CMC-MX soft starter is suitable for starting and protecting general squirrel-cage AC asynchronous motors. Adapted motor power from 7.5kW to 280kW. It can smoothly start/stop the motor without steps, avoid mechanical and electrical shocks caused by traditional methods such as direct start, star/delta start, auto-coupling step-down start, etc.
XiChi XPQ Active Filters are used for Harmonic Reduction in Haier IOT Center. The active power harmonic filter (APF/AHF) suppresses the harmonic current on the load side to a great extent, and the overall harmonic filtering effect is obvious.
In the process of starting the motor, the soft starter gradually changes the conduction angle of the thyristor, so that the starting current of the motor rises smoothly from zero to the maximum value. The whole process runs smoothly, the reliability of the motor power supply is high, the impact torque on the mechanical load is reduced, the impact on the motor itself is small, and the service life of the motor and the entire equipment is prolonged.
The harmonic control technology of active filter equipment is one of the effective means to improve the quality of power supply. After the popularization and application of APF in the power supply system of hospital buildings, the generated harmonics can be controlled within the minimum range. Realize scientific and rational use of electricity, restrain grid pollution, improve power quality, ensure the safety of medical equipment, and bring huge economic and social benefits to users.
