Overtemperature and continuous power at 100% duty cycle
If your application requires a higher continuous power than the specified nominal capacity, you can accept this state if a higher brake resistor temperature is permitted. The following diagram shows the overtemperature v. the continuous power.
|
Normal operating range, |
Permitted operating range, |
Inadmissible operating range, |
|---|---|---|
|
This operating range is recommended for maximum service life and error-free operation. |
This operating range is still permitted, although it results in shorter service life with higher failure probability |
In this operating range there is a risk of destruction of the brake resistor through overheating. Due to the high temperatures the adjacent components are also at risk. |
Always ensure adequate ventilation of the brake resistor, since the temperatures of the housing surface may exceed 200 °C.
