Features:
In addition to being a 12 Volt DC variable power supply, this product has a buzzer to identify if a signal feed to its input is live, alternating or a modulated wave. It also comes with a DC pulse wave generator where you can tweak the duty cycle using the internal 100k potentiometer. The led indicators simplify for beginners in troubleshooting circuits. Blue led; If the power supply is offering any output voltage. Yellow led; the output result of the PWM using pin 4 and pin 2. Red and Green Led indicates active low and active high signals respectively using pin 5 and pin 2.
