SBH series high-voltage inverter is a new generation of high-performance, multi-functional unit series high-voltage inverter independently developed by Hope Senlan Technology Co., Ltd., with high power factor, high reliability, high efficiency, low harmonic content, low loss, easy maintenance, small footprint and other characteristics, is a high-voltage direct input, inverter high-voltage direct output of "high-high" high-voltage inverter, suitable for general three-phase high-voltage induction asynchronous motor, can be widely used in metallurgy, electric power, machinery, papermaking, building materials, chemical, petroleum, pharmaceutical, mining and other fields.
Performance characteristics:
High power-saving rate: variable speed drive of square torque load such as fan and water pump can save power with large fluctuations;
High efficiency: the inverter efficiency > 98.5%, and the efficiency of the whole machine > 97%;
High power factor: input power factor > 0.95, no power factor compensation equipment required;
High reliability and long life: the planned life is 20 years, the uniform trouble-free working time is > 100,000 hours, and the uniform correction time MTTR is < 10 minutes;
No output filter required: the output voltage harmonic is <3%, no output filter is required, suitable for new or existing general high voltage motors;
Motor control mode: no PG V/F control, with PG V/F control.
The SB70 series four-quadrant vector control inverter can be used for potential loads or large inertial loads with sharp deceleration, and the regenerative energy generated during the braking process is fed back to the power grid to complete the two-way flow of energy. The inverter does not need to install a braking unit and braking resistor, and the regenerative energy is no longer consumed in the form of thermal energy, which brings greater energy saving, and the deceleration is more stable and reliable. The front end of Sunland's four-quadrant inverter selects IGBT PWM rectification technology, optimizes the SVPWM control algorithm, and the power factor is close to 1, which reduces harmonic pollution to the power grid and makes the inverter truly a "green inverter".

How far apart is the motor from the inverter - Senlan inverter
The supplier of the supporting equipment of the inverter reminds you that the voltage waveform output by the inverter is similar to a sine wave, but not a real sine wave. Its waveform contains a large number of harmonic components, especially the higher harmonics will increase the output current of the inverter, causing the motor winding to heat up, and produce oscillation.
