What are the advantages of metal button switch in use? Here we will give you a detailed introduction.
Compared with linear power supply, metal button switch has lower output power point, which is called cost turning point. With the development and innovation of power electronics skills, the metal button switch skills are also constantly innovative. This turning point of cost is increasingly moving to the low output power terminal, which provides a wide expansion space for the metal button switch. Here's a brief introduction to some of its features.
Metal button switches have more disturbances than linear power supply. Grounding and shielding methods should be adopted for common mode disturbance sensitive power equipment. According to EMC constraints such as ICE1000, EN61000 and FCC, metal button switches adopt EMC methods. Therefore, metal button switches should usually have EMC filters. If the HA series metal button switches with Lidworf skill connect their FG terminals to the earth or to the user's case, the above EMC requests can be satisfied.
2. Classification of metal button switches:
In the field of metal button switching skills, we are developing power electronic equipment and frequency conversion skills. Both of them promote each other and push metal button switching in the direction of light, small, thin, low noise, high reliability and anti-disturbance in order to exceed the two-digit growth rate every year. Metal button switches can be divided into AC/DC and DC/DC two categories. DC/DC converters have been modularized, and planning skills and production skills have been sophisticated and standardized at home and abroad, and have been recognized by users. However, AC/DC modularization, because of its own characteristics, encounters more confusing skills and skills production problems in the process of modularization. The structure and characteristics of two kinds of metal button switches are discussed below.
3. Maintenance Circuit
It is necessary for metal button switch to have maintenance functions such as overcurrent, overheat and short circuit in planning. Therefore, the metal button switch module with complete maintenance function should be preferred in planning, and the technical parameters of its maintenance circuit should be matched with the operation characteristics of the electrical equipment in order to prevent damage to the electrical equipment or metal button switch.
