Product Description:
The KCU02.2N-ET-ET-025-NN-N-NN-MW is a drive control supply unit from Bosch Rexroth Indramat and belongs to the KCU IndraDrive Control Systems series. In an IndraDrive cabinet it delivers auxiliary power to logic circuits, I/O modules, and safety relays, allowing the main inverter stages to concentrate on motor energy conversion while this module stabilizes low-voltage control rails. By separating control power from the high-power path, the product supports predictable start-up behavior and coordinated shut-down sequences required in automated assembly cells, packaging lines, and material-handling axes.
The unit provides a continuous output current of 25 A on its 42 V DC bus, with the bus potential held at 42 V and backed by an internal storage bank rated at 11 mF of input capacitance for ride-through during brief mains dips. Under nominal load the control section delivers up to 588 W while drawing 675 W from the supply, and it admits a maximum inrush of 10 A when the cabinet contactor closes. Forced-ventilation cooling removes the heat produced by semiconductors and magnetic components, and total power dissipation is limited so that downstream temperature management remains within envelope.
The control stage can tolerate peak demands up to 71 A for one millisecond, yet its steady losses are confined to 90 W, helping the 3.80 kg housing stay within component temperature limits set by the IP20 protection class. Overall rated power throughput for the associated drive combination reaches 18.8 kW, so cabinet layout must guarantee 110 mm of bottom clearance, 80 mm at the top, and no horizontal gap. Zero-millimeter side spacing simplifies densely packed multi-axis systems, while input capacitance and the 33 V one-millisecond ceiling voltage support safe low-energy disconnection procedures.
