DC 5V-32V to 1V-30V 10A Automatic Step Up Down Voltage Regulator Charging Module LTC3780

1、This 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.

2、This module has perfect protection functions and can be applied to solar energy charging.

3、The circuit board adopts 1.6 thickened gold plating process.

4、 The input uses a replaceable fuse to protect the power supply and equipment.

5、Adopts patch, low resistance, high frequency electrolytic capacitors, so that the ripple drops to freezing point. 6、Constant voltage, constant current, undervoltage protection. 7、Using oxidized heat sinks to dissipate heat, the heat dissipation effect is better than that of the aluminum heat sinks. 8、The inductor is made of iron-silicon-aluminum for lower heat generation.

Item Type: Automatic Step Up Down Voltage RegulatorInput Voltage: DC5-32V (Recommended more than 10V)Output Voltage: DC1V-30V continuously adjustableOutput Current: 10A (MAX), long-term ≤7AOutput Power: Long-term 80W, peak 130W, please strengthen the heat dissipation when more than 80WOutput Ripple: 50mV (Measured at 12V to 12V, 5A)Short Circuit Protection: YesInput Reverse Polarity Protection: None, if necessary, connect Schottky diodes at the input endOutput Anti-Backflow: None, if used for battery charging or inductive load, please connect Schottky diode at the output endSize: 77.6x46.5x15mm / 3.06x1.83x0.59in Adjustment Method:1. Battery undervoltage protection adjustment method: (Set the 10V undervoltage protection and shutdown output with 12V lead-acid battery as an example)Connect the input to regulated power supply and adjust to 10V, adjust the undervoltage protection potentiometer (clockwise increase, counterclockwise decrease), until the fault indicator (red light) 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.Note: If it is not battery powered,do not need to set.2. Output voltage adjustment method: Connect the input to power supply (voltage is higher than undervoltage protection value), red light is off, blue light is on, connect output to a multimeter, adjust output voltage potentiometer to the required output voltage (CW increase, CCW decrease).Note: Under normal condition, the red light is not on, the blue light is on, otherwise there is a faulty, please remove faulty them re-power.3. Output current adjustment method: (Charge for 12V lead-acid battery with 12V input, charging current 5A as an example)Connect the input to 12V power supply, parallel the output to the multimeter, adjust constant current potentiometer (CW increase, CCW decrease), until the current shows the required value of 5A, remove the multimeter, and connect the battery to charge normally.
