Product Description:

The 176F2136 is a replacement power module manufactured by Danfoss for use in variable-frequency drives. It slots into the control section of VLT units and provides the insulated gate signals, snubber circuitry, and monitoring channels that allow the inverter to modulate motor voltage and frequency. By restoring these core switching functions, the card can return pumps, fans, and general conveyor equipment to normal operation without replacing the entire drive.

Inside drives rated up to 315 kW, this board conducts and conditions the DC-link energy that feeds the IGBT phase modules. Its 400 V voltage class matches common low-voltage mains, allowing one spare part to cover multiple cabinet variants. The assembly is supplied with a coated finish, so the copper traces and discrete components are protected by a conformal varnish against dust, salt, and periodic condensation. Danfoss identifies it as a Power Card, which means the high-current paths and snubber elements are concentrated on this printed circuit while signal processing remains on separate logic hardware. The module uses the edge connector and standoff pattern associated with the VLT PowerCards series, so it fits the intended mounting points without drilling or cable modification.

The board has a gross and net mass of 2.5 kg, which keeps handling straightforward and helps reduce the risk of accidental damage during installation. Its occupied volume of 14.235 dm3 allows it to fit inside the original plastic carrier while leaving space for airflow around key heat-spreading components. Clearly stamped identifiers such as the Power class and the Voltage class simplify warehouse sorting and help prevent the use of an unsuitable card during a hurried shutdown. This physical profile also makes the module easier to store and move within standard drive service inventory.
