Features: This is an electronic power supply module that incorporates a switching regulator to convert electrical power efficiently. Like many other power supplies, it transfers power from AC85V~264V or DC110 ~370V source to DC5V, 2A. Switching regulators are used as replacements for linear regulators when higher efficiency, smaller size or lighter weight are required. It supports over temperature protection, over current protection and short circuit protection. High conversion efficiency and low output ripple noise, isolated power supply module has high output accuracy. Specifications: Type: Isolated power supply module Input Voltage: AC 85V to 264V(47Hz~63Hz), DC 110V to 370V Input Current: 0.5mA(115VAC), 0.25mA(230VAC) Output: DC 5V/2 A I nput Surge Current: 10A(230VAC) Rated Output Power: 10W Efficiency: 75% Over Current Protection: Yes Over Temperature Protection: Yes Short Circuit Protection: Yes Size: 66 x 30 x 22mm / 2.59 x 1.18 x 0.86" Mounting Hole Diameter: 3.2mm / 0.12" Package Includes: 1 x Power Supply Module
