--Welcome to LED switch power supply, please read this instruction manual thoroughly before using the LED switching power supply--

Product usage considerations:

1. Input voltage should be within the specified voltage range (input voltage: 220VAC).

2. Prohibited to be used in the high temperature environment, power port is the thermal vents, wind 50CM range, please do not place other objects, make sure that the power should have good thermal dissipation space environment.

3. Prohibited to install power supply in the presence of flammable materials (such as wood products, flammable plastic, etc), to stay away from petrol stations or where prohibited Fireworks.

4. Accurate calculation of load power, peak use, suggested user to use power supply based on power 80% load, do not overload.

5. Power supply have built-in short circuit protection function, when output short circuit, the power will automatically enter the status. Power off after 1 minute and then power on.

6. For safety, properly grounded, the output power cable must be ≥2.5mm²

Installation method:

1. Strictly in accordance with the position indicated by the output terminals of the power supply. It must be firm, check the output line and prohibited to be reversed (input "220VAC" main line, output "+" loaded for positive cathode, output "-" load for negative cathode).

2. Before power, check that the line voltage is compatible with the operating voltage with multimeter (voltage: 220VAC) recognized before it can be closed.

Selection of switching power supply

Switching power supply in input anti-interference performance, due to the characteristics of its own circuit structure (multistage series), the general input interference such as surge voltage is difficult to pass, compared with linear power supply, the output voltage stability of this technical index has a greater advantage, its output voltage stability can reach (0.5~1) %. As power electronic integrated device, switching power module should pay attention to the following points in the selection.

3.1 Selection of output current

Because of the high efficiency of switching power supply, generally can reach more than 80%, so in the selection of output current, user should accurately measure or calculate the maximum absorption current of electrical equipment, in order to make the selected switching power supply have a high performance ratio, usually output calculation formula-------Is=KIf

Is - rated output current of switching power supply;

If - the maximum absorption current of the electrical equipment;

K-margin coefficient, generally 1.5 ~ 1.8;

3.2 grounding

Switching power supply will produce more interference than linear power supply, and electrical equipment sensitive to common-mode interference should take grounding and shielding measures. According to EMC restrictions such as ICE1000, EN61000 and FCC, switching power supply should take EMC measures, so switching power supply should be equipped with EMC filter.

3.3 Protection circuit

Switching power supply in design must have over current, overheating, short circuit and other protection functions, so its design should be preferred to choose switching power supply module with protection functions , and its protection circuit technical parameters should be matched with the working characteristics of the electrical equipment, in order to avoid the damage to the electrical equipment or switching power supply.

The development trend of switching power supply technology

The development direction of switching power supply is high frequency, high reliability,low consumption,low noise,anti-interference and modularization. Because the high frequency is the key technology of switch power supply toward light, small and thin, therefore the major foreign switch power supply manufacturers are committed to synchronous development of new type high intelligent components, especially improving the wastage of the secondary rectifier device and the power ferrite (Mn zinc) on material increase scientific and technological innovation and to improve the high frequency and large magnetic flux density (BS) can obtain high magnetic.

The miniaturization of capacitors is also a key technology. The application of SMT technology makes switching power supply have made great progress. The components are arranged on both sides of the circuit board to ensure the light, small and thin of switching power supply. The high frequency of switching power supply is bound to innovate the traditional PWM switching technology. The soft switching technology of ZVS and ZCS has become the mainstream technology of switching power supply, and greatly improved the working efficiency of switching power supply. For the high reliability index, American switching power supply manufacturers reduce the stress of devices by reducing the running current, reducing the junction temperature and other measures, so that the reliability of products is greatly improved.

Modular is the general trend of the development of switching power supply. Modular power supply can be used to form distributed power supply system, which can be designed as N+1 redundant power supply system, and the capacity expansion of parallel mode can be realized. Against disadvantages such as running noise of switch power supply and the pursuit of high frequency will increase the noise, and using the partial resonant switching circuit technology, high frequency can be realized in theory, but also reduce the noise, but part of the practical application of the resonant conversion technology with technical problems still exist, therefore, it still needs to carry out a lot of work in this area to make the technology to practical application.

With the continuous innovation of power electronic technology, switching power supply industry has a broad development prospect. To speed up the development of switching power supply industry in China, we must go the road of technological innovation and the road of joint development of production, study and research with Chinese characteristics, so as to make contributions to the rapid development of our national economy.
