1This is a high-efficiency regulated power supply module. When the input voltage is lower than, higher than, equal to the output voltage, the output voltage can be kept stable. 2This module has perfect protection functions and can be applied to solar energy charging. 3The circuit board adopts 1.6 thickened gold plating process. 4The input uses a replaceable fuse to protect the power supply and equipment. 5Adopts patch, low resistance, high frequency electrolytic capacitors, so that the ripple drops to freezing point. 6Constant voltage, constant current, undervoltage protection. 7Using oxidized heat sinks to dissipate heat, the heat dissipation effect is better than that of the aluminum heat sinks. 8The inductor is made of iron-silicon-aluminum for lower heat generation.Item Type:Automatic Step Up Down Voltage Regulator Input Voltage: DC5-32V (Recommended more than 10V) Output Voltage: DC1V-30V continuously adjustable Output Current: 10A (MAX), long-term 7A Output Power: Long-term 80W, peak 130W, please strengthen the heat dissipation when more than 80W Output Ripple: 50mV (Measured at 12V to 12V, 5A) Short Circuit Protection: Yes Input Reverse Polarity Protection: None, if necessary, connect Schottky diodes at the input end Output Anti-Backflow: None, if used for battery charging or inductive load, please connect Schottky diode at the output end Size: 77.6x46.5x15mm / 3.06x1.83x0.59in Adjustment Method:
