I am currently working on an LED powered flood light that can be controlled via an arduino. The problem I am facing is selecting the proper relay. I'm a programmer by profession and dabble in electronics as a hobby, so there's always the chance that I am overlooking something obvious, which might be the case here.
What I have is an led driver (110-220AC - 288v, 900mA DC). I figure there are two ways I can go about controlling this circuit with an arduino. I can either place a relay between the LED bank and the DC 288v side, or I can place a relay before the driver/powersupply and switch AC. However every time I find a relay I believe will work, one of the specs is off. Either it won't have a high enough current rating, or the max voltage will be too low. The closest one I have found is this guy here and I have a feeling I'm way off. It's only rated at 500mA which won't work as I'll be pushing 900mA, but another thing that caught my eye is that it says "maximum switched power: 10W". The circuit this relay would be responsible or controlling would be upwards of 200 - 230 watts, so I'm guessing this is a deal breaker as well?
What type of relay does one use to control a high wattage circuit with a low voltage micro-controller (in this case an arduino)?
