LVLP series Linear Power Supplies are DC Power Supplies that achieve AC/DC conversion through power frequency transformers and transistor loop control. Compared with switching DC power supplies, linear mode power supplies have higher stability, higher accuracy, and lower output ripple. And the most important, because of the use of the power frequency AC/DC conversion principle, the linear power supply does not have high-frequency radiation interference, and is especially suitable for use in places with restrictions on EMC and EMI.
The LVLP series linear AC - DC power supplies have a wide range of output specifications, the output power ranges from 1KW to 400KW, and the output voltage can reach up to 800VDC, and accept customization.

As of April 2008, the global installed capacity of wind power exceeded 100 million kilowatts. China has become the fourth country in the world with wind power installed capacity exceeding 10 million kilowatts. In 2008, China's solar thermal utilization is expected to increase by about 30%. New capacity and cumulative installed capacity lead the world; a large number of industry leaders have emerged and broadened their manufacturing capacity distribution in China. At a time when global concerns are about the prospects for climate negotiations, breakthroughs in new and renewable energy technologies are expected to provide new ideas and hopes for the world to address climate change.
LED street lights can save about 40% energy
According to the Beijing Street Light Management Center, after a one-and-a-half-year trial, Beijing pilot LED street lights have obtained preliminary data. Under the same illumination, LED street lights can save about 40% energy.
Reducing lighting power is an important way to save energy. For this reason, Beijing has successively piloted LED street lights in Zuo'anmen and Biancai Hutong. According to a person from the Beijing Street Light Management Center, through a one-and-a-half-year pilot, LEDs consume one-eighth of the incandescent bulbs and one-half of the fluorescent tubes in the same lighting effect. Overall, LED street lights can save about 40% energy. From the environmental point of view, LED lamps do not contain harmful elements such as mercury and sodium, and will not pollute the environment. They are products that are more in line with green lighting and have good social effects.
It is understood that street lamps have passed three stages, such as incandescent lamps, mercury lamps, and sodium lamps. At present, the fourth-generation lamps are still inconclusive. The person also admitted that, based on the current price of lamps, the total investment cost and operating cost of LED street lamps is much higher than that of high-pressure sodium lamps. In addition, since the LED has no light distribution, the illumination uniformity and the like need to be further improved.
4 trillion funds for ecological environment investment 350 billion
According to the National Development and Reform Commission, the investment in the ecological environment is 350 billion yuan in the specific plan of 4 trillion yuan investment. In actual work, it is necessary to adopt a series of measures such as planning guidance, industrial policy, land policy, environmental protection policy, energy conservation policy and project review to make local investment conform to the direction determined by the central government, to adjust the structure, transform the development mode, and solve the people's livelihood. The problem is to solve the ecological environment problem.
In 2008, the central government took out 100 billion yuan to save the market in advance, and arranged 12 billion yuan for accelerating energy conservation, emission reduction and ecological construction projects.

The whole series DC linear power supply adopts industrial-grade metal chassis, pure copper AC/DC varnished transformer, high-reliability multi-transistor filter loop, ensuring the power supplies can run for a long time at full load with high stability, high accuracy, and ultra-low ripple electronic characteristics, equipped with a complete protection circuit, which can better ensure the reliability of the linear power supply itself and the safety of the customer's load.
The output voltage and current can be adjusted by the 10-turn potentiometer with scale and lock on the front, equipped with 4 1/2-digit high-resolution LED meters for output value reading, and RS communication interface can also be added for remote control and monitoring of linear power supplies.
This series of linear power supplies are mainly used for aging and testing of components such as capacitors, relays, and resistors, and can also be used for experimental testing of electronic components such as thermistors and motors. At present, many well-known capacitor manufacturers, resistor factories and other electronic component production units and scientific colleges and universities and other research and development units use this series of power supplies, and they have all been highly praised.
