4PCS LM2596HV AC/DC to DC Buck Step Down Converter Module 3V 3.3V 5V 6V 9V 12V 15V 24V DC 5V-50V Adjustable Step-Down 3A Power Supply Adjustable AC/DC to DC buck converter power supply module Voltage Regulator
Input AC voltage: AC 5V~AC 30V or DC 5V-50V. Due to the large fluctuation of AC voltage, the recommended AC voltage range has been reserved. The power module uses a plug-in LM2596HV, the LM2596 high-voltage version. The highest input voltage is 50V (limited by filter capacitor voltage) with an external radiator, and it can withstand high-current operation.
Input voltage range: AC 5V-30V, DC 5V-50V.
Output range: DC 3.3V -33V
