Recom Switching Power Supply, RAC04-05SK/277, 5V dc, 800mA, 4W, 1 Output, 80 → 305V ac Input Voltage

Transform electrical power from AC to DC voltage using this switching power supply from RECOM. When combined with a switching regulator, it converts power from a high-input to low-output voltage for safe and versatile use in low-powered machinery. A single output design helps reduce your wiring needs for easy installation in compact applications. To boost safety, the unit has a non-conductive encapsulated package that insulates users from shocks. An input voltage tolerance range of 80 to 305V AC means you can use it with multiple power sources, so it's a flexible choice. This device is lightweight at 30g, so it won't put strain on your PCB.

• Mechanical operational life of 105,000 hours at 277V AC for long-term performance
• Output voltage of 5V DC to suit low-voltage applications
• Wide operating temperature range between -40°C and +90°C for use in tough conditions

• Railway signalling devices
• Factory automation systems

Yes, this component has compact dimension of 36.7 (L) x 27.2 (W) x 17.4mm (H), so it uses minimal space in your setup.
