Product Description:

The 176F2124 is a printed-circuit power module in the VLT PowerCards series produced by Danfoss. Installed inside large VLT variable-frequency drives, it channels DC bus energy to the inverter and reports fault data to the control stage, allowing the drive to run high-power induction or permanent-magnet motors used on automated lines. It forms part of the internal power path between the control electronics and the inverter section, where power conversion and protective functions are divided across multiple assemblies. The module is intended as an internal drive component rather than a standalone unit, so it must be fitted in a compatible VLT system.

With an associated drive rating of 355 kW, the card is sized for high-horsepower cabinets where switching devices must endure heavy current. Its nominal bus reference of 400 V matches standard three-phase mains used in industrial installations. This bus level supports the inverter section used in common drive cabinet layouts without requiring a separate transformer stage. A coated finish adds resistance to moisture and dust for panel-mounted operation. Classified as a power card, it carries gate drivers, snubber networks, and current feedback that link the control PCB to the IGBT stack. Despite these circuits, the assembly occupies only 14.358 cubic decimeters of enclosure space, preserving airflow for nearby heat sources and adjacent power components.

For inventory control, the unit carries EAN 5710107586820, enabling barcode tracking through warehouses and service depots. Shipping data list a gross and net mass of 2.5 kg, which keeps handling straightforward during storage and transport. The board arrives in antistatic film and molded inserts that protect solder joints during transit. Clear labeling helps distinguish the module from lower-capacity cards while it is in storage. The packaging format also helps keep the board stable before installation in the drive cabinet or in a stock location.
