2 SOLAR ENERGY SYSTEMS DC POWER RELAYS - FTR-J2 Solar energy systems Relays FTR-J2 Ultra small high voltage DC relay Fujitsu Components recognizes the value and importance of protecting the global environment and strives to contribute to the creation of a sustainable environment for future generations. Not only does Fujitsu endeavours to reduce the environmental impact of the products throughout the product lifecycle, but also designs its products for integration in environment improving appliances. Fujitsu Components product range contains power relays that are highly recommended to be used in solar energy systems. With its current relay product range Fujitsu Components Europe has the opportunity to provide multiple solutions for solar energy systems. Fujitsu s solar relays have two target functions within the solar converter. The DC relays, to switch on/off the DC voltage generated by the solar panel, and the AC relays with big contact gap, to switch on/off the provision of the generated electricity to the power grid. This guide gives an overview of Fujitsu s relay product line up applicable for solar energy systems and its key features. Fujitsu solar relays for a sunny future The FTR-J2 is one of Fujitsu s DC relays suitable to be integrated in the solar converter to switch on/ cut off the DC voltage and current generated by the solar panel. The FTR-J2 relay is capable of switching 450V DC, 10A. Although the relay s capability to switch these high voltages, the relay dimensions are relatively small, the relay measures just 24mm(L)x 23.5mm(W)x27 mm(h). To be able to switch high DC voltages in these small dimensions, Fujitsu has designed two strong permanent magnets in the relay. This magnetic provision is installed to extinguish the severe breaking arc. These two magnets ensure the safe breaking of the DC current. The FTR-J2 is the powerful, compact and reliable solution for solar appliances that need to switch high DC voltage and current. The FTR-J2 is a 2 Form A relay that can be used in two different configurations. It can be used in a circuit in a configuration switching 2x200VDC and in a configuration switching 1x450VDC. The FTR-J2 can handle an inrush current of 150A (capacitive load). It offers high insulation between contacts and coil with an insulation distance of clearance/creepage > 6mm, a dielectric strength of 4,000VAC and 10,000V surge strength.

The FTR-K2W enables remote switching and emergency cut-off of the solar panel. The relay is capable of switching 60V DC, 30A.

3 DC POWER RELAYS - FTR-K2W AC POWER RELAYS - FTR-F4G FTR-K2W DC relay with 2x3.2 mm contact gap FTR-F4G Relay with contact gap The special feature of the FTR-K2W DC relay is its big contact gap of > 6mm. This double contact relay is designed with a total contact gap of > 6mm. The FTR-K2W enables remote switching and emergency cut-off of the solar panel. The relay is capable of switching 60V DC, 30A. The high insulation that the FTR-K2W offers, is shown in the relay s insulation clearance >8.0mm/creepage >9.5mm, the dielectric strength and the surge strength of. Like the FTR-J2, the FTR-K2W can be integrated in the solar converter to cut off/pass through the renewable DC energy. The very big contact gap and powerful switching capabilities classify this relay among the safest DC power relays. After introducing Fujitsu s DC power relay line up oriented on solar energy systems, the coming four pages will highlight the AC relays. These AC relays within Fujitsu s product line up are recommended to be integrated in the solar converter as a switch to turn on/off the provision of the generated electricity to the mains power grid. Fujitsu offers single side stable and latching type versions. First in line is the FTR-F4G, its main special feature is the contact gap of. According to the DIN safety standard VDE the circuit break function between the solar converter and the power grid must have a contact gap at each pole. For systems that provide full galvanic isolation; two relay contacts are needed. The FTR-F4G has a 2 form A contact configuration. Its switching capability of 250VAC, 5A makes the relay most suitable for the solar energy system type with low power requirements. The relay contact has TV3 inrush capability.

4 AC POWER RELAYS - K2G AC POWER RELAYS - K3-WG FTR-K2G Power relay with wide contact gap FTR-K3-WG FTR-K3 relay with big contact gap Fujitsu present the FTR-K2G. The relay has a contact separation of more than 3mm which provides a safe power switching between the mains power lines and the equipment providing full disconnection. The insulation distance between coil and contacts with a creepage of >8mm offers reinforced insulation. The FTR-K2G features a 1 form A contact and is capable of switching 5000VA with a max switching voltage of 440VAC. Besides these specifications, the relay has a high contact capacity of 20A. This powerful relay is recommended for the large solar panel systems. Further more has the FTR-K2G contact a TV8 inrush capability. The coil voltage ranges from 5 to 100VDC with a dissipation of 1W. The FTR-K2G relay has been designed based on the need of protection against hazards such as electrical, mechanical, thermal, fire and radiation of appliances when operated (complies with IEC ). Photovoltaic inverters Washing machines Tumble dryers Home entertainment systems Saunas Industrial power supplies Copiers (inter lock circuit) Fujitsu FTR-K3-WG features a big contact of. With this contact gap the relay complies with the DIN standard VDE for integration in solar energy appliances. The FTR-K3-WG is highly recommended to be part of the inverter function as a switch between the converter and the power grid. Compared to the early mentioned FTR-F4G relay, the FTR-K3-WG has a higher contact rating; 25A, 250VAC. Because of its high power the relay is recommended for the larger solar inverter systems. The FTR-K3-WG can handle a carry current of 25A. It offers high insulation between contacts and coil with an insulation distance of clearance > 6.5mm / creepage > 9.5mm, a dielectric strength of and 8,500V surge strength.

5 AC POWER RELAYS - FTR-K3-PV AC POWER LATCHING RELAYS FTR-K3-PV 32A high contact current relay FTR-K3 LATCHING RELAYS Eco-friendly & energy saving relays The FTR-K3-PV can also classify itself among the Fujitsu relays that are suitable for integration in solar energy systems. This AC power relay stands out through its high contact current of 32A. Same as the FTR-K3-WG solar relay the -PV version of this series has a contact gap of (complying with the DIN standard VDE for integration in solar energy systems). The surge strength between coil and contacts of this relay is 6,000V. The dielectric strength between open contacts is 2,500V/1 min. and 4,000V/1 min. between coil and contacts. The relay has a coil power consumption of 1,200mW. The coil holding voltage of the FTR-K3-PV can be reduced to 45% of the nominal coil voltage (ambient temp. +85 C, contact current 32A). The coil holding voltage contributes to energy saving of the application when using PWM coil drive. In an answer to the market demand for latching relays, Fujitsu released several new types. The market proven FTR-K3 series has been expanded with two latching versions suitable for solar energy systems; FTR-K3L-PV: The earlier mentioned FTR-K3-PV relay is available as a dual coil latching version. The relay offers a 32A high contact current and has a contact gap of. FTR-K3L-WG: Also the FTR-K3-WG has a dual coil latching brother. This contact gap relay has a contact rating of 25A/250VAC and can handle a carry current of 30A. Both relays feature a big contact gap which qualify them to be suitable for solar energy applications according the DIN safety standard VDE Solar energy systems Smart meters Copy machines Printers Power supply Latching relays offer low power consumption and low heat generation. An energy saving latching relay is cost efficient and at the same time eco-friendly.
