Toshiba provides auxiliary power supply units (APU) featuring compactness, light weight, low noise and high performance. These APU's are directly fed from the high voltage input catenary or third rail system and provide power for specific loads, such as air conditioners, heaters, lighting and propulsion blowers.
These auxiliary inverters are based on IGBT technology and cover a range of outputs up to 210kVA per unit.
In addition to the static inverter (SIV) with AC output, Toshiba also manufactures auxiliary power supply systems with DC output or combined DC/AC output.
Redundancy can be accomplished by providing a dual mode inverter – auxiliary unit. For more information on Transportation Systems Division click here.
