The automatic input device of spare power is modified by means of PLC new technology, which to realize the supervision and control to mother-connected circuit breaker in order to supply power consumption device safely and reliably. 介绍了天铁水电厂通过可编程序控制器新技术,改造备用电源自动投入装置,实现对母联断路器的监测与控制,以确保用电设备安全、可靠、优质的供电。
The small resistor can be layouted on the spare area of the chip, so the cost of the Integrate Circuit ( IC) will not increase. 该电阻在芯片上是利用闲置区域布线的,因此并不会增加集成电路的制造成本。
It describes spare time activities of digital circuit teaching and the effect on the interest of electronic activities and educate student to become qualified persons. 阐述了数字电路教学的校外课外开展活动的情况,在电子兴趣活动以及在培养学生成才方面的作用。
The power factor correction makes the system power factor and total harmonic distortion performance well. Controller can precisely control the LED current upon primary side regulated ( PSR). It spare optocoupler and secondary side regulated control circuit. 由于前置了功率因数调整器,使系统的功率因数和总谐波失真表现良好,而基于原边控制的控制器能够精确的控制LED电流,并且省去了光耦和二次测控电路,有效的减小了体积。
