Intelligent building
Intelligent home controllers and home smart devices are developing into miniaturization, so they need to work reliably in limited space and achieve more functions. For example, the curtain controller has remote control and panel display.
Power supply:
Through 220V through the AC/DC power supply module, CEP converts into a stable 5V or 12V voltage source for MCU, relays and other loads.
Programme characteristics:
The traditional scheme 1: The power of the city is changed into low-voltage alternating current through the power frequency Transformer, and then the rectifier filter voltage stabilizing circuit is processed to obtain a stable voltage. The disadvantages are large size, low efficiency, and low reliability.
Traditional plan 2: Adopt the latest switch power supply, circuit design, will be the whole Dianlubu on the controller circuit board, shortcomings: 1, because the design of the switch power supply is very professional requirements, the safe distance in the circuit, The thermal design and EMC are all required, which makes the design of the circuit board occupy a lot of space, squeezing the space of other devices of the controller, which will inevitably affect the performance and volume of the controller. 2, the aging of the power supply is not complete, the power supply is only overloaded aging, exposing some potential bad factors, because the controller's responsibility is generally very light, so it is possible to flow bad products into the client.
The characteristics and advantages of the existing scheme, the AC/DC module power supply is a pressure control module implemented by special processes, has a good protection function and high efficiency, advantages: 1, the volume is at least and more than half the volume of the design control panel 2, due to the module. The body adopts rubber shell design, Safety is better 3. Since the module design has only 4 input and output lines for the circuit design, it saves more cloth board space 4 for the control board, and the reliable cost of the module power supply is higher than the aforementioned 5, and the overall cost of production is lower.
Recommended Product Series:
The miniaturized needle series has important applications in many fields such as smart home, lighting, and electrical appliances.
(3 ~ 20W)
The miniaturized series customers provide an ultra-small volume modular power supply with a full series thickness of only 1.5 CM, which is widely used. It has the characteristics of extremely low empty load loss, isolation and pressure up to 3KV. Product safety and reliability, EMC performance is good, EMC and safety specifications meet the relevant standards such as IEC / EN61000-4, CISPR 22/EN 55022, UL60950/EN60950 / EN60601, etc.. This series of products are widely used in smart homes, high-end lighting, medical, industrial control, office and civilian industries. For example, application circuits must be referred to when applied to environments where electromagnetic compatibility is relatively poor.
