Features: *Made of high quality materials, *Built in thermal shutdown function, current limit function, output short protection function. *Fine workmanship and performance. *High efficiency. *Easy to use. *Long life. *As a Battery Charger *Module without constant function can not be used to charge the battery, because the complete consumption of battery charger great pressure, leading the charge current is too large, causing damage to the battery, so when the battery begins to use a constant current charging when the charge to a certain extent, when to automatically switch back to the constant voltage charging. Specifications: Input Voltage Range: 5~32VDC(Note: input voltage not exceeding 32V) Output Voltage Range: 0.8-30VDC adjustable Output Current: 0-5A(adjustable) High Efficiency: up to 95% Input reverse polarity protection: None(if required, high current diode in series with the input).
