Siemens SITOP PSU6200 Switched Mode DIN Rail Power Supply, 120 → 230 V ac / 120 → 240V dc ac, dc Input,

Boost the performance of your machinery with this switch-mode DIN rail power supply from Siemens. It converts a wide input range of 85 to 264V AC (alternating current), so you can use it with common applications like control boxes and ITE (information technology equipment). High levels of efficiency ensure a secure and reliable power supply, even during large fluctuations in voltage. This unit delivers a constant current of up to 9V DC (direct current) in the event of overloads to keep equipment running and prevent production downtime.

• Short-circuit protection ensures the device goes into a regulation state when the voltage difference between the inputs and outputs increases to prevent damage to the unit and linked applications
• LED (light-emitting diode) display lets you determine the status of the power supply and respond to faults

Power supplies come in three subsets: linear, switched and battery-based. A switch-mode power supply, like this one from Siemens, dissipates power more efficiently by alternating between on and off states.
