 . After one second, the voltage is reduced to 20 to 25 VDC for as long as AC power is applied. When AC power is removed, the DC voltage is removed from the contactor coil and the contactor drops out. The cycle is repeated when AC power is reapplied to the CEM. The purpose is to provide the high coil voltage for a long enough period of time necessary to pick up the contactor (1 second) and then transition to a much lower coil voltage to economically maintain the contactor in a sealed closed condition. This reduction in voltage reduces power consumption and greatly reduces temperature rises in the coil. MX MX MX M Supp Start-Stop Control 2 4 3 1 CEM Contactor Economizing Module G21 GE Limitamp® Medium Voltage Motor Control Components G Description The power-dip ride-through feature is available for critical process applications where forced motor shutdowns are very disruptive and where power system outages are expected to last less than 20 cycles (333 milliseconds). If a loss of power occurs while the main contactor M is closed (see diagram) relays UV and MX transition to the deenergized state. The normally-closed contact of UV and the normally-open contact of MX in the coil circuit overlap as they change state, thus avoiding an interruption of the decaying coil current. 一秒钟后，只要使用交流电源，电压就会降至20至25 VDC。当交流电源断开时，直流电压从接触器线圈上断开，接触器断开。当CEM重新接通交流电源时，循环重复。其目的是提供足够长时间的高线圈电压，以拾取接触器（1秒），然后转换到低得多的线圈电压，从而经济地将接触器保持在密封闭合状态。电压的降低降低了功耗，并大大降低了线圈中的温升。MX MX MX M Supp启停控制2 4 3 1 CEM接触器节电模块G21 GE Limitamp®中压电机控制组件G说明功率下降穿越功能适用于强制电机停机非常具有破坏性且电力系统停机预计持续时间少于20个周期（333毫秒）的关键工艺应用。如果在主接触器M闭合时发生断电（见图），则继电器UV和MX转换到断电状态。UV的常闭触点和线圈电路中MX的常开触点在改变状态时重叠，从而避免了衰减线圈电流的中断。
