Features Product function: The power supply DIY kit suitable for DIY small circuit power supply, an adjustable signal generator output convenient to provide pulse signals to the experimental circuit, the logic pen tests the logic level, and the buzzer tests whether the circuit is powered on and low-frequency signals. Automatically Switch: The output current limit status is indicated by LED, when the output current exceeds the limit current, it will automatically switch to constant current mode to provide full protection against overload or fault. DIY Parts Set: The power supply DIYkit need to install by yourself, can exercise hands-on ability. First, weld small parts such as resistors and capacitors, which is suitable for electronic DIY enthusiasts to learn and practice welding. Output Voltage: High quality DC regulated power supply whose output voltage is continuously adjustable from 0 to 30V. If small voltage regulation range, check the R1 resistor for errors. Multifunction: The power supply DIY kit provide current limiting, LED display, overload and short circuit protection. All are in-line components, easy to install and maintain.
