3.12.1 EL9570 ­ Introduction and Technical Data
Fig. 39: EL9570
The EL9570 Bus Terminal contains high­performance capacitors for stabilizing supply voltages.
The EL9570 can be used e.g. in conjunction with the EL7041 stepper motor terminal, the EL7342 DC motor
terminal or the EL7201 servomotor terminal.
Low internal resistance and high­pulsed current capability enable good buffering in parallel with a power
supply unit. Return currents are stored, particularly in the context of drive applications, thereby preventing
overvoltages. If the regenerative energy exceeds the capacity of the capacitors, energy can be dissipated via
an external ballast resistor.
