- Confirm the 100 A maximum-current class together with the 80 A rated input and 75 A rated output values
- Size the mains choke for the required DC-bus duty: 43 kW with the assigned choke or 24 kW without it
- Match the NNBV power-supply option, separate control section and external braking resistor before replacement
HCS03.1E-W0100-A-05-NNBV is a Bosch Rexroth IndraDrive C HCS03 compact converter power section for a single axis.
This air-cooled IP20 unit connects to 400–500 V three-phase mains, provides 73 A continuous output at 4 kHz and 50 A at 8 kHz, and incorporates a braking transistor with internal or external 24 V control-power capability.
Before commissioning, verify the assigned mains choke and fuse, braking resistor, cabinet cooling, motor connections, control-section identity and saved drive parameters.
Availability, condition, price, and shipping time for HCS03.1E-W0100-A-05-NNBV are confirmed during quotation.
