Line reactors for Power Modules

3.1.1

Description

The line reactors limit low-frequency line harmonics and reduce the load on the
semiconductors in the Power Modules. A line reactor is not required where the effective
supply impedance equals uk > 3 %.

Safety information

Danger to life if the fundamental safety instructions and remaining risks are not carefully
observed
The non-observance of the fundamental safety instructions and residual risks stated in
Chapter 1 can result in accidents with severe injuries or death.
• Adhere to the fundamental safety instructions.
• When assessing the risk, take into account residual risks.
Risk of burns due to high surface temperature of the line reactor
The line reactors can become very hot. You can get seriously burnt when touching the
surface.
• Mount the line reactors so that contact is not possible. If this is not possible, attach
• To prevent adjacent components from suffering damage due to these high
