Will a 3CH Easy DMX board run at 31V?

[DavidJ247]

Looking for some advice, I have a 3ch DMX board from Ray Wu

which is listed as 5-24V, the lights I want to control need around 31V. Could this board take a higher voltage or is there a modification I could do to allow for 31V?

The regulator should be good up to 35V and the electrolytic capacitor on the plug side of the regulator is rated at 35V so you shouldn't have any problems there with 31V. I have no idea what the mosfets are but I would suggest that they would likely be rated to 40V or more. Without having 1 of the boards on hand to confirm I'd be reasonably sure that these would be good up to 31 with no issue. I would check that the heatsink on the regulator doesn't get too hot but I doubt it would.

Thanks Alan, much appreciated. The mosfets are WS108P, I see from a previous thread that these are equivalent to the ones used on the 27ch boards and the replacement ones you stock. There is no heatsink on the regulator (it uses a different part to the one pictured on Ray's site), I'll keep an eye on this for heat.
