1.4 Rated voltage

The rated voltage shall be the D.C. or A.C.(R.M.S. at power frequency) voltage which corresponds

the rated power and the value of which is calculated from the formula below.

E=√(P×R) Where E: Rated voltage(V)

P: Rated power(W)

R: Nominal resistance(Ω)

Operating Temperature Range:-55℃～+250℃
