Features High Quality Assurance: The circuit board adopts 1.6 thick gold plating process, and the whole plate electrolysis adopts imported original patch, low resistance and high frequency capacitors, which reduces the ripple to freezing point. Not Easy to Heat Up: The charging module is made of iron, silicon and aluminum, which generates less heat. The oxidation heat sink dissipates heat, and the heat dissipation effect is better than that of the natural aluminum sheet. Safe Use: There are constant current, constant voltage, undervoltage protection, as well as output indication and fault indication functions, and the output has overcurrent, overvoltage and short circuit protection; all components can reach industrial grade applications. Multi-scene Usage: Buck boost voltage converter can be perfectly used in various occasions, such as charging, high-power LED drive, equipment power supply, vehicle power supply, etc. Replaceable Fuses: Inputs feature replaceable fuses to protect power and equipment. Specification: 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: 1. Battery undervoltage protection adjustment method: Connect the input to regulated power supply and adjust to 10V, adjust the undervoltage protection potentiometer, until the fault indicator is on, the setting is OK; Then when the battery is discharged to 10V, The power supply is automatically cut off to protect the battery from damage. 2. Output voltage adjustment method: Connect the input to power supply, red light is off, blue light is on, connect output to a multimeter, adjust output voltage potentiometer to the required output voltage. 3. Output current adjustment method: Connect the input to 12V power supply, parallel the output to the multimeter, adjust constant current potentiometer, until the current shows the required value of 5A, remove the multimeter, and connect the battery to charge normally.
