What is LPI Certification Under? What is LPS? What is LPS Certification

LPI (Linux Professional Institute) is a non-profit organization based on and serving the international Linux community, headquartered in Toronto, Canada. LPI hopes to bring together companies and professionals who are willing to invest in and realize the Linux business into an active and responsible community to promote the continuous improvement of Linux technology around the world. LPI is constantly looking to improve Linux technology and make it widely available by providing services and setting standards.

The LPI organization has become a world-recognized internationally renowned organization that advocates and assists the professional application of Linux, free software and open source**, and has established a wide range of cooperation alliances around the world.

LPI's industry-standard certification has been implemented all over the world, the certification is supported in multiple languages around the world, and the certificate obtained represents world-class Linux skills, which is globally recognized and has become the reference certificate for the skills of most of the world's famous IT companies to recruit senior employees.

Introduction to the Ministry of Industry and Information Technology of the People's Republic of China.

The Ministry of Industry and Information Technology of the People's Republic of China (MIIT: Ministry of Industry and Information Technology), formerly known as the Ministry of Information Industry, was established according to the institutional reform plan of the 11th National People's Congress. The IT industry qualification certification issued by the Electronic Education and Examination Center of the Ministry of Industry and Information Technology of the People's Republic of China has the highest authority in China.

LPS is not a certification, but a requirement. LPS (Limited Power Supply) requirements are specified in the IEC 60950 1 standard. These requirements can be used to define power supplies with relatively low voltages, currents, and capacitances.

The advantage that LPS power supplies bring to customers is that system installers only need to comply with relatively lenient requirements when cabling and physically installing loads powered by LPS-certified power supplies.

It is generally accepted in the industry that power supplies that can be used as qualified LPS will not cause electric shock or fire because they have a limit on the output current and voltage they can deliver to the load. The following summarizes the specifications of power supplies that are certified as inherently limited power delivery LPS (VA=Volts*amps, VOC=Open-Circuit Output Voltage (No Load)):

1. DC voltage less than or equal to 30VDC or basic sinusoidal AC voltage less than or equal to 30VACRMS.

2. The maximum short-circuit current is 8A

3. The maximum VA is 100

4. The maximum marked output power rating is 5A*VOC

5. The maximum marked output current is rated at 5A

6. The ripple is greater than 10% of the peak DC voltage and non-sinusoidal AC voltage.

7. The maximum voltage peak is.

8. The maximum short-circuit current is 8A

9. The maximum VA is 100

10. The maximum marked output power rating is 5A*VOC11, and the maximum marked output current rating is 5A

12. DC voltage greater than 30VDC and less than or equal to 60VDC.

13. The maximum short-circuit current is 150VA VOC

14. The maximum VA is 100

15. The maximum marked output power rating is 100VA

16. The maximum marked output current is rated at 100VA VOC

The full name of LPS in English is Limited Power Supply. Chinese means that the output power of the power supply is limited.

LPS is not a certification, but a non-mandatory requirement in IEC 60950-1 clause power supplies.

LPS is a substance that activates the body's immune cells, and LPS is found in fertile soil and has been present in the human body since ancient times along with vegetables, fruits, and grains.

Due to the poor soil due to the overuse of pesticides and fertilizers, LPS gradually disappeared from the table.

Studies in countries around the world and the 2011 Nobel Prize have confirmed that various metabolic problems and immune imbalances such as cold-related diseases, including colds, highs, allergies, asthma, atopic dermatitis, insomnia, anxiety, etc., are related to the lack of LPS in the human body.

Japanese scientists found in a study that the concentration of LPS in normal people is at least 40mg per day, and sub-healthy people need to double the dose to improve better.

The LPI (Linux Professional Institute) is an internationally renowned organization that advocates and assists in the professional application of open source**, Linux, and free software.

LPI certification is a certification system based on the needs of jobs in the Linux environment to meet the needs of the whole society for qualified Linux technical talents and reduce the cost and risk of Linux talent recruitment.

The full name in English is Limited Power Supply. Chinese means that the output power of the power supply is limited.

Not a certification, but a non-mandatory requirement in IEC 60950-1 clause for power supplies.

The LPI certification exam can be taken in almost any country and can be scheduled according to your own schedule. Follow these five steps to understand the exam process for LPI certification:

Step 1: Register.

Regardless of how or where you take the LPI certification exam, you must register online to obtain your LPI ID number. If you are unable to complete this step, it will most likely affect the schedule of your LPI certification exam. In addition to this, you must also provide your LPI ID number to the test center when you register for the LPI certification exam.

Registration is done for you by the test center.

Step 2: Fill out the exam application form & pay the exam fee.

The LPIC (Linux Professional Institute Certification) offers multiple levels of certification exams, please indicate the items and levels of the LPI certification exam you are taking...and complete the exam application form as required. and pay the corresponding examination fee.

Step 3: Schedule to take the exam.

After the candidate pays the test fee and fills in the detailed test application form, the authorized center will make an appointment with the LPI test center for the nearest test time, and the test taker will be arranged for the test as soon as possible.
