Using a SCXI Chassis (US model, 110V) in a Country with 220V Power Outlet Hardware: SCXI>>Chassis>>SCXI-1000, SCXI>>Chassis>>SCXI-1001
Problem: I would like to use a SCXI chassis (110v US model) in a country that has 220V outlets. Is this possible? Solution: Yes. The SCXI chassis does support being used with different power supplies. However, the main power fuse needs to be changed in order to support your different power supply settings. The label on the back of the SCXI chassis will describe the fuse specifications for different power supplied - with a 220V power supply NI recommends using "Littelfuse 218.250", which is a 250V 1/4A slow-blow fuse. If you try to use the U.S. fuse in the same chassis with the different 220V power supply setting, you will run the risk of damaging the chassis in the event of a voltage or current spike. Also, different fuse manufacturers have different surge withstand specifications for the same type of fuses, so if you choose to go with a fuse supplier other than Littelfuse, you should make sure that the Surge withstand (I2t) spec is at least as good as the littelfuse specification. Note: All SCXI-1000 and SCXI-1001 chassis have a tumbler on the back to change the power supply, and it is recommended to use this built-in converter over using an external transformer.
