1、Recommended Voltage: Input AC voltage AC5V~AC30V or DC5V‑48V. Due to the relatively large fluctuation of AC voltage, the recommended AC voltage range has reserved margin. 2、The high-voltage version of the plug-in is adopted, and the maximum input voltage is 50V (limited by the withstand voltage of the filter capacitor). With a heat sink, it can withstand high current operation. 3、Stable Current: The output current can work stably at an output current of 2.2A for a long time, and can work at an output current of 3A for a short time. 4、Universal for AC DC Input: The input terminal adopts a 4A rectifier bridge stack to input AC power, and has a dedicated DC input port, which is universally used for AC and DC input. 5、Adjustable Output Voltage: The output voltage can be adjusted, ranging from 3.3V to 33V. The output voltage will vary with different input voltage ranges. 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 chip can withstand a large current of 3A, and can work at an output current of 3A in a short time) Output Power: 35W 1 x Power Module
