High Voltage Medium Soft Starter And Variable Frequency Drive - China

price: contact company for price

Soft start function: Starting current less than rated current,

repeatedly start allowed.

Direct high voltage in- out power distribution: DLHVF high frequency- converting speed regulator is appicable for normal AC induction motor. It directly input and output high voltage electric power. No transformer is needed. The device occupies little area.

3. No harmonic input: HVFS device has utilized the phase shift multi- rectify technology, the voltage and current harmonic is low. There is no need to use harmonic control devices in the input progress, no pollution to power system.

4. No harmonic output: HVFS device output standard sine waves, the voltage and current harmonic is low. No harmonic control device is needed in output progress. It will not increase the motor noise and will not generate additional stress.

5. High security level: HVFS is designed following China high voltage peremptory norm, high voltage primary circuit and control circuit are connected by optical fiber.

6. Perfect protection and fault alarm design: HVFS has perfect system protection and power unit protection function. And after protection it will auto record and simulate the fault conditions. The fault record includes protection operations, starting and lasting time which can help the analysis and define of fault.

7. Great flexibility: HVFC device is real- time controlled by PLC( programmable Logic controller) . The control type settings can be convenient changed in human- computer interface. Variable standard communication protocol convenient for communication with center- control system.

8. Convenient installation, commission and maintenance: Drawer- type power unit, connect assembly for power unit and external wire. No manual connection needed and convenient to replace.
