Maximum Power Rating
The decade has a total maximum power rating of
1 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
max
, which is allowed to be applied according to
maximum power rating of 1W is calculated in the following way with the maximum
activated resistor R
on
:
Table 1
