height In the case of air cooling, it must be noted that the effectiveness of the cooling
is reduced the higher up the device is installed. As a result, the current carrying
capacity of the SCR power controller decreases with such a cooler as the in-
stallation height increases as shown in the image.
A
Destruction through overheating:
In the event of operation over a long period at maximum load current, the cool-
ing body and its environment heats up.
For this reason, at ambient temperatures above 45 °C, the maximum load cur-
rent must be reduced as shown in the image, as the SCR module would other-
wise be destroyed.
The device temperature shown on the display may not exceed 100 °C.
At a device temperature of > 100 °C, the message "Attention! High tempera-
ture" is displayed.
At a device temperature of > 105 °C, the output level is gradually decreased by
10 °C for each increase in temperature of one degree.
At a device temperature of > 115 °C, the power controller is switched off en-
tirely.
