Working Voltage
Rated value
Explanation
The rated voltage of each resistance should be calculated from the equation
below. And when the rated voltage exceeds the maximum RCWV,
the maximum RCWV should be the rated voltage.
Rated voltage = (Power rating x Resistance Value)
The maximum RCWV : 15V
The overload voltage should be 2.5 times the rated voltage. And when
