Product Description:

The HCS04.2E-W0520-N-04-DNBN belongs to the HCS IndraDrive Controllers series produced by Bosch Rexroth Indramat. As a drive controller, it converts and regulates electrical energy so that large synchronous or induction motors in automated cells receive stable torque and speed commands. The unit integrates the power supply, braking circuitry, and internal cooling hardware required for continuous plant-floor service. This configuration suits centralized drive cabinets that supply demanding motion axes with frequent acceleration and braking cycles. It is intended for applications where high power density and integrated braking support are required in one controller.

An output stage rated at 366 A allows the device to energize high-current motor windings, while its apparent power ceiling of 268 kVA sets the maximum electrical load that may be delivered at 400 V. The DC bus network stores energy in 10.4 mF of capacitance, smoothing regenerated voltage and supporting ride-through during brief mains dips. Mechanical integration of brake hardware is supported by a connection flange that tolerates up to 24 Nm of tightening torque, helping maintain low-resistance joints for the optional braking resistor. Thermal management relies on an internal blower that moves 800 m³/h of air through the IP23 pathway, and a 4 kHz switching clock helps limit semiconductor temperature rise when the 110 kg frame is mounted in a crowded enclosure.

During deceleration, energy is bled through a minimum external resistor of 1.75 ohms, and the circuitry can absorb 240 kW for ten seconds or 120 kW continuously without exceeding its operating temperature limits. Continuous conversion losses reach 4450 W, a figure that must be considered when sizing cabinet ventilation. The controller typically pairs with motors around 200 kW, matching its rated power to plant conveyors, presses, or extruders. Acoustic output is measured at 72 dB(A) one meter from the housing, and the infeeding and fed supply topology permits multi-axis DC-link sharing. The housing is also built to withstand mechanical shocks of 4 g for 11 ms during handling and machine operation.
