Underslung Converter 100kVA IGBT based for Metros.
Compliant Standards: IEC 61287-1 (Edition 2.0), IEC 60571 (Edition 2.1), IEC 60310 (Edition 3.0), IEC 61373 (Edition 2.0) and other relevant IEC and Indian (BIS) standards.
Technical Features
State of the art DSP based system.
Stabilized and balanced three-phase, 415V, 50Hz output, with low current distortion.
Balanced output eliminates the need of special auxiliary motors thereby reducing the cost of auxiliary motors.
Wide DC input variation (500 - 990 VDC) including 4.5% ripple and safety margin.
Maintenance free, being fully static.
Low noise level.
Underslung structure with IP65 protection class.
Online monitoring.
Event and Data logging facility.
Natural cooled.
Applications
Converts third rail DC input voltage with wide variation to stabilized three-phase, 415V, 50 Hz voltages for safe and reliable operation of electrical equipment roof mounted package unit (RMPU's) metro vehicles.
