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 shall be compliant with the SELV safety standard defined in EN60950. The

supply voltage must be limited according to Table 20.
