Mitsubishi Electric Expands Lineup of Integrated 400V AC-Output Station Energy Saving Inverter

Posted by fidest press agency su mercoledì, 29 novembre 2017

Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it would launch a new integrated Station Energy Saving Inverter (S-EIV®) with 400V AC-output for converting surplus regenerative energy from train braking intokyo-japanto AC electricity for station facilities. The new 400V AC S-EIV facilitates easy installations and more energy-efficient operations, even at train stations with high-load demands of 400V power distribution circuits. The company also announced that the new S-EIV will be installed at Tokyo Metro Co. Ltd. train stations serving urban Tokyo.The new S-EIV offers 400V AC-output with the same dimensions as its 200V AC predecessor. Also, its new multifunctional step-up transformer acts as a filter reactor to reduce harmonics in AC output. Front access for easy cabling and maintenance enables diverse installation options. Reliability has been improved by adding protection and monitoring functions. A new earth-fault detection circuit quickly identifies unexpected current flows to the earth via the unit’s enclosure due to degraded or damaged insulation, ensuring safe grid-interconnection and durability for outdoor, along with the enclosure’s dustproof, splash-resistant and rust-resistant design. Improved monitoring of main circuit devices and grid voltage contribute to system stability and easy maintenance.
