The Siemens wall-mounted, single-phase Sitop PSU100D switched-mode power supply eliminates the need for traditional rail mounting while meeting basic power supply requirements. It has a low-profile, aluminum casing with an IP20 degree of protection and a temperature range from -10°C to 70°C. Six fan-free variants provide a regulated supply of 24V with rated output currents from 2.1 to 6.25A and 12V with 3 or 8.33A. For higher outputs, 2 devices of the same type can be connected in parallel. The output voltage can be set between 22 and 28V using potentiometers in the 24V variants, and between 11 and 14V in the 12V variant.
