Features
1.   High-to-high transform
2   Special wind channel design for Air cooling
3  Unit modularization design.
4  Friendly interface
5  Reliability
5.1  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> = *8%, power factor> = *5%
8  Low harmonic When six units are cascaded in each phase, **-pulse rectifier is applied for each phase. High-frequency carrier ratio makes output harmonic <4% when no-load, <2% when loading.
9  Wide voltage range HVF runs reliably with voltage fluctuating from *5% to **5%, frequency from *5Hz to *5Hz .
*0  Small dv / dt
*1  Module redundant hot-spare technology
*2  Unique unit bypass technology
*3  Line voltage auto-balanced technology
*4 Instantaneous power-down without interference
*5  Dual-power switch for control circuit
*6  A unique over-voltage protection technology
*7  Bypass cabinet (optional)
