high-voltage frequency converter

High-voltage frequency converter product of our company

A.3KV high-pressured frequency changer (200-5000KW)

B.6 KV high-pressured frequency changer (200-5000KW)

C.10 KV high-pressured frequency changer (200-5000KW)

Technical features:
1. It is a unit series high frequency converter.
2. Design of modulization, with beautiful appearance and compact structure.
3. Small content of input and output harmonic waves, which little affects the power supply system and the motor.
4. High input power factor and no need for power factor compensation unit.
5. Sinusoidal output, which makes the operation of the motor even steadier.
6. Perfect function of trouble self-diagnosis. In the case of troubles such as short circuit, grounding, overcurrent, overload, overvoltage, undervoltage, overheating, etc., the system can timely protect or give warning.
7. Various frequency setting modes such as touch screen, digital keyboard, analogue, long-distance DCS, etc. can meet the requirement of various users.
8. Optional man-machine interface, with both charactron gun operation panel and color touch screen operation panel provided. 
9. All electronic devices are imported famous brand products, with reliable quality
