ACS 600 MultiDrive – Technical Data
ACS 600 MultiDrive A-23
Derating factor for degree of protection IP 21/22/42:
• Above +40 °C, the rated output current is decreased 1.5 % for every additional
1 °C (up to +50 °C).
• Example 1. If the ambient temperature is 50 °C the derating factor is
100 % - 1.5 · 10 °C = 85 % or 0.85. The output current is then 0.85 · I
2N
(or
