Adjustable Low Voltage Regulated Power Supply Module Buck DC-DC Power Supply Module 1. Recommended voltage: AC input voltage AC5V ~ AC30V or DC5V-48V. Due to the relatively large fluctuations in AC voltage, the recommended AC voltage range has a reserved margin. 2. The high voltage version of the plug is adopted, and the maximum input voltage is 50V (limited by the withstand voltage of the filter capacitor). With heat sink it can withstand high current operation. 3. Stable current: the output current can work stably at 2.2A output current for a long time, and it can work at 3A output current for a short time. 4. Universal for AC DC input: The input terminal adopts 4A stack rectifier bridge for AC power input and has a dedicated DC input port, which is commonly used for AC and DC input. 5. Voltage Adjustable Output: The output voltage can be adjusted, ranging from 3.3V to 33V. The output voltage will vary depending on the different range of the input voltage. Specification: Item Type: Buck Power Module Material: Plastic Electrical Parameters: Input voltage range: AC 5V ~ 30V, DC 5V ~ 50v Output range: DC 3.3V ~ 33V Output current range: large 2.2A (the voltage regulator microprocessor can withstand a current of large voltage 3A and can work at output current 3A in short time) Output power: 35W Package list oacute;w: 1 x power module Note: The front side of the circuit board is named terminal block with screen printing, and the back side is r oacute;also name clamp block with screen printing. Please recognize and re-solder to prevent damage when soldering the wires.
