High Voltage Frequency Inverter

* The harmonic wave of input current is small since the input terminal adopts multiple phase a shifting transformer. And the output wave approaches sine
* The system input is rectified and non-controlled with 6n pulse,i.e. 18pulse(T30),30 or 36pulse(T60),54pulse(T100). While the load output is of (2n+1) levels, i.e,7 levels(T30),11 o 13 levels(T60),19 levels(T100). Both the input and output approach perfection.
* Without installing filter the input and output harmonics can meet the requirement of IEC 61800-4:2002
* NO need to install power factor compensation device since the power factor is above 0.97 within normal speed regulating range and rated load.
* No particular requirement on the motor to be driven.
* Total system efficiency is above 96%.
* Friendly user interface: full Chinese. Windows 2000 operation system. Large display screen. Realcolor LCD display, direct operation with touch screen.
* Flexible control: local control by touch screen; remote control by I/O of built-in PLC ;Host control via RS485a s connecting to DCS system.
* High-power inverter prechaged circuit enable the system to start without impact. It is suitable to any low-capacity power gird and peripheral equipments.
* Two-way control power supply maximumly ensures the system normal operation..
