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
