Hi Rob
Yes we've used these on our SCBU transport system it comprises of a 300w inverter that powers a 6 way IEC outlet block to power an ECG monitor, pulse ox and a few syringe drivers. This system seems to work ok and has never given us any problems, mainly I guess due to the 6 way block, as there is only the option to plug the few leads into it that we have supplied.
Inverter - Mascot 9985 300W , RS 363-5306
Hope this is of some use.
Matt.
