I've seen that on eBay ...
It uses the case for a heat sink, similar to the crappy BZ-500 ... a 30 amp controller requires a way to dissipate heat, the case won't cut it at full current with large Vin to Vout differences
It has a maximum input of 60V , pretty low for a 30 amp controller
looks like a one man shop, it might be a good controller, but nothing in the documents make it stand out, all the features are in current controllers that have more backing behind them.
