Electrical parameters (non-isolated buck-boost module):
1. Input voltage: DC5-32V, the recommended voltage is above 10V 2. Output voltage: DC1V-30V continuously adjustable 3. Output current: 10A (MAX) within 7A for a long time 4. Output power: long-term 80W, peak value 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 Schottky diodes in series at the input 7. Output backflow prevention: None, if it is used for battery charging or the load is an inductive load with its own, please connect a Schottky diode in series at the output 8. Size: 77.6*46.5*15mm 9. Short circuit protection: Yes 10. Weighs about 45 grams
Debugging method:
1. Battery under-voltage protection adjustment method: (Take 12V lead-acid battery to set 10V under-voltage protection and turn off the output as an example) Adjust the input and stabilized power supply to 10V, adjust the undervoltage protection potentiometer (clockwise increase, counterclockwise decrease), until the fault indicator (red light) just lights up, that is, 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 skip the setting; 2. The output voltage adjustment method: the input is connected to the power supply (the voltage is higher than the undervoltage protection value), the red light is off, the blue light is on, the output is connected to a multimeter, and the output voltage potentiometer is adjusted (clockwise to increase, counterclockwise to decrease), Until the required voltage; Note: Normally, the red light is off and the blue light is on. Otherwise, it is faulty. Input under-voltage protection, output over-current protection, output short-circuit protection, please troubleshoot and re-power on. 3. Output current adjustment method: (Take a 12V input to charge a 12V lead-acid battery with a charging current of 5A as an example) The input is connected to the 12V power supply, the multimeter is in the current range, and the output is connected to the multimeter (the red test lead is connected to the output positive, the black test lead is connected to the negative, and the output is directly shorted. It is recommended to use a current range of 15A or more to prevent burning of insurance), adjust the constant current potentiometer (Clockwise increase, counterclockwise decrease), until the current shows the required value of 5A, remove the multimeter, connect the battery to charge normally. If using an ammeter to adjust the output current, refer to the corresponding wiring of the ammeter for correct wiring and debugging. Note: For constant voltage equipment, only the maximum output current needs to be set.
