Product classification:【Slkor】
Silicon Controlled Rectifier (SCR) is a high-power electrical component, also known as thyristor. It has the advantages of small volume, high efficiency and long service life. In the automatic control system, it can be used as a high-power driving device to control high-power equipment with low-power control. Widely used in AC and DC motor speed regulation system, power regulation system and servo system. Silicon controlled rectifier is divided into unidirectional silicon controlled rectifier and bidirectional silicon controlled rectifier. TRIAC is also called triac. Bidirectional thyristors are equivalent to two unidirectional thyristors in structure, and have the function of bidirectional conduction. Its on-off state is determined by the control pole g. Adding a positive pulse (or negative pulse) to the control electrode G can make it conduct in the forward direction (or reverse direction). The advantage of this device is that the control circuit is simple, and there is no reverse withstand voltage problem, which is especially suitable for AC contactless switches.
