Product Description:

The 176F2128 is a dedicated power card manufactured by Danfoss and supplied within the VLT PowerCards series. Used inside high-power VLT drives, the module forms the interface between incoming three-phase mains and the inverter stage, where it supports the controlled DC link required for variable-speed motor control in industrial automation equipment. It combines gate drive, current sensing, and protective functions on one assembly, reducing the number of separate internal components that must share the same power path. This arrangement supports stable power conversion in large drive systems used for demanding motor applications.

As a power card, the unit is delivered ready for direct insertion onto the main bus bars of compatible frames. This direct fit helps keep the current path short and mechanically secure inside the drive. Its circuit side has a protective coating that helps shield components from moisture and conductive dust in industrial environments. The card is intended for 400 V mains, and its copper planes plus laminated tracks are sized for drive systems up to 450 kW without excessive resistive loss in the current path. Even with that capacity, the assembly occupies only 14.586 L, which helps preserve cabinet space in high-power installations.

The handling mass of 2.5 kg keeps the module manageable during installation and removal inside large drive enclosures. System compatibility is maintained through the VLT card format, so the board uses consistent signal headers and mounting points across compatible frame sizes. That common layout helps the card align correctly with surrounding bus structures and control connections. It also helps keep internal routing orderly where high-current sections and low-level control circuits must remain clearly separated. The module is intended for drive cabinets that need dependable electrical integration and a board layout matched to established VLT platform geometry.
