This power supply unit (PSU) from Siemens is designed to provide electrical energy to DIN-rail-connected devices. The component works by converting alternating current (AC) voltage to the direct current (DC) voltage required for industrial equipment. It effectively manages power delivery across the entire load range and ensures low power loss in no-load operations for high levels of efficiency. Thanks to a built-in electrical fuse, the unit is protected from overcurrent and short circuits. It also supports parallel switching for enhanced performance. Thanks to compact dimensions of 90 (height) x 72 (width) x 53mm (depth), this is a reliable solution for applications where space is limited.

• Mean time between failures (MTBF) of 2,391,480 hours for reliable, long-term performance
• Simple snap-on mounting on DIN rails saves time and effort
• Double-layer insulation eliminates the need for an earth connection and improves electrical safety
• Screw termination type for easy installation without the need for specialist tools

A DIN rail is a metal support structure inside an electrical enclosure that's used to mount circuit breakers, power supply units and programmable logic controllers (PLCs). Its main function is to make installation easy and improve space management.
