而软起动器内置的过载保护功能是根据I2t算法用电子装置来完成的。它可根据起动负荷的轻重即起动时间的长短不同来选择不同的脱扣特性曲线以避免在起动过程中误跳。由于它的过载保护是可编程的，从而为用户提供了更大的灵活性。并且选用带内置过载保护功能的软起动器可以省去热继电器，使控制柜内布线更简单，迅速。4）参数测试功能可通过按键在显示窗口选择显示电机的运行参数如三相电压值、三相电流值、功率因数、运行时间等，而不需增加任何仪表。此功能可使用户很方便的查询电机在运行过程中的各种参数。5）消防水泵定期自动试机由于消防水泵属消防应急设施，平常时长期处于不使用状态，容易出现泵卡死的现象。一旦火灾发生时如果无法正常运转。

如果VS的控制极没有输入触发脉冲Ug，VS仍然不能导通，只有在U2处于正半周，在控制极外加触发脉冲Ug时，晶闸管被触发导通。画出它的波形（c）及（d），只有在触发脉冲Ug到来时，负载RL上才有电压UL输出。Ug到来得早，晶闸管导通的时间就早；Ug到来得晚，晶闸管导通的时间就晚。通过改变控制极上触发脉冲Ug到来的时间，就可以调节负载上输出电压的平均值UL。在电工技术中，常把交流电的半个周期定为180°，称为电角度。这样，在U2的每个正半周，从零值开始到触发脉冲到来瞬间所经历的电角度称为控制角α；在每个正半周内晶闸管导通的电角度叫导通角θ。很明显，α和θ都是用来表示晶闸管在承受正向电压的半个周期的导通或阻断范围的。

开通Q1并自动再次连通负载。上述过程会一直周期性重复下去，除非移去多余负载或将MAX668关闭使其停止工作。因此MAX810L和开关Q1一起构成了一个固态开关（电子丝）。丝丝MAX810L（微功耗器件）具有非平衡推挽输出级。当对外输出电流时，它等效于一个6kΩ电阻；当从外汲取电流时，它等效于一个125Ω的电阻。当导通或关断Q1时，由于MAX810L的电阻阻止了Q1的密勒电容和栅源电容快速充放电，因此使开关瞬态过程得以减慢。假定Q1总的等效电容为5000pF时，则MAX810汲取电流时（等效于125Ω电阻）大电流三极管的RC电路的时间常数约为0.6μs。整个导通过程电压瞬态响应时间大约为10RC=6μs。
