"Walking on the Shrimp Mountain, Building Good Words" Rural Revitalization Hiking Survey

Founded in September 2002, Zhuhai Dapeng Electronic Technology Co., Ltd. is a national high-tech enterprise specializing in the research and development of optoelectronic packaging device products.

The company has focused on packaging device products for 21 years, and has now completed a complete set of automated production lines for optocouplers. Its device packaging products have formed a series of optocouplers (817 series, 814 series, 816 series, 354 series, 357 series), infrared photoelectric switches, and infrared receiver heads. Its products have obtained UL, VDE, and CQC product safety certification

What role does an optical coupler play in a switching power supply

Switching power supply optocoupler is mainly used to isolate, provide feedback signal and switch. In a switching power supply circuit, the optocoupler is supplied by the secondary voltage of a high-frequency transformer. When the output voltage is lower than the voltage of the regulator, it will be sent to the signal optocoupler to open and increase the duty ratio to increase the output voltage; Otherwise, it will be turned off to reduce the duty ratio of the photocoupler to reduce the output voltage. High frequency transformer secondary load overload or switching loop failure, there is no fault optical coupling power supply, optical coupling control switch circuit does not vibrate, protection switch tube does not breakdown, no burn.

Understand the application and classification of relays

A relay is a device that uses the effect of current to close or disconnect a circuit for automatic protection and control. In most cases, a relay is an electromagnet whose armature can close or break one or more contact points. When there is a current through the winding of the electromagnet, the armature is attracted by the electromagnet, thus changing the state of the contact. The main role of relay is to detect, transfer, transform or process signals. The circuit current it breaks is usually small, that is, it is generally used in the control circuit (and the "main circuit" contrast).

What is the difference between linear and ordinary photocouplings in terms of current transfer ratio CTR

Photoelectric coupler is a kind of electrical - optical - electrical conversion device which transmits electrical signal by optical medium. It consists of two parts: a light source and a light receiver. The light source and the light receiver are assembled in the same closed shell and separated from each other by a transparent insulator. The pin of the light source is the input end, the pin of the light receiver is the output end, the common light source is the light emitting diode, the light receiver is the photosensitive diode, photosensitive transistor and so on.

Type of optical coupler, how to choose and replace

Optical couplers transmit electrical signals in the medium of light. It has a good isolation effect on the input and output electrical signals, so it is widely used in various circuits. At present, it has become one of the most diverse and widely used photoelectric devices. Photoelectric coupler generally consists of three parts: light emission, light reception and signal amplification. It has strong anti-interference ability, stable operation, no contact, long service life, high transmission efficiency.
