Autometers Alliance Ltd has indigenously developed 25 kVA Under Slung IGBT-based Static Converter in technical collaboration with Hyundai Heavy Industries, South Korea.
The technology has been exclusively customized by AAL for Indian Railways.Special features like: Thermal designs, ruggedized power supply for variations & EMI/EMC requirements, stablized sensing circuits,window based MMI designs,Enhanced life for input MCCB by way of limiting its function only under fault conditions and permanent switch off has been added to make the product more viable.
The product, exclusively developed for railway passenger coaches, has been accorded 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 treatement, 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 interactive VFD panel.
- PC interface facility for downloading of logged data and online monitoring.
Applications
- Converts 110V DC supply of the coach batteries into 3-phase 415V, 50 Hz AC.
- Feeds 3-phase stabilised power to the loads of the passenger coaches, viz., air conditioning, lights, ventilation, pantry, and the like.
- Coach wheel/axle driven alternator rectifier system charges the batteries.
