The VMBSMPS Velbus DIN Rail Switch Mode Power Supply Module is designed for use with the Velbus home automation system. 54W Switching power supply (11..13V). It has the same functionality as our VMBTR1+ VMB3PS combination and provides a suitable voltage for your Velbus installation. However, the voltage is slightly lower which makes it less suitable for very long and thin cabling (UTP).
