176F2126
by Danfoss
The 176F2126 belongs to the VLT PowerCards series manufactured by Danfoss. This unit is a power card that slides into the drive stack and routes DC-link energy to the output transistors, allowing the host inverter to convert fixed line voltage into variable-frequency, variable-amplitude power for industrial motors and process equipment.
The board operates on a nominal bus of 400 V, and its copper paths and semiconductor rating support up to 400 kW of motor power. All conductive surfaces are Coated to guard against moisture, flux residue, and airborne contaminants that are common inside electrical panels. Gross and net shipping weights are identical at 2.5 kg, so handling calculations are straightforward during field replacement. As part of the VLT PowerCards series, the module keeps the same mounting geometry and connector style used across multiple frame sizes, allowing a failed board to be exchanged without rewiring or mechanical rework.
The physical envelope of the assembly is only 14.079 dm3, permitting high-power density when stacked with control and filter boards. For inventory and logistics, the EAN-13 code 5710107586806 uniquely identifies this spare, reducing selection errors at service counters. Internally it is classed as a Power Card, meaning all high-current switching and snubber circuitry is located on the same printed circuit sub-assembly. Each card ships directly from Danfoss with a static-safe package and carries the precise test data needed for drive parameter cloning, ensuring that the replacement functions with the original timing and protection thresholds.
