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

First , Principle of product overview:

A stable DC voltage.

Second, Product features:

1. Small size, light weight;

2. Wide operating voltage range: input voltage 110-240V work properly;

3. Security, high reliability;

4. Performance: high power switching power supply have 5-10-second delay test circuit design, very well put an end to be output high-voltage switching power supply powers on an instant high current so as to protect the load (especially LED light source, reduction of mutations of light caused by the maximum output voltage );

5. Protection: short circuit, over current, overheating protection;

6. Easy installation: this product is designed to be water-proof (outdoor) and not waterproof (indoor) in two ways. Waterproof power with high strength, rust-proof metal enclosure structure design for hanging, suspension setup, reducing input and output connection cables;

7. When the load is too large, power protection, intermittent breaking exception occurs, user should reduce the load.

Third, Usage instruction

1. Under normal conditions of use, it will be one year warranty based on date of flag, product fails during the warranty period, and test by the company are quality problems , which means free warranty.

2. The following conditions are not within the scope of warranty

(1) Not follow the specification required and damaged.

(2) Users remove internal components which caused damaged unit.

(3) Water deep into the box;

(4) The serious damage or deformation of shape;

(5) The body dates being erased or altered;

(6) Terminal block burned;

3. Maximum responsibility for defectives products is a replacement of the same model and the same number of products

Difference between CV & CC

Constant voltage power supply is power circuit that controls output voltage at a constant level. It always provides a constant voltage regardless of the load and is widely used as power supply for electronic circuits.

Constant voltage power supply is power circuit that controls output voltage at a constant level. It always provides a constant voltage regardless of the load and is widely used as power supply for electronic circuits.

Constant current power supply is a power supply circuit that controls the output current at a constant level. A constant current power supply is used to power LED lighting and charge rechargeable batteries.

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.
