| How to energy-saving soft starter? |
| Motor belongs to the inductive load, current hysteresis and voltage, most appliances are such.
In order to improve the power factor to be used to compensate capacitive load, and capacitance compensation or synchronous motor. Reduce the magnetizing current motor can improve the power factor (HPS2 energy-saving function, reduce the voltage, the excitation current at light load is reduced, so that increasing COS 13). Energy-saving operation mode: light load reduced voltage reduces the excitation current, the motor current is divided into active component and wattless component (excitation component) to improve COS ¡Ó. | | | author: Published at: 2013/4/28 16:12:40 |  |
