Feature: 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. 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 chip can withstand a large current of 3A, and can work at an output current of 3A in a short time) Output Power: 35W. Package List: 1 x Power Module Note: The front side of the PCB has the name of the silk‑screened terminal block, and the back side also has the name of the silk‑screened terminal block. Please recognize and re‑solder to prevent damage when soldering the leads.
