Technical parameters: ABB 5SHX1960LO004 Thyristor electronic components DC motor speed control system
5SHK19501204 thyristor tlicon ControlldBRettie SCR is a high-power electrical component, also known as the county gate tube. It has the advantages of small size, high efficiency and long life. In the automatic control system, it can be used as a high-power drive device to realize the control of large rate with small power control, it has been widely used in the AC direct washing motor speed control system, power regulation system and servo system, 5SHX186004 controllable one-way thyristor and bidirectional thyristor two. Bidirectional thyristor is also called three-terminal bidirectional thyristor, referred to as THIAC. Bidirectional thyristor in structure. On the equivalent of two one-way thyristor reverse injection This thyristor has a double pilot pass function. Its on-off state is determined by the control pole G. Add a positive pulse (or a negative pulse) to the control pole G to make it pass forward and reverse. The advantage of this device is that the control electric skeleton is simple and there is no reverse voltage problem, and the chemical agent is suitable for AC contactless switch use. 5SHK19504 We use a one-way gate answer, that is, people often say ordinary thyristor, it is composed of four houses of semiconductor materials, there are three E PN junction, Externally, there are three electrodes [FIG. 2a] 1 The electrode led by the first layer of P-type semiconducting is called E-pole 4 The electrode led by the third series P-type semiconducting forest: the electrode bowing out of the control pole G section is called pole X. 5SHK19604 From the most thyristor electrical symbol figure 2b) can be seen), it and diode - like is a single direction conductive device, the key is more than a control pole G, which makes it have completely different working characteristics with the diode
