Active inverter
cooling
The inverter's temperature-controlled, variable-speed fan with ball-bearing support pro-
vides:
- Optimal inverter cooling
- Higher efficiency
- Cooler parts, thus extending the service life
- The least possible energy consumption and lowest possible noise level
- Weight reduction due to the reduction of the cooling element surface
Power derating Should there be insufficient heat dissipation in spite of the fan operating at maximum speed
(for example, inadequate heat transfer away from the heat sinks), the power will be derated
to protect the inverter when the ambient temperature reaches approx. 40 °C and above.
Derating the power reduces the output of the inverter for a short period sufficient to ensure
that the temperature will not exceed the permissible limit.
Your inverter will remain ready for operation as long as possible without any interruption.
