KL9570 | Buffer capacitor terminal
KL9570 | Buffer capacitor terminal
The KL9570 Bus Terminal contains high-performance capacitors for stabilizing supply voltages. The KL9570 can be used in conjunction with KL2531/KL2541 stepper motor terminals and KL2532/KL2552 DC motor terminals. 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, thereby preventing overvoltages. If the regenerative energy exceeds the capacity of the capacitors, energy can be dissipated via an external braking resistor.
