That's one of those critical locations when using a modern voltmeter. There is only a tiny current being drawn and the plate actually DOES operate at higher voltage than 48 volts. The discrepancy is in the old measurement method and documentation.
Even a 20k VOM is not enough to load it down to match the published voltages.
