Picture 1: The Light-Power-Module has to get a direct current
supply of between 12 and 24 Volt. Each of the 24 outputs can
cover a maximum load of 2,5 Ampere.
Picture 2: Switched mode mains power supply are especially
suitable for the supply to the Light-Power-Modules because of the
possibility to supply a higher current level. Switched mode mains
