Coliao 3pcs AC/DC to DC Buck Converter AC Adapter 5-30V DC 5-48V 24V 36V 48V to DC 2.5-35V 12V Adjustable Voltage Regulator Power Supply Board LM2596HV 2A Voltage Converter Module

✹ The power supply uses the LM2596HV plug-in, which is the high-voltage version of the LM2596. The maximum input voltage is 50V (limited by the withstand voltage of the filter capacitor). External heatsinks can withstand high current operation. The input port uses a 4A rectifier bridge stacker for AC power input and has a dedicated DC input port that is commonly used for both AC and DC input. The output voltage is adjustable from 3.3V to 33V, and the output voltage varies with different input voltage range.

✹ The input voltage is AC5V-AC30V or DC5V-50V. Due to the large fluctuations in AC voltage, it is advisable to keep the AC voltage range. The maximum input voltage of the power supply is 50V (limited by the withstand voltage filter capacitor) and the heatsink. The output current can work stably at 2.2A output current for a long time and at 3A output current for a short time. Screen printed pin names are on the front of the circuit board and screen printed pin names are on the back. When soldering wires, mark and solder them to avoid damage.
