Overview
Sinamics S120液冷驱动器专门
designed to address the requirements relating to liquid cooling;
它们的特征是高功率密度并优化
脚印。液体冷却可以更有效地散发热量
than air cooling systems. As a result, liquid-cooled units are much
more compact than air-cooled units with the same power rating.
由于电子组件产生的热量损失
are almost completely dissipated by the liquid coolant, only very
small cooling fans are required. This means that the devices are
安静运行。由于它们的紧凑尺寸和几乎
液冷单元是微不足道的冷却空气需求
在限制安装空间和/或
the ambient operating conditions are rough.
Control cabinets with liquid cooling are easy to implement as
密封单元具有IP55保护程度的密封单位。
产品组合包括以下液冷
Sinamics S120内置单元：
•
Power Modules
•
Basic Line Modules
•
活动线模块
•
