Description:

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.

All these products adopt PWM high-frequency pulse width modulation technology, mature standardized production, strict 100% load-carrying aging, high and low voltage impact experiments and complete test records for development & production of LED driver through strictly quality control system and highly responsible attitude, thus have a good quality feedback during application.

Specifications:

Applications:

Widely used in LED Lighting, LED display, LED strips, LED advertisement screen, LED sign, LED night light, LED lamp house, LED decoration, LED wall light, LED street light , LED wall light, LED backlight, LED tube, offices , hospital , schools , factories , plants, shopping malls, supermarkets, kitchen, fair cabinet and so on.

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.
