The STEP3 bus power supply delivers 1280 mA (max. 1900 mA) at very small form factor of 4 M. The integrated color display enables simple commissioning and shows the relevant KNX status information during operation.
In addition, an active KNX choke ensures very low power loss. Thanks to the wide input voltage range of 85 V AC to 264 V AC and 90 V DC to 275 V DC, the KNX bus power supply can be used worldwide. The device also has an output for a KNX auxiliary voltage.
