5 Electrical, Reliability and Radio Characteristics
5.1 Absolute Maximum Ratings
The absolute maximum ratings stated in Table 20 are stress ratings under any conditions. Stresses beyond any
of these limits will cause permanent damage to AC65/AC75.
The power supply connected to the AC65/AC75 module shall be compliant with the SELV requirements defined
in EN60950. Above all, the peak current of the power supply shall be limited according to Table 20.
