Description: This is a high efficiency regulated power supply module. Output voltage can keep stable when input voltageis below, above orequal to the output voltage.For example, if the output voltage is set as 12V, then even the input voltage changes from 5V to 32V, the output voltage will still be 12V.This module has well protection function, which can be applied to solar battery charging. Features: 1, The circuit board is thickly plated. 2, The fuse of input can be changed, to protect power supply and equipment. 3, Using chips, low resistance and high frequency capacitor. 4, There is aluminum plate on the back, fixed by thermal conductive silicone, which can guarantee heat dissipation. 5, The material ofinductoris sendust. With 0.8 double wires, it can heat less. 6, Constant voltage, current and low voltage protection(MPPT is better charged by solar power). Output error indicator light will turn on when there is a short circuit or much error of output voltage. Specifications: Input Voltage:DC 5V-32V(suggest 10V above ) Output Voltage:DC 1V-32V(adjustable), default is 12V Output Current:10A(max),less than 7A(suggested),4A(default) Output Power:80W(suggested), 130W(max). Please add more heat sink when power is more than 80W. Output Ripple:50mV (measured at 5A, 12V to 12V) Reverse Input Protection:Not support. If needed, a hot carrierdiode can be added in series atthe input. Output Intrusion Protection:Not support. If need to charge, a hot carrierdiode can be added in series atthe output. Working Temperature: -45 to and85℃; Size:7.8 x 4.6 x 1.5cm / 3 x 1.83 x 0.59"(including bottom aluminum heat sink); Short Circuit Protection: Support Weight: 58g(approx.) Package includes: 1 x Regulator Charging Module Note: 1. Please allow 1-3mm error due to manual measurement. Thanks for your understanding. 2. Monitors are not calibrated same, item color displayed in photos may be showing slightly different from the real object. Please take the real one as standard. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
