RS PRO Switching Power Supply, 12V dc, 250mA, 3W, 1 Output, 110 → 370 V dc, 85 → 264 V ac Input Voltage

Use this RS PRO switch-mode power supply (SMPS) to convert both AC and DC input voltages for charging DC-current compatible appliances. The embedded unit has a high power density and boasts very little energy loss, so it's efficient with electricity.
The small unit's benefits include protection from short-circuits and overheating, so it's both safe and reliable. It's housed in a DIP 26 (dual in-line packaging) plastic case that contains no adhesives, contributing to a light environmental impact.
This SMPS complies with EMC EN55022, level A, so it doesn't pose any safety risks from electromagnetic radiation, even with daily use. You'll find this piece also meets UL (Underwriter Laboratories) approval and European standards for functional safety in electrical equipment.
