I have designed a LED dimming control using 6 of the International Rectifier AUIR33401S Programmable high side switches. This device allows for PWM control of the high side of our 2' x 2' and 2' x 4' planar LED panels that are ceiling mounted (replaces florescent light fixtures). Also this circuit uses the AUIR33401S to limit current down to 4 amps DC. If there is a fault on in the circuit then the AUIR33401S will turn off. As soon as the fault is removed the the 24 VDC is turned off / on the device will work (like a resettable fuse). We have ETL listing on our planar LED panels and are preparing to submit our dimming control device to ETL for testing.
We power the above mentioned circuit using Meanwell 24 VDC, 25A power supplies. We use conduit to power supply NEMA housing to provide AC and we use conduit from the power supply housing to our above mentioned circuit (in a NEMA housing). The circuit splits the 25A into 6, 24VDC, 4A DC branches using the AUIR33401S.
My question is does this above mentioned circuit using the AUIR33401S programmable high side switches and limiting the current (a type of supplementary breaker) allow us to claim that we are now NEC class 2 at the ouput of each of the AUIR33401S?
Sorry if this is hard to follow - I am an electronic and software engineer and new to the NEC class 1 and 2 discussions. We have set up this design in our lab and verified that everything works as expected. But when we approached ETL they were confused as to how to classify our design and how to test.
Thanks for your inputs . . .

Bob
