Autometers Alliance Ltd has developed 25 KVA Under Slung IGBT-Based Static Converter for Head-On-Generation in technical collaboration with Hyundai Heavy Industries, South Korea. The converter employs state of the art DSP control and feeds the stabilized power to air conditioning and other loads of the railway passenger coaches. The product has been built in accordance with IEC 60571, IEC 61287-1 and IEC 60310. |

- Under carriage mounting of converter saves space for 2 extra berths inside the coach, enhancing revenue earnings.
- Under carriage mounting also prevents noise pollution, adding to passenger comfort.
- Sturdy MS sheet fabricated enclosure, with special protective surface treatment, makes it ideal for under carriage mounting.
- IP 65 protection makes the enclosure impervious to water, even in flood situations.
- High efficiency leads to low power consumption.
- Being naturally cooled the converter does not require any moving parts for cooling. This enchances life and reliability.
- Vacuum pressure impregnation using 'H-class' resins for filter inductors makes it ideal for traction duty.
- Maintenance free, being fully static.
- Converter's modular design makes it easily accessible through side panels and affords easy maintenance.
- State of the art DSP based system.
- Fault logging facility for ease of maintenance.
- Data transfer through serial communication between onboard display and under slung converter.
- Control and monitoring through onboard interactive VFD panel.
- PC interface facility for downloading of logged data and online monitoring.
Applications
- Converts single phase AC available from the locomotive transformer into 3-phase 415V, 50 Hz supply.
- Feeds 3-phase power to the loads, viz., air conditioning, lights, ventilation, pantry, and the like of the passenger coaches.
