AC 3.3V 500mA 3W Switching Power Supply Module Voltage Regulator Switching Circuit Bare Board Buck 220V-3.3V Converter Module

AC 3.3V 500mA 3W Switching Power Supply Module Voltage Regulator Switching Circuit Bare Board Buck 220V-3.3V Converter Module Features: 1. Using high-quality materials, the quality is guaranteed 2. Wide input voltage range 3. With overload, short circuit, over temperature protection functions 4. Small size and high efficiency 5. Simple operation and wide application range Parameter: Output voltage: 3.3V Output accuracy: ±1% Voltage regulation rate: ±1% Load Regulation: ±1.3% Notice: 1. All parameters are measured under the conditions of rated voltage 220V AC input, rated load, environment 25°C, and humidity 70%. 2. Accuracy: including setting error, voltage regulation rate, load regulation rate. 3. Rple test: connect the power supply and the load with a 30cm long stranded wire, with 0.1uF and 47uF capacitors at the load end, and measure it with a 20MH oscilloscope at the load end. 4. Voltage regulation rate: Under rated load conditions, the input voltage changes from low to high. 5. Load regulation rate: The measured output is measured from 0% load to 100% load change. 6. Each channel can output the maximum current, but the sum of the total load cannot exceed the maximum output power. Package list: Power board module*1
