for complicated wiring. As a result also reducing the high risk of fire present due to the previous density of cables. This new installation creates uni-communication between any controller, sensor and actuator, using a two wire bus routed transmission of signals between devices which are installed in parallel to the mains wiring.

Intelligent building control applications can include heating/ventilation and air conditioning control, shutter/blind control, alarm monitoring, energy management, security system control, automation and remote access control.

KNX Power Supply

Whether you are looking to create a simple residential set-up or a complex intelligent building a KNX bus requires a KNX power supply to ensure the correct signals are transmitted to installed devices.

KNX-20E-640 is engineered to be a reliable and safe solution for KNX bus environments. This 19.2W 640mA 30V EIB/KNX power supply has wide -30 to +70C operating temperature range, high efficiency and a small footprint of only 3SU (52.5mm). Ideal for installation on DIN rail TS-35/7.5 or 15. With an integrated KNX bus choke output and an additional output for ancillary power.
The small and compact design includes LED indicators to show normal operation, overload conditions and reset operations; the KNX power supply also has protection modes for short circuit, overload and over voltage and cooling is by free air convection.
