Siemens LOGO!POWER Switched Mode DIN Rail Power Supply, 230V ac, 15V dc dc Output, 1.9A Output, 28.5W

This Siemens switch-mode DIN rail power supply delivers secure and reliable power to industrial, domestic and commercial applications. It's a heavy-duty and durable component that operates in temperatures between -25°C and +70°C, so you can confidently use it in harsh environments like hot and humid industrial kitchens. It converts an input of 230V to 15V DC (direct current) to deliver reliable performance. A unique flat and stepped design makes the unit highly flexible and compatible with enclosures like distribution boards. You can use it to power a wide variety of DC-operated devices like sensors, motors and actuators.

• Overload and short-circuit protection ensure the device enters a regulation state or cuts off when voltage differences increase or spike
• High efficiency of up to 90% to minimise power use
• Design allows for simple output current measuring without disconnecting the cable

All AC/DC converters, like this one from Siemens, have built-in fuses, so you won't need additional fuses for external protection.
