Chassis mount power supplies are sometimes also called enclosed power supplies. We may be able to get the exact same unit to replace your failed unit, if not then we will suggest something which is as close as possible.
We would need to know:
- The voltage of the unit which has failed. This needs to be exactly the same and may even be multiple outputs.
- The current (Amps or A) does not need to be exactly the same but must be higher than the unit it is replacing in order to supply the current demand of the load
- The size of the new unit and any specific fixing points may need to be taken into account (these details are usually on the .pdf datasheet)
