Our products manage the energy in your drive.

Active energy management devices and safe braking resistors for electric drive technology

Managing brake energy

Braking energy can be managed in a fast and direct way due to safe brake resistors. It can also be buffered in active energy management devices.

Increasing productivity

Active energy expansion of the DC link gives the drive more room for braking and acceleration cycles.

Bridging power failures

Short-term power failures are bridged by the energy stored for this case in the active energy management systems without the machine noticing anything.

Compensating voltage dips

Planned and unplanned voltage dips can be compensated with active energy management systems.

Reduce connected loads

Through active energy management devices these peaks are taken from the energy storage and the power supply is sized for the average power.

Increasing energy efficiency

Energy is saved by reusing braking energy for acceleration cycles.

Controlled stops in case of a power failure

In the event of a power failure, the system can be brought into a controlled state without causing damage to materials or machinery. Restarting is possible without any problems.

Enable starting of the drive controller

A drive controller is powered by a battery storage system. It isn´t possible to start the drive controller via the battery storage system. The drive controller is started via the resistor.
