EL9570 | Beckhoff Buffer Capacitor Terminal

The EL9570 buffer capacitor terminal contains high-power capacitors for the stabilization of supply voltages. The EL9570 can be used in conjunction with the EL7041 stepper motor terminal, the EL7342 DC motor terminal and the EL7201 and EL7211 servomotor terminals. Low internal resistance and high pulse current capability enable good buffering in parallel with a power supply unit. Reverse currents are stored, particularly in the context of drive applications, thereby preventing overvoltages. If the recovery energy exceeds the capacity of the capacitors, energy can be dissipated via an external brake resistor.
