Low-voltage AC-DC Step-down Power Module DC-DC Adjustable Regulated Power Supply LM2596HV Power Module

The plug-in LM2596HV, high-voltage version of LM2596 is used, the maximum input voltage is 50V (limited by the withstand voltage of the filter capacitor), and the external heat sink can withstand high current operation. The input terminal adopts a 4A rectifier bridge stack to input AC power, and has a dedicated DC input port, which is generally used for AC and DC input. The output voltage can be adjusted, ranging from 3.3V to 33V, and the output voltage will vary with different input voltage ranges.

The input AC voltage is AC5V~AC30V or DC5V-48V. Due to the large fluctuation of the AC voltage, the recommended AC voltage range has been reserved. The power module adopts the plug-in LM2596HV with heat sink, the high-voltage version of LM2596, the maximum input voltage is 48V (limited by the withstand voltage of the filter capacitor) with heat sink, the output current can work stably at the output current of 2.2A for a long time, It can work at an output current of 3A for a short time. The name of the terminal is printed on the front of the PCB, and the name of the terminal is also printed on the back. When soldering the leads, please recognize them before soldering to prevent damage.
