By 2032, the telecom power systems market is expected to be dominated by the DC power technology type, with a 64.5% share.

The compact, 2 kA 8/20 μs rated, surface-mount package series allows electronics designers to achieve a more robust transient voltage, overvoltage protection, and lightning protection system while using less printed circuit board (PCB) space.
 

Unlike a fuse, the VACON NXP DCGuard can easily be reset and restarted once fault conditions have been removed. This will remove barriers for end users who are reluctant to switch to more efficient DC systems due to concerns over short circuit fault currents.

The Vacon NXP DCGuard is a device that maintains the safety and stability of a DC grid system by detecting and cutting off any faulty direct currents (DCs) within 50 microseconds and, thereby, protecting the surrounding equipment by preventing brownouts associated with typical fuse or breaker protections that take up to 100 times longer to trip.

The module’s design is optimized for I.P.-sealed applications in high-pollution environments or externally mounted systems, which require solutions that are thermally bonded and contact-cooled to a cold-wall or heatsink. This results in 100% available output power at baseplate temperatures as high as 100ºC.

The three ports (two AC and one DC) built into each hot-swappable module can function as input and output. 

The PSC Family has a universal input voltage range of 85 V to 264 V AC, and output voltages of 12 V, 24 V, and 48 V DC.
