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 and ABS type approvals, which simplifies system approval for use in marine environments.
Current range
465-800 VDC………3-4140 A
640-1100 VDC…..….4-3100 A
VACON® NXP DCGuardTM Fact Sheet
Utilizing DC grids instead of AC grids can improve system efficiency and system footprint by up to 20%. And there is a significant potential for energy saving especially when combining DC grids, energy storage and/or variable speed generators.
