We are going to attend Guangzhou LED sign exhibition on March 3-6th,2018.Many new kinds of products will be showed at that time,including LED dimmable power supply,slim LED driver,etc.Welcome new and old friends to visit us at 11.3 hall C15 position.See you soon!

We are professional manufacturer of LED power supply for many years with own development and research team.One module sets triac,0-10v,pwm and resistance dimming types in one power supply.And it is very smoothly when dimming.

Now we have won good reputation in all over the world,as we are always dedicating to providing good quality and best service.The power supply raw materials are new,glass fiber PCB board,copper transformer and magnet ring,etc.The following picture will help you find a good product.

Now with technology developed and updated,more and more customers tend to like smaller size power supply with good stability.They are usually used in LED ultra thin light box.It likes bellow,only 30mm height.

Thank you all friends from all over the world for visiting and supporting Chengliang power supply exhibition.All new LED drivers are welcomed by all customers,new design,new image.

Dongguan Chengliang Electronic Technology Co.,Ltd is known as switching power supply manufacturer with certain scale and good reputation in world.Not because of its advertising,but its standard process and strict quality control,and also its perfect service system. 1.Workshop 2.Assembly 3.Automatic welding 4.Hand inspection welding 5.Debugging 6.Labelling 7.Burn-in test 8.Packing So strict production process,what are you waiting for?If you have interest,call or email me immediately.We are looking for sincere partners.

By connecting the smart home switch with the intelligent control, all the light switches can be controlled in the living room, eliminating the need to move around. You can also set the scene memory mode to control the light switch, brightness, etc., dimming brightness range 0-100, dimming process does not flicker and light smooth, free to control the lighting pattern of the living room, dining room, study room, aisle. Intelligent lighting system with dimming power supply can realize manual control, one-touch control of APP, one-touch control of APP, network control, color brightness adjustment and soft start function. Stable and reliable performance, a number of protection features; increase the lamp life, can be used with confidence, reducing the maintenance cost of the dimming power supply and failure rate.

As the heart of electronic equipment,switching power supply plays a crucial role in the safe and reliable operation of electronic equipment.So how to use LED driver is the most important. 1.Before using the power supply, determine whether the input and output voltage specifications match the nominal value of the power supply used. 2.Before power on, check the input and output leads are connected correctly to avoid damage to the user equipment. 3.Check whether the installation is firm, whether the mounting screws are in contact with the power board components, and measure the insulation resistance of the housing and the input and output to avoid electric shock. 4.To ensure the safety of use and reduce the interference, please ensure that the grounding terminal is reliably grounded. 5.Frequent turning on or off the power supply, as well as the working environment and degree of loading, will all affect its life.

At present, LED lighting fixtures are used in a wide range of applications. It is divided according to space,airport lighting, indoor lighting, outdoor lighting, building lighting, and so on, the more widely used lamps and lanterns are downlights, spotlights, and panel lights. The LED dimmable power supply is now available in many lighting fixtures. It has been widely used. In the future, this kind of power supply will be the advocacy and guidance of green lighting in the society. Its development will bring technical support to the LED lighting industry.It can also provide home users with professional use of the most reliable experience, so the prospects for the development of this power is very impressive.

The P360W12V 3D printer power supply produced by our company has stable performance, sufficient power, high efficiency, no flash frequency, low temperature rise, small ripple, more than 87% power efficiency, low operating temperature, good heat dissipation performance, low noise and soft Start current, reduce AC input current impact, comply with safety EMC requirements.

Triac 0-10V LED dimmable power supply is compatible both leading edge and trailing edge, it can work with many systems like Lutron.Dimming range 0-100%. Natural air cooling can work at low temperature -30 °C high temperature +60 °C. Output short circuit protection, overload protection and overheat protection; 50,000 hours long life design. Product 2 years Warranty. In line with the world lighting equipment safety standards, intelligent adjustment and maintenance of current, suitable for different thyristor dimmers, in the full dimming range to ensure that the dimming is smooth, stable, no flicker. Suitable for LED home lighting and commercial lighting Application.

As a professional manufacturer of LED power supply,we should take an important factor into consideration,that is the efficiency.It will produce much heat when converting AC to DC,if improve the efficiency,try our best to reduce the power loss,and make it effective energy to load LED strip and module.The higher the efficiency,the more the loading,and the longer the life.

2017 Guangzhou LED Signs and Lighting Exhibition.Thanks all new and old customers from all over the world for visiting our hall.Many kinds of LED power supply,LED driver,LED transformer,SMPS for your choice.
