The supply is a kind of high-efficiency voltage automatically regulator.Whatever is the input voltage value,the output voltage can be maintained .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 , vehicle supply, solar charge etc.The input uses replaceable fuse to protect supply and equipment;The whole electrolysis use patch, low resistance, high frequency capacitor, to make the ripple down to the freezing point; voltage, 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 fault;Inductor use iron silicon aluminum, 0.8 double winding, generate less heat.Parameters:Input voltage: DC5-32V; it is recommended to use a voltage above 10V.Output voltage: DC1V-30V continuously adjustable;Output current: 10A (MAX) ,long term within 8AOutput : 80W, 130W, more than 80W please strengthen heat dissipationOutput ripple: 50mV (12V turn to 12V, 5A measured)Short circuit protection:YESInput reverse connection protection: No ( if necessary, connect a Schottky diode in series with the input);Output prevent reverse connection protection: No (If it is used for battery charging or the load is a self-contained electric load, please connect a Schottky diode in series at the output end);Operating temperature range: -45 ~ +85 centigradeColour:blueMaterial:Circuit board + electronic accessoriesSize:77.6 x 46.5 x 15mmPackage Contents:2 x supply 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.
