KNACRO LTC3780 Automatic Pressure Lifting Power/Constant Voltage Constant Current DC5-32V/10A/Maxium 130W Voltage stabilized/car/solar charging It is a high efficiency voltage regulator power supply module, the input voltage is lower than, higher than the output voltage, the output voltage can remain stable.This module has perfect protection function, can be applied to solar charge. Circuit board with 1.6 thick gold plating process,Input can be replaced by the replacement of the insurance tube, the protection of power and equipment. The whole electrolysis adopts imported SMD, low resistance, high frequency capacitance, the ripple down to the freezing point.IC imported from Linear. Constant voltage, constant current, under voltage protection (MPPT is more suitable for solar charge). Black oxide heat sink cooling, cooling effect is better than the effect of the natural aluminum film.On the back of the aluminum plate, through the thermal conductive silicon film is fixed in the bottom of the module, can ensure good heat dissipation, do not need to consider insulation and heat problem;Iron silicon aluminum, 0.8 wire and winding, heat less.
