Power classes ranging from 10 W to 24 W at an 230 V_AC input with four potentially isolated outputs. This all-round concept for power classes up to 50 W is characterised by high peak loads, power sharing between all outputs and high current carrying capacities in combination with robust mechanics and an electronically variable design.

Various mechanical designs are possible since there is no extensive need for cooling and a lot of SMD technology can be used for the power components. The power supply unit in top-hat rail design is used for the supply of electronics in freezers of supermarket chains. These devices have been operating reliably since the old millennium. The units are being adjusted to the latest standards regularly. Field failure rate < 0.01%
