利用微电子技术和电力电子技术对传统设备进行性能改造或节能改造时,若能在新设计的电路中注意到以下几点,将会更受用户欢迎。 1.凡只用到一对常开触点的继电器,尽可能选用固态继电器,特别是在通断频繁、灰尘多、振动大的场合。它较常规继电器可靠性高、寿命长、控制电流小,且费用比常规继电器低。 2.指示灯尽量选用发光二极管。目前市场上已有φ8、φ12高 The use of microelectronics and power electronics technology to transform the performance of traditional equipment or energy-saving transformation, if the newly designed circuit to note the following points, will be more user-friendly. 1. Where only a pair of normally open contacts of the relay, as far as possible the selection of solid state relays, especially in the off-frequent, dusty, vibrating occasions. It is more conventional relay reliability, long life, control current, and the cost is lower than conventional relays. 2. Indicators try to use light-emitting diodes. Currently on the market have φ8, φ12 high
