Product Description:
The 176F3031 is a printed-circuit assembly supplied by Danfoss for the VLT PowerCards series of medium- and high-power AC drives. Within a compatible VLT drive, this card forms part of the power module that channels DC-link energy to the inverter section for pulse-width modulation of large induction or synchronous motors used in industrial automation. It is intended for applications where the drive must deliver controlled motor current to demanding equipment over long operating cycles. The board is used inside the drive rather than as a standalone controller, so it works with the surrounding rectifier, DC-link, and inverter hardware already present in the system. By using this card in the correct platform, the power stage can be restored without replacing the entire drive cabinet, which keeps the repair focused on the affected assembly.
The assembly is rated for 400 V nominal line potential, which suits common three-phase mains used in industrial facilities and HVAC systems. A rectifier topology with 12 pulses reduces harmonic distortion on the supply, and the card supports drive outputs up to 1000 kW for large compressors, conveyors, and chillers. The 12-pulse arrangement also helps reduce the burden on the incoming supply compared with simpler front-end configurations. Its mass of 2.5 kg affects handling and mounting, and its installed volume of 14.54 dm³ requires enclosure space with enough airflow to limit hot spots. These electrical and physical values place the assembly in drive sections that manage substantial power flow rather than low-energy control circuits.
Classified as a Power Card, the unit contains gate drivers, snubbers, and monitoring points that interface directly with the main control board of the drive. Support through DrivePro Services can include condition reporting and life cycle tracking for the installed assembly. Its direct electrical connection to the power stage means insulation spacing, signal coordination, and thermal layout must remain matched to the host drive design. This arrangement allows the card to operate as an integrated part of the inverter supply path while maintaining the clearances needed for safe operation at the stated voltage and output level.
