Technical data of the H6 rectifier modules
1)
The max. surrounding temperature T
a
= 30°C must be maintained for the air-cooled version.
2)
IT system application only upon request.
3)
Limitations: The thermal dimensioning of the heat sinks is based on the rated current and the maximum permissible ambient tempera
-
ture. At high ambient temperatures and / or high heatsink temperatures (for example, due to a preceding utilization nearby 100%), the
drive converter can change to over-temperature error before the protective function OL is triggered.
4)
Input current, if no digital input is set. At max. load at the digital outputs the input current can be increased up to max. 1 A.
