DC-DC converter ...wiring and tolerance?

[VvvvvV]

I found some cheap unknown DC-DC converters rated 48/5/2A, they are the block type about 5cm² and with 4 pins...


is it possible to link the output pins in a series to make 10V?

are these things inherently flexible? what will happen to the output if I put a 36V current on there -I can afford to blow a couple up to find out ?

The outputs are isolated, so two in series should work.

A similar 48v to 5v converter I looked up can take an input of 18v to 75v, so 36v should work fine.

thank you so much! I just had a go at 36 the output is perfect, and in series as well! fantastic ...it is to put some lights on an electric bike

what would happen if I wired it to a voltage that was outside of specifications? for example too low or too high? Would it just be very inefficient or is there something I could measure to find out what the chips can handle?

Without knowing ANYTHING about them, there is risk of damaging them, but most of the bricks I have used will just shut off when the voltage gets too low or too high. A lot have their own built in protection for that type of thing.
