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.VACON® NXP DCGuard has DNV-GL, ABS, and Lloyd's Register type approvals, simplifying system approval for use in marine environments.Current range465-800 VDC………3-4140 A640-1100 VDC…..….4-3100 A
