ITEM NAME:LTC3780 Power Supply Module 130W Automatic Lifting Pressure Step Up-Down, Input Description: This power supply is a kind of high voltage power supply module, output voltage can keep stable when the input voltage is below, above or equals to the output voltage. the output voltage can be maintained constant. This module has a perfect protection function, and can be widely used in notebook power, vehicle power supply, solar charge etc. Advantages: The circut board is proccessed with 1.6 thick gold-plated. The input uses replaceable fuse which protects the power supply and equipment. The whole electrolysis uses imported patch, low resistance, high frequency capacitor that make the ripple down to the freezing point. IC is original improted Linear IC. Constant voltage, constant current, under voltage protection (MPPT is more suitable for solar charging) Output error indicating light will light when output voltage seriously and short circuit is fault. Back plate ensures good heat dissipationthe with heat conducting silicon film i fixed on the bottom of your module. Inductor used iron silicon aluminum, 0.8 double winding, generate less heat. Input voltage : DC5-32V; Output voltage : DC1V-30V adjustable continuously; the default.1 Piece LTC3780 power module.
