Hey all,
I have purchased the LDD 1000H LED driver. Here's the datasheet:
http://www.meanwell.com/search/LDD-H/LDD-H-spec.pdf
I am using a 48V, 950mA SMPS to supply the driver, and I'm using a function generator to generate a square wave as an input to the PWM pin. Its currently loaded with two 27ohm (power resistors. When reading the output using an oscilloscope, I find that the output voltage is not periodically driven to 0V with the PWM signal, and it stays constant at 48V. Am I doing something wrong here?
Any help is appreciated
