Product Description:

The 176F3025 is a power-electronics sub-module manufactured by Danfoss for the VLT PowerCards series. Classified as a power card assembly, it plugs into VLT variable-speed drive racks and carries the gate-firing, protection, and feedback circuitry that steers the converter’s semiconductor devices. Its compact board layout eliminates the need for a discrete wiring harness and helps restore drive operation in industrial automation cells. Because these functions are consolidated on one board, signal routing stays orderly inside the converter and the installed assembly takes up little space.

The module is rated for a maximum bus potential of 500 V, so its copper traces, capacitors, and isolation distances suit half-kilovolt operation commonly found in 400 V-class motor drives. Its rectifier section uses a 12-pulse configuration, so input current is drawn in twelve symmetrical segments that reduce harmonic distortion and improve transformer utilization. The shipping mass is 2.5 kg gross, and the embedded copper planes and multilayer fiberglass help the assembly remain within the listed volume of 15.087 L. As an integrated Power Card, it has control connectors, snubber networks, and heat-spreader attachment points soldered directly to the board instead of using interposing cables.

The unpacked board has a net mass of 2.5 kg net, which indicates that no separate mounting hardware is included with the assembly. Inventory systems track the card under the European article number 5710107602209 for ordering and stock control. Its conductors use high creepage and clearance spacing in a printed-circuit format that supports the operating voltage while helping control EMI across the board surface. Balanced phase currents from the bridge are described here as input symmetry, a term used for evenly distributed input loading. This wording refers to the current pattern at the rectifier input rather than to any mechanical feature of the board.
