One of our clients from German ordered some high voltage DC-DC converters, see below features.
PS: Currently there are few factories produce the input 100-1000V, and they use 210-1200V instead of such model, but we have kept 100-1000VDC series.
Mainly founction features

For better installation if you are the first time to use such kind of power module, may you find a documentation for typical application circuit below.
Our client asked that if there were capacitors on Input or output required?
Generally speaking, you can use our models for direct collection, but if you want the very lower ripple, then please add the capacitors at the input or output port.
If you have some more technical questions,welcome to write to us, thank you!
