Hi,
Will need something for heat treating knives, steel stamps and similar and was looking at aliexpress 2500w zvs induction heater boards. As i have pretty clear about the boards which are 2200 3000 4000 and 5000 w at 48VDC , when coupled with second hand PSUs from China, the shipping and eventual customs will be quite steep.

So the Chinese use some 3000w power supplies made for servers and sell them for 80e and for the 2500 board i need 1x and for the bigger boards i will need 2x

Problem, in Spain or ebay EU could not find similar for that money and i really would like to buy the 4kw heater board as its best price/money

In USA i found people use 6kw cisco PSU for server giving 54vdc, sells cheap there/ 20-50e/, but no luck here in EU.

Any ideas welcome how to power cheap that setup so i decide what board to buy? There must be something available here which people dont know that could do that and for cheap
