Feature: 1. This power supply is a high-efficiency stabilized power supply module. When the input voltage is lower than, higher than, or equal to the output voltage, the output voltage can be kept stable. 2. With perfect protection function, it can be applied to solar charging 3. The circuit board adopts 1.6 thickened gold plating process, and the input uses a replaceable fuse to protect the power supply and equipment 4. The whole version of the electrolysis adopts imported original patches, low resistance and high frequency capacitors, which reduces the ripple to the freezing point 5. IC adopts imported original, with constant voltage, constant current, undervoltage protection (MPPT is more suitable for solar charging) 6. With output error indicator, it lights up when the output voltage drift is too serious, short circuit and other faults 7. Oxidation heat sink heat dissipation, the heat dissipation effect is better than that of natural aluminum 8. The inductor uses iron silicon aluminum with less heating Specification: Item Type: Power Supply Module Electrical Parameters: 3. Output Current: 10A (maximum) within 7A for a long time 4. Output Power: Long-term 80W, peak 130W, more than 80W, please strengthen heat dissipation 5. Output Ripple: 50mV (12V to 12V, measured at 5A) 6. Input Reverse Connection Protection: None, if necessary, please connect a Schottky diode in series with the input 7. Output Anti-Backflow: None, if used for battery charging or the load is a self-charged emotional load, please connect a Schottky diode in series with the output 8. Size: Approx. 77.6 x 46.5 x 15mm / 3.1 x 1.8 x 0.6in 9. Short Circuit Protection: Yes 10. Weighs: Approx. 45g / 1.6oz Debugging Method: 1. Adjustment Method of Battery Undervoltage Protection: (take 12V lead-acid battery to set 10V undervoltage protection, turn off the output as an example) Adjust the input connected regulated power supply to 10V, adjust the undervoltage protection potentiometer (increasing CW, decreasing CCW) until the fault indicator (red light) lights up, and the setting is successful; so when the battery is discharged to 10V, It will automatically cut off the power supply to protect the battery from damage. Note: If it is not battery-powered, you can not set it; Note: Normally, the red light is off, the blue light is on, otherwise it is faulty. Input undervoltage protection, output overcurrent protection, output short circuit protection, please remove the fault and power on again. 3. Output Current Adjustment Method: (take 12V input to charge 12V lead-acid battery, charging current 5A as an example) The input is connected to a 12V power supply, and the output is connected to an ammeter (the red test lead is connected to the positive output, the black test lead is connected to the negative, and the output is directly shorted. It is recommended to use an ammeter above 15A to prevent burning), adjust the constant current potentiometer (CW increase, CCW decreases) until the ammeter shows the required value of 5A. Remove the ammeter and connect the battery to charge normally.. Package List: 1 x Power Supply Module
