FTR-J2 and FTR-K2W relays
Fujitsu Components has launched the FTR-J2 and FTR-K2W relays for use in solar energy systems.
The company said the relays provide 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.
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.
The relay measures 24 x 23.5 x 27mm.
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.
The FTR-J2 is a compact and reliable solution for solar appliances that need to switch high DC voltage.
The FTR-K2W DC relay is also suitable to be integrated in the converter of solar systems to switch on/off the DC voltage generated by the solar panel.
The main feature of this relay is its large contact gap of >6mm.
Furthermore the relay is capable of switching 60VDC, 30A.
Fujitsu's FTR-K2G, FTR-K3-WG and FTR-F4G relays can function as an interface between the solar converter and the power grid.
These AC relays can be used in compliance with DIN VDE 0126-1-1.
According to this safety standard the circuit break function between the solar converter and the power grid must have a contact gap >= 1.5mm at each pole.
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.
