Derating factors as a function of coolant temperature

SINAMICS S120 Liquid Cooled units are designed for cooling by H
Antifrogen N mixture. An H
Antifrogen N.
When H
between 5 °C and 45 °C. The maximum output current decreases linearly to 90 % at
temperatures between 45 °C and 50 °C.
When H
100 % output current at temperatures between 0 °C and 45 °C. The maximum output current
decreases linearly to 90 % at temperatures between 45 °C and 50 °C.
