Features

1  High-to-high transform2  Special wind channel design for Air cooling3  Unit modularization design.4  Friendly interface 5  Reliability5.1  Optic fiber used for communication between units and controller.5.2  Redundant hot-spare design of units.5.3  PLC used for monitoring.5.4  IGBT,rectifierand filter capacitors in main circuit have high quality. 6  Flexible user interface can be configured in hard-wiredway or communication way. 7  High efficiency, high power factor Machine efficiency> = 98%, power factor> = 95% 8  Low harmonic When six units are cascaded in each phase, 36-pulse rectifier is applied for each phase. High-frequency carrier ratio makes output harmonic <4% when no-load, <2% when loading. 9  Wide voltage input range HVF runs reliably with input voltage fluctuating from 85% to 115%, frequency from 45Hz to 55Hz . 10  Small dv / dt 11  Module redundant hot-spare technology 12  Unique unit bypass technology

13  Line voltage auto-balanced technology 14 Instantaneous power-down without interference 15  Dual-power switch for control circuit

16  A unique over-voltage protection technology 17  Bypass cabinet (optional)
