Hangzhou Zhongheng Power Energy Co.,Ltd

Professional LED Driver Manufacture

We provide OEM services to valuable clients, advise us your requirements, we will customize a suitable LED Driver for you.

• This is our standard production process of led driver, the process which is in black frame is very very important, it can indicate the quality control ability of a factory, there will be more introduction about be important process in the next.

• The brand of this wave soldering is SUNEAST, which is a world famous brand from Japan. It is fully computer control, the speed and temperature of each product can be set up in the computer. Why do we choose a 3 stage preheating wave soldering, because it is good for our LED Driver. As we all know, the heating can affect and components and PCBs, if the temperature rises up step by step, it can eliminate the stress, especially for the Resistance, Ceramic capacitor, PCB board, which can ensure the quality of LED Drivers.

• This is the ICT test station, In circuit test, it is used to test whether the component is ok or not, such as the resistance, capacitance, Voltage drop, Polarity. Every product has a set of mould, the cost of each test mould is about 1000US$, many factories don’t have this kind of ability, so they only test several products, not all of them, but we do. You can’t make sure that the components are still ok after wave soldering, so this kind of test equipment really helps a lot. cii-font-family:Calibri;mso-hansi-font-family: Calibri’>stress, especially for the Resistance, Ceramic capacitor, PCB board, which can ensure the quality of LED Drivers.

• Now we come to the ATS test station, the machine can test the integrity of the products automatically; the test spec is output voltage, PF value, efficiency, Ripple and Noise, the test results are displayed on the screen. The brand of this machine is Chroma, the best brand of ATE equipment. There are also other 3 sets Tektronix brand ATS equipment, it takes 30 seconds to test 1 piece power supply, meanwhile, it can save a lots of time, and short the lead time, I am sure that many customers hope that there is no lead time exists, they can get the products immediately after they pay, that’s what we are fighting for.

• This is a burn-in room in our company, constant temperature, 45 degree Celsius, and the humidity is 25%. If one of the products broke, then the sensor will give an alarm. And the load is electronic type, not resistance type, this kind of load is very stable, to some extent, it can extend the life of the LED Driver. The LED Driver will be burned here two times, 4 hours(half load) for the first time and 8 hours(full load) for the second time.

• The material of the glue affect the quality of the LED Driver directly, it has waterproof, inflaming retarding and heat dissipation function. Polyurethane is designed for this function, for LED Driver, and that’s we are using. And the load is electronic type, not resistance type, this kind of load is very stable, to some extent, it can extend the life of the LED Driver. The LED Driver will be burned here two times, 4 hours(half load) for the first time and 8 hours(full load) for the second time.

• As for the electronics components, first class brand companies are our choices, we have cooperated with Infineon, Rubycon and NCC etc for many years, we are their big clients and the quality is guaranteed. The lifetime of LED Driver is limited by electrolytic capacitor, usually, the lifetime of good electrolytic capacitor is 5 years, and it is the warranty of our LED Driver. If you want to have a general idea of one supplier’s quality, you need to see the quality of their capacitor.

• In many cases, you are not able to fly to China to check the factory, but you can verify the company by its certifications. Here is what we have CE, FCC, CQC, RoHS, UL, cUL, BTW, the UL/cUL number is E362152.
