More than 10 years after the introduction of the DEx regenerative energy storage modules, Koch presents its successors in the form of the PxT modules Both a shortage and a surplus of DC energy in electric drives is actively managed, independent of the grid.
The internal power electronics can handle larger currents, the storage media has an enlarged storage capacity and the voltage range is wider, allowing even more frequency and servo controllers to make use of active DC DC DC DC DC intercircuit energy management in the event of excess or just additional electrical energy requirements.
The function of the PxT modules include:
- reuse of braking energy: up to 40% energy efficiency increase
- energy boost: faster acceleration and braking, this shortens cycle times and brings up to 50% output increase
- UPS function: compensating for voltage dips or the safe and defined standstill in the event of power loss
- UPS function: able to operate independently of mains connection, e.g. interrupted supply rail of an AGV
- peak-shaving: elimination of peak load on the grid, longer lifetime of controllers, smaller connection values, reduced standing charges
In addition to improved electrical properties, the PxT modules also offer more flexibility, on-board intelligence, status readout and communication interfaces that allow smarter applications without additional control logic. As before, Koch's modules remain plug-and-play and linkable with servo controllers and frequency inverters using only 2 or 3 wires.
