Falowniki średniego napięcia do 15kV (XMV660) - Power Electronics
Standard Features
- Multi-grade rectification, low harmonic at network side, no need to add harmonic inhibitors.
- Higher input power factor, no need to compensate power factor.
- Output sinusoidal wave, no need to add wave filter, applicable to ordinary motor, longer cable can be used.
- Cell connected in series, low voltage component can realize high voltage output,€ voltage sharing on
components in series is not in place.
- Output sinusoidal wave, no need to add wave filter, applicable to ordinary motor, longer cable can be used.
- Cell can be by-passed or reduced. VFD is not shut down in case of partial fault. VFD is still operating with
derating.
- Direct high voltage output, no need to add output transformer
Advantageous Features
- VFD does not shut down when the main power is off within 3 seconds (non-standard configuration).
- VFD does not shut down when main power is deeply fluctuating within a short time (-35% within 20 seconds).
- VFD does not shut down when control power is off.
- Capable of receiving DC control power (non-standard configuration).
- Built-in PID regulator, doing a close loop control.
- Built-in PLC, seamless communication with working site.
- Nonlinear accelerating/decelerating function.
- When a given signal is cut off, rotating speed can be maintained.
- Auto-scheduling function
- Remote diagnosis and maintenance can be done through telephone network (non-standard configuration).
