Other high-current 48-Volt phantom powered microphones include models from CAD (Equitek) and some Shure KSM condensers, as well as the original AKG C 451 (not their modern-day "C 451 B" which is quite different). These would not be powered reliably by a supply that puts out "only" 5 mA/channel.
I have to put "only" in quotes because I well remember the 1970s, when typical 48-Volt phantom supplies could only put out 1 - 2 mA per channel.
