Power Supply
Note that in order to comply with CE Low Voltage Directives
(LVD), you must use either a NEC Class 2, a Safety Extra Low
Voltage (SELV) or a Protected Extra Low Voltage (PELV)
power supply to power this adapter. A SELV supply must not
exceed 30V rms, 42.4V peak or 60V dc under normal
conditions and under single fault conditions. A PELV supply
has the same rating and is connected to protected earth.
