More Information

Overview Manuals Supply Engineering Thermal Design Load Validation Application
  • Coordinate the 350 A maximum-current class with the 200 A rated output and 201 A rated input values
  • Design for 120 kW DC-bus power with the assigned mains choke or 100 kW without that choke
  • Validate the 250 A mains fuse, cabinet heat removal and regenerative braking duty before full-load operation

HCS03.1E-W0350-A-05-NNBV is the 350 A feeding converter in the Bosch Rexroth IndraDrive C HCS03 range.

It accepts 400–500 V three-phase mains, delivers 200 A continuously at 4 kHz and incorporates the NNBV control-power arrangement with an integrated braking transistor.

Before full-load operation, verify the mains supply, assigned choke, braking-energy design, cabinet airflow, control section, firmware, motor rotation and commissioned parameters.

Availability, condition, price, and shipping time for HCS03.1E-W0350-A-05-NNBV are confirmed during quotation.

Description
HCS03.1E-W0350-A-05-NNBV is a Bosch Rexroth IndraDrive C compact converter power section in the IndraDrive C HCS03 family.

Bosch Rexroth HCS03.1E-W0350-A-05-NNBV is an air-cooled IP20 HCS03 feeding compact converter power section for one axis, with a 400–500 V three-phase mains connection, an integrated braking transistor and internal/external 24 V control-power capability. The complete code identifies HCS03 series 03, design 1, feeding supply, internal-air cooling, 350 A maximum-current class, IP20, voltage code 05 and the NNBV option; the control section and any external braking resistor remain separate system items.

Before installation or replacement, confirm the complete HCS03.1E-W0350-A-05-NNBV type plate, separate control section, power and motor connections, cooling arrangement, firmware and commissioned parameters.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What upstream checks are essential before selecting HCS03.1E-W0350-A-05-NNBV?
Confirm the plant can supply the required three-phase voltage, short-circuit power, assigned choke, protective device and conductor size. The largest current code should not be selected only from motor peak current.
Can DC-bus and motor busbars from an HCS03 W0280 installation be reused with HCS03.1E-W0350-A-05-NNBV?
Only if their current and temperature ratings, cross-section, insulation spacing, mounting layout and connection hardware satisfy the documented W0350 requirements. Physical alignment alone does not establish electrical or thermal suitability.
Why must protective-earth bonding be reviewed for HCS03.1E-W0350-A-05-NNBV?
The high-power converter requires a low-impedance protective-earth and EMC path. Verify the PE conductor size, bonding surfaces, terminal condition, cabinet backplate bonding and motor-cable shield termination; do not rely on mounting bolts as the sole earth connection.
Can the motor cable for HCS03.1E-W0350-A-05-NNBV be extended without reviewing the output circuit?
No. Longer cable increases capacitance, reflected voltage, leakage current and EMC loading. Keep within the documented cable limits and add the specified output choke or filter when required by cable length, motor insulation or installation conditions.
Does NNBV make an external 24 V supply unnecessary for HCS03.1E-W0350-A-05-NNBV?
Not in every configuration. The integrated DC-bus-derived supply has application limits; the motor brake, selected control section and safety options can still require a correctly rated external 24 V supply.
Can motor-protection and current-limit settings from a W0280 project be retained when installing HCS03.1E-W0350-A-05-NNBV?
Not automatically. Revalidate the actual motor data, cable, overload duty, switching frequency, acceleration profile and mechanical limits. The larger power section must not be allowed to expose the existing motor or machine to excessive current or torque.
How can a poor high-current connection on HCS03.1E-W0350-A-05-NNBV be identified after replacement?
With power safely isolated, inspect the lugs, conductors and terminals and verify the documented tightening torque. During an approved controlled-load test, compare phase currents and terminal temperatures; abnormal heating or voltage drop can indicate a loose or damaged connection.
