Ensure safe DC-grid selectivity

VACON® NXP DCGuard™ enables fast disconnection and full selectivity be­tween DC grids for all VACON® NXP series drives.

Utilizing DC grids rather than AC grids enables power distribution with lower power losses. However, ensuring selectivity and limited short circuit energy requires more sophisticated protection devices.

VACON® NXP DCGuard is a semiconduc­tor protection device that maintains the stability of the DC grid by detecting and cutting off any faulty DC currents, fast. It isolates the faulty part of the system within 5 microseconds, protecting the surrounding equipment and ensuring uninterrupted operation.

It has DNV-GL, ABS, and Lloyd's Register type approvals, simplifying system approval for use in marine environments.

Current range

  • 465-800 VDC………3-4140 A
  • 640-1100 VDC…..….4-3100 A

Features and benefits

Correct system selectivity due to short circuit protection

No overvoltage spikes at current cut-off

Connect two different DC grids with voltage differences up to full DC voltage, thanks to controlled voltage ramp-up

Transmission cable overload protection

Reliable, proven technology
