c) Maximum Power Rating
The decade has a total maximum power rating of 3 Watt.
The maximum power rating shall not be exceeded, as damage or even destruction of
the decade may occur.
Limit applied voltage in relation to maximum activated resistor according to table 1.
DO NOT APPLY ANY voltage to the decade without activated resistor !
This may lead to immediate destruction of the decade and in combination with high
voltages even to personal injury !
The maximum operational voltage V
maximum power rating of 3 W is calculated in the following way with the maximum
activated resistor R
