Please note the current sensor is in the negative output (0v) because of this you must use all 4 terminals ,the –in and –out are not connected together as a common , i.e. the load must be connected to the output terminals not +out and – in

 

5v to 35v input

700 MA constant current output for driving  led’s in series or a 700 ma led display

PWM input a high on this input turns the display off ( 1v or greater) so can be controlled from a PWM pin on any arduino
