Product Description:
The 176F2143 belongs to the VLT PowerCards series produced by Danfoss for use inside VLT drives that operate in industrial automation systems. This printed-circuit assembly acts as the internal power interface, distributing converted DC energy to the inverter section and coordinating current paths for the motor output stage. By replacing or upgrading the original card, maintenance teams can restore drive functionality without removing surrounding cabinet wiring, allowing quick recovery of conveyors, pumps, or other continuous-duty equipment.
The card is coded for supply grids marked 7 (525–690 VAC), so its track widths and components accommodate the insulation distances and surge ratings necessary for medium-voltage installations. It is designed for Three-Phase mains, matching the input structure of high-power VLT converters used on large induction motors. Rectification is organised in a 12-Pulse topology, which lowers harmonic distortion by phase-shifting twin six-pulse bridges; this reduces the size of line reactors and improves plant power quality. For electromagnetic compliance the assembly supports B-Type RFI hardware, meaning the copper planes and filter layout meet stricter emission limits than the basic A-Type variant. During handling and shipment the board and its protective carrier present a Gross Weight: 1 kg, enabling service engineers to pre-plan lifting or stocking requirements.
Once unpacked, the board’s Net Weight: 1 kg confirms that no additional heat-sink plates are needed, keeping mechanical stress on the drive chassis low. Its outline occupies only 14.235 dm³, so it fits the standard card bay without spacer modifications and maintains the designed air-flow corridor. The unique article number 5710107586653 assists inventory software in distinguishing this spare from earlier revisions. Because the circuitry is classified as a Power Card, technicians can swap it independently of control or keypad assemblies, completing power-stage refurbishment while leaving parameter memory untouched.
