Input voltage range: AC45v-27NVDC65V-390V under light loadAC7oV27Dc10Ov-390V under heavy loadNo load power:Less than 0.05W Full load power:Less than 4WOutput characteristics: multiple modules with the same voltage can be connected to the requirements of small space and current.Output voltage: about 5V+0.15V no-load and full load, 0.1V reduced under light load, recovered under heavy load, 60mV ripple under 50% loadOutput current: 5vomA-700mA, entering constant current working mode when fully loadedTest resistance: 7 ohm for 5V (7R * 700MA=4.9V)Output indicator: red lightOutput power: 3.5W, efficiency about 70-80%Output protection: overvoltage, overcurrent, over temperature, over power, short circuit protection, etcDue to different batches, the appearance and color of the product , it does not affect the useColour:As ShownMaterial:PCBtype:5VPackage Contents:5 x Switching Power ModuleOnly the above package content, other are not included.Note: Light reflection and different displays may cause the color of the item in the a little different from the real thing. The measurement allowed error is +/- 1-3cm.
