Note:
RCWV (Rated Continuous Working Voltage ):
The DC or AC (rms) continuous working voltage corresponding to the rated power is determined by the following
formula:
V=√(P X R)
or max. working voltage whichever is less
Where
V=Continuous rated DC or
AC (rms) working voltage (V)
P=Rated power (W)
R=Resistance value (Ω)
