Active Energy Management Devices with internal storage

The PxtKX device is KOCH’s newly developed short-term UPS (uninterruptible power supply). The DC power source is designed for occasional use in the event of voltage dips and power failures. Connected directly to the DC link of the frequency converter or servo controller, the device responds immediately and without delay to a voltage drop, ensuring that the drive can continue to operate without interruption. With optimized power electronics and proven storage capacitors, the PxtKX offers an economically attractive solution for the increasingly frequent “worst-case scenario” of weak power grids.

The active devices designated PxtKX are supplemented by the PxtCX, the modular storage unit with one or more aluminum electrolytic capacitors.
