SELV
Safe Extra Low Voltage:
Voltage, which, under all operating conditions will not exceed a peak or DC voltage of
42.4 V. This voltage is either measured between two conductors or between one
conductor and earth.
The circuit, in which this voltage occurs, must be separated from the mains power supply
by a safety isolating transformer or some equivalent.
