Module power supply industry in the Industrial Application(A)

With the continuous development of China’s electronic VGP-BPS9 industry, various industries for various industrial-grade product quality and technology requirements are constantly improving in order to achieve product quality, performance improvements, etc., etc., it is necessary for technical products innovation, so that technology innovation has become the most important issue of enterprise development. In the industrial control industry, most people with 24V bus power supply, its voltage range larger distance if the case may reach 30% or more of the change, if the product did not take some safety measures and protection circuits directly to the power control chip into the top-level power as a product, a result of the circuit in the voltage fluctuations and interference caused by the system, a great impact. The key study, first and foremost from the power supply part of the product (ie, power) to start, such as using the traditional linear power supply as the product of internal power supply, either from the volume of the output voltage accuracy, or conversion efficiency, are far from to meet the high reliability, high stability, to promote energy saving, safety first theme of the new century.

In view of this situation, we supply products to existing in-depth study found that the Sony vgp bps2c battery main question is: Product size big, start current, low voltage control, output and low accuracy problem. In response to this series of questions, MORNSUN’s continuous efforts to right the module power supply from the circuit design, manufacturing processes, to the detection line of innovative projects are launched 1W, 3W, 5W, 10W, etc. The wide-voltage modules of different power supply, the input voltage 5 (4.5 ~ 9) VDC, 12 (9 ~ 18) VDC, 24 (18 ~ 36) VDC, 48 (36 ~ 72) VDC four kinds of input voltage range up to 2:1, the conversion efficiency of up to 85 — 89%, and meet the industrial -40 ~ ~ +85 ℃ working conditions, long-term work at full load, suppress the electromagnetic interference and ground loop elimination, protect the system circuitry from the external network effects, while reducing power consumption, simplify the circuit . The specific application shown,
