Power is not only the key to modern industry and daily life, but also the key driving force for the country to achieve economic growth and improve people's living standards. At present, all walks of life are vigorously promoting the progress of localization, and the power industry does its utmost: all equipment companies are required to match the whole network and achieve national industrialization; At the same time, after years of market verification, domestic materials have gradually come up to the international level in terms of reliability, and even have advantages.

For power supply, localization is mainly reflected in the enterprise nature, production, materials and other aspects of components. Some power supply manufacturers represented by Jin Shengyang have broken the technological monopoly by relying on their production and research strength, and have successively released 100% domestic product lines of components that have passed the agency certification.

1、 Recommended Localized Power Supply for Power Industry

Based on the market demand of the power industry, Jin Shengyang developed components and parts 100% localization LO-E-GH series of products not only meet the performance indicators and reliability required by the industry, but also ensure stable and reliable delivery time and cost.

Advantage 1: Excellent EMC performance

The application environment of the power industry is complex, and there are many potential electromagnetic interferences. The power supply is required to meet high EMC performance.

Jin Shengyang aims at the pain points of the industry, LO-E-GH power special series The dithering design is adopted, which has lower EMI interference, larger margin, simpler peripheral circuit, and more than double the margin of similar products, EMS meets the requirements of power level IV standard ； At the same time, the surge immunity is up to 4KV, with strong anti-interference ability, which is suitable for applications in harsh environments.  

Advantage 2: Ultra wide input voltage

Power equipment is usually used in outdoor harsh environment, and the power grid fluctuates greatly. In view of the problem that the front end may have voltage fluctuations, which may lead to power failure, the power supply is required to have an ultra wide input voltage.

Jin Shengyang LO-E-GH power special series , input voltage can be as wide as: 85-305VAC It can also work normally under the condition of transient high voltage, meeting the AC and DC adaption of power protection device.

Advantage 3: High reliability and high applicability

Electric equipment is applied in outdoor open environment, with high replacement/maintenance costs, and high reliability of equipment is required.

In order to reduce the operation and maintenance cost of power equipment, Jin Shengyang focused on the reliability of power supply in the design:

● High degree of automation: automatic plug-in process design;

●  Simple design: reduce redundant design and simplify circuit structure without sacrificing performance.

●  At the same time, it has three prevention processes: moisture-proof, salt fog proof, mold proof, and more reliable products!

Jin Shengyang National production and chemical LO-E-GH series The product has excellent performance and meets the mainstream demand of the industry. The following figure shows the comparison of the detailed parameters with other brand products.

2、 Typical application scheme of relay protection system

The relay protection system has many external interfaces, so it is easy to introduce interference. There are generally two ways to deal with interference: one is to filter the circuit, and the other is to isolate each power supply.

It can be seen from the whole power supply scheme above that each functional module has been isolated accordingly, and the mutual interference between the functional modules in the working process has been effectively handled.
