Product Description:
The 176F3024 power card is produced by Danfoss and belongs to the VLT PowerCards series. As a replaceable printed-circuit assembly, it carries the high-current path inside large VLT drives by taking rectified line energy and feeding it to the inverter phase modules that generate motor voltage. The board works as part of the internal power conversion path, linking the front end of the drive to the output stage that supplies the motor. This arrangement allows one board to be replaced without removing the entire drive stack, while the original control electronics and parameter set remain in place. The card is intended for multi-megawatt compressors, pumps, and ventilation systems that require a compact power section inside the drive enclosure.
The card is intended for a mains system voltage of 500 V, so the surrounding protection and power components must be matched to that level. Its system power rating is 800 kW, which places it in large variable-speed drive installations used for heavy industrial loads. It supports a 12-pulse front end, which uses phase-shift transformer connections to reduce harmonic distortion on the supply network. That topology also helps limit line-current ripple compared with simpler rectifier arrangements. The assembly occupies 14.157 dm3 of cabinet space, which helps when arranging the internal layout of large drive sections and retrofit panels.
The assembly has a mass of 2.5 kg, so the static load on its mounting points remains modest for a high-power board. Its PCB assembly type is Power Card, which means the insulated-gate transistors and snubber circuits are mounted on one reinforced laminate rather than on separate heat-sink modules. Gross and net shipping masses are the same, indicating that the board is supplied without extra accessory hardware in the package. The compact layout keeps the power section concentrated in a single module and supports direct installation inside the drive frame. This format also helps keep internal connections short between the DC bus and the inverter section.
