How big is this device and what is your output voltage?
I think the 100-250V rating simply indicates that it can be used in most (all?) country power supplies, e.g. 110 in US, 240 in Aus, 220 in China, etc.
0.3A is the maximum current that can be supplied by the transformer. So, you can replace it with a similar DC plug pack that supplies 0.3A or more.
Geez, and here's me thinking any plug pack would do as long as it had the correct plug at both ends and was putting out at least .3A...

Take care when stating 'maximum current' because it's different before and after the transformation, which is why the 72VA would tell the story, not the 0.3A (unless we know the output voltage, which we don't yet).I hope it's resolved for you in any case, Phil. Watch ambient temperature for items installed in ceilings.
