Mitsubishi Electric Expands Lineup of Integrated 400V AC-Output Station Energy Saving Inverter
Will contribute to more energy-efficient operations, even at train
stations with high-load demands of 400V power distribution circuits
TOKYO–(BUSINESS WIRE)–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 into 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.

Specifications of New Integrated 400V |
|
| Input voltages | 1500V, 750V or 600V DC |
| Output voltage | 400V AC, 3 phases, 50Hz/60Hz |
| Rated output | 200kW for 30 seconds every 3 minutes |
| Cooling system | Self-cooling |
| Installation | Outdoor areas (end of platform or by rail tracks) or indoors |
Compared to 200V AC systems, 400V AC systems are deployed for
distribution circuits in stations with especially large loads to
suppress voltage drops and reduce distribution loss, to efficiently
power elevators or escalators. Due to its compatibility with 400V AC
systems, the new model does away with the existing 200V AC S-EIV’s
step-up transformer. The new 400V AC S-EIV will make it easier for
railway companies to adopt S-EIVs for stations with large loads.
Mitsubishi Electric’s new model and existing 200V and battery models
offer a wide range of solutions.
