Frequently asked questions
What input voltage do I need for my LED string?
The listing states the input must be 2 to 3V higher than the total LED voltage for the module to regulate. Choose an input voltage within 5-35V that meets this margin.
Can I dim the LEDs?
Yes, the listing states PWM dimming is supported. Check the dimming pin labels on the module before connecting a PWM source.
