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

7. 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).

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

9. Power firm installed vertically (vertically in a place easy to wire the power supply, cover to cover, to be water proof)

The overview of Switching power supply

Switching power supply is a device which use modern power electronics technology to control time ratio of switching tube open and off and maintain a stable output voltage of power supply, switching power supply is generally composed of IC and MOSFET which is controlled through pulse width modulation (PWM) compared with linear power. The cost of switching power supply increases with the increase of output power, but the growth rate is different. Linear power cost is higher than switching power supply at a certain output power point, which is called cost reversal point. With the development and innovation of power electronics technology and switching power supply technology constantly innovating, this cost reversal point is increasingly moving to low output power end, which provides a broad development space for switching power supply.

Switching power high-frequency is the direction of its development, high-frequency will make switching power miniaturization and make switching power into a wider range of applications, especially in the field of high-tech applications, promoting high-tech products miniaturization and portability. In addition, the development and application of switching power supply are of great significance in energy saving, resource saving and environmental protection.

The main power electronic devices used in switching power supply are diode, IGBT and MOSFET.

SCR has a small number of applications in switching power supply inputting rectifier circuit and soft start circuit, GTR is difficult to drive with low switching frequency and gradually replaced by IGBT and MOSFET.

Three conditions of switching power supply

1. Switching: power electronic devices work in the switching state rather than linear state

2. High frequency: power electronic devices work at high frequency rather than low frequency close to power frequency

3. DC: switching power supply output is DC rather than AC
