The power supply is a kind of high-efficiency voltage automatically regulator.Whatever is the input voltage value,the output voltage can be maintained constant.For example,set the output to 12V, then the variation of the input voltage in the range of 5-32V,the output voltage in the 12V invariant.This module has a perfect protection function, and can be widely used in notebook power,vehicle power supply, solar charge etc.The input uses replaceable fuse to protect power supply and equipment.The whole electrolysis use patch, low resistance, high frequency capacitor,to make the ripple down to the freezing pointConstant voltage, constant current, under voltage protection (MPPT is more suitable for solar charging)The output has error indicating lamp,it will light when the output voltage drift too serious,short circuit and other faultInductor use iron silicon aluminum, 0.8 double winding, generate less heat.Input voltage: DC5-32VOutput voltage: DC1V-30V continuously adjustable; the default 12VOutput current: 10A (MAX) ,long term within 8AOutput power: 80W, 130W, more than 80W please strengthen heat dissipationOutput ripple: 50mV (12V turn to 12V, 5A measured)Short circuit protection:YESInput reverse connection protection: NoOutput prevent reverse connection protection: NoOperating temperature range: -45 ~ +85 Degrees CelsiusSize: 77.6x46.5x15mm/3.06x1.83x0.59 inch (including the bottom surface of the radiating aluminum)Colour: Picture ColorMaterial: PlasticPackage Contents:1 * LTC3780 ModuleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
