CALIFORNIA, US: Fujitsu has put out new offerings like FTR-J2 and FTRK2W relay as a solution to enable remote switching and emergency cut-off of the solar panel. These relays, connecting the solar panel to the converter, are able to switch DC power.

As a press release shows, Fujitsu Components is focusing on reducing the environmental impact of the products throughout the product lifecycle. Fujitsu claims that at the same time it designs its products for integration in environmental improving appliances. Fujitsu Components product range contains power relays that are recommended to be used in solar energy systems.

"The FTR-J2 relay is capable of switching 450VDC, 10A. Even though the relay's capability is to switch these high voltages, the relay dimensions are relatively small. To be able to switch high DC voltages despite small dimensions, Fujitsu has designed two strong magnets within the relay to extinguish the severe breaking arc. As to the AC relays, the FTR-F4G with relatively lower power switching capabilities is recommended for the small solar panel systems, where the FTR-K2G is most useful for relatively large solar panel systems." The release adds.
