Product Description:
The HCS02.1E-W0054-A-03-NNNN belongs to the HCS IndraDrive Controllers series manufactured by Bosch Rexroth Indramat. As a drive controller, it regulates AC mains power, establishes a DC link, and modulates current for servo axes in automated machinery. This arrangement lets connected motors follow changing speed and torque commands reliably.
The controller handles a continuous output of 20.6 A at a 4 kHz PWM carrier and can deliver a device peak of 54 A during acceleration or brief shock loads. Supply lines from three-phase grids between 200–500 V AC ±10% are rectified and stored on a bus with 0.405 mF of capacitance. An internal blower moves air across heat sinks inside the IP20 enclosure, while rated DC operation draws 19 A and limits inrush current to 2.8 A.
Power handling starts at 1.5 kW and reaches a continuous 7 kW rating without a line choke, or 10 kW when a choke is added to reduce harmonics. Momentary output rises to 16 kW, and the energy module can dissipate braking through an external resistor at up to 18 kW. Output frequency extends to 1600 Hz at a 16 kHz carrier, and overall thermal loss is limited to 270 W during normal operation. The unit can function as either an infeeding or a fed power supply sub-assembly.
