Full digital energy-saving IGBT intermediate frequency series products
1, wide frequency range, 300HZ-15khz, starting frequency and highest frequency, lowest frequency can be set.
2, the fault detection and protection function is complete, all kinds of fault causes are displayed on the screen, and there can be indicator light indication, or synchronous output relay signal, for external system coordination.
3, friendly man-machine interface, man-machine interaction can choose a variety of ways, such as LED indicator light, digital tube display, text screen display, touch screen display and control, customers can choose according to their needs.
4, hardware isolation interface, reserved isolation of hardware input and output interface, can be compatible with the existing PLC market, beneficial to customers on the existing PLC system for functional transformation and further expansion of automation system.
5, 4-20mA (or 0-10V) interface, can support closed loop control with external systems, such as temperature closed loop control system.
6, save 10%-20% electricity (about 50-100 kilowatt electricity) than the traditional SCR if.
7, traditional SCR medium frequency harmonic is large, serious pollution to the power grid. IGBT intermediate frequency is a constant voltage source with low harmonics and no pollution to power grid.
