Check the listing for details. 50PC DCDC LTC3780 automatic elevating voltage solar power module ultra compact. Condition: New. Listed at 29.66 USD. DCDC LTC3780 automatic elevating voltage solar power module ultra compact Electrical parameters: 1. Input voltage: DC5-32V, it is recommended to use voltage above 10V 2. Output voltage: DC1V-30V continuously adjustable; 3. Output current: 10A (MAX) long-term 7A; 4. Output power: long-term 80W, peak 130W, more than 80W please strengthen heat dissipation; 5. Output ripple: 50mV (12V to 12V, 5A measurement); 6. Input reverse protection: none, if necessary, please connect the Schottky diode in series at the input end; 7. Output anti-backdown: none, if used for battery charging or the load is its own emotional load, please connect the Schottky diode in series at the output end; 8. Size: 77.6*46.5*15mm 9. Short circuit protection: Yes; 10. Weight approx. 45 grams; Debugging method: 1. Battery undervoltage protection adjustment method: (Using a 12V lead-acid battery to set 10V undervoltage protection and turn off the output as an example) The input voltage regulator power supply is adjusted to 10V, and the undervoltage protection potentiometer is adjusted (increasing clockwise and decreasing counterclockwise) until the fault indicator (red light) is on, that is, the setting is successful; When the battery is discharged to 10V, the power supply will be automatically cut off to protect the battery from damage. Note: If it is not battery powered, do not set it; 2. Output voltage adjustment method: input power supply (voltage is higher than the undervoltage protection value), the red light is not on, the blue light is on, the output is connected to a multimeter, adjust the output voltage potentiometer (clockwise increase, counterclockwise decrease), until the required voltage; Note: Normally, the red light is off, and the blue light is on. Otherwise, the input undervoltage protection, output overcurrent protection, and output short-circuit protection are faulty. Please rectify the fault and power on again. 3. Output current adjustment method: (12V input charging 12V lead-acid battery, charging current 5A as an example) The input is connected to 12V power supply, and the output is connected to the ammeter (red pen is connected to the output positive, black pen is connected to the negative, and the output is directly short-circuited. It is recommended to use an ammeter above 15A to prevent burning insurance), adjust the constant current potentiometer (clockwise increase, counterclockwise decrease), until the ammeter shows the required value 5A, remove the ammeter, and connect the battery to charge normally. Note: If used for constant voltage equipment, only need to set a large output current.
