Need programmable controller 48v 30a

[voilamart special]

Hello friends, I'm asking for your help finding me a programmable controller that does 48v 30a that allows me to set the voltage cutoff at 38v and 39v as an option.

Any help greatly appreciated. I don't care if you're a vendor or get a commission either - I just want a controller that does this and it's hard to get details without having them in one's possession

Thanks in advance.
