Why wont my 751 passive infrared sensor work, it has a 20W flood light wired to it?
The reason why the light/ sensor wont operate as deisred is because the minimum operating load is 40W. Due to the design of this sensor it is only capable of a maximum of 2 Amps and a minimum of 40W. It also has a maximum off-state leakage current of 5mA.
If any of these values are exceeded this may casue the system not to work.
