  1.3  Rated power

Rated power is maximum power which can be continuously loaded at specified ambient temperature

70℃,as Table-1;however when the ambient temperature exceeds 70℃,rated power should be determined

from the derating curve of Fig.1.

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℃
