The power module adopts plug-in LM2596HV, high-voltage version LM2596. The maximum input voltage is 50 V (limited by the filter capacitor withstand voltage). The external heat sink can withstand high current treatment. The input terminal uses a 4A rectifier bridge stack for AC power input and has a dedicated DC input port commonly used for AC and DC input. The output voltage is adjustable from 3.3 V to 33 V and the output voltage will vary with different input voltage ranges.
Due to the large fluctuation of the AC voltage, the AC voltage AC5V-AC30V or DC5V-50V input has allocated margin to the recommended AC voltage range. The power module has a maximum input voltage of 50 V (limited by the filter capacitor withstand voltage) and a heat sink. The output current can run consistently at 2.2A output current for a long time and can operate at 3A output current for a short time. The front part of the pcb has the name of the silk screen terminal and the back side has the name of the silk screen terminal. When soldering the lead, please recognize it and solder to prevent damage.
