![EJ9576 | Brake chopper module](https://multimedia.beckhoff.com/media/ej9576-0000__web_preview.png)
The EJ9576 EtherCAT plug-in module contains high-performance capacitors for stabilizing supply voltages. The EJ9576 can be used in conjunction with the modules EJ7047, EJ7342 or EJ7211-0010. Low internal resistance and high-pulsed current capability enable good buffering in parallel with a power supply unit. Return currents are stored, particularly in the context of drive applications, thus preventing overvoltages. If the regenerative energy exceeds the capacity of the capacitors, energy can be dissipated via an external braking resistor. The corresponding threshold can be directly parameterized in the TwinCAT System Manager.
