high-voltage frequency converter

الوصف

PowerSmart series high-voltage large power frequency converter is a voltage-source-type high frequency converter, and it is a multilevel topological structure with multipulse rectification, multiple PWM, and overlapping by units in series. It has the features of high power factor and low harmonic wave pollution, and its and output current waveform is similar to that of sinusoid. PowerSmart series highvoltage large-power frequency converter is a high-efficient, energy-saving product developed by applying modern electric and electronic technology, electric traction technology, computer control technology, etc. It applies advanced dividing technology, optimized series overlapping technology, special single-phase bridge inversion technology, best optical fiber conduction technology, perfect overvoltage protection technology, waveform continuous transformation technology, long-distance communication control technology, etc. National patents for most of these technologies have been applied for. 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 and output harmonic waves, which little affects the power supply system and the motor. 4. High 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. e-mail:xxxxx
