The UV module of the PV module mainly specifies the test of the UV module when the PV module is exposed to the UV radiation environment. This test is suitable for evaluating the UV resistance of materials such as storage polymeric materials and protective layers. performance. Specifically for the solar industry to do the aging test of the solar component category. PV module UV test chamber can be customized according to customer's requirements.

12, power supply: AC220V 50HZ
13, total power: 4KW
14. Standard accessories: 1 sample shelf, 8 imported lamps, 1 hand-held irradiation meter
1. The outer shells are made of high-quality (t=1.2mm) A3 steel plate CNC machine tool, and the surface of the outer casing is sprayed, which is more smooth and beautiful.
2. The inner chamber material is made of brushed SUS304B board, which has the characteristics of acid resistance, corrosion resistance and easy cleaning;
3. The sample holder can adjust the position of the upper and lower as needed;
4, according to the historical experience professional design of experimental equipment, has a reasonable air circulation system, so that the temperature inside the box reaches the highest uniformity;
5. The distance between the test piece and the surface of the lamp is parallel: the highest level meets the test irradiance requirement of the sample (the height of the test piece can be adjusted).
The temperature can be automatically monitored; the illuminance meter can be configured to control the irradiance of the lamp by voltage regulator to adjust the irradiance to the specified illuminance and control the test time.
STT-R series platinum resistance temperature sensor; it is packaged in stainless steel case, filled with heat-insulating material and sealing material. It is small in size and excellent in waterproof and shockproof performance up to IP67.
1. The center distance of the lamp is 70mm. Refer to the PV industry component size. The size of the solar module is 1680mm, and the calculation is based on the use of 6 lamps; (additional 2);
2. UV-A and UV-B UV fluorescent lamps with a rated power of 40W. The ultraviolet fluorescent tube is installed on the top layer of the instrument;
The luminescence spectrum energy of the UV-A tube is mainly concentrated at the wavelength of 340 nm. The luminescence spectrum energy of the UV-B tube is mainly concentrated at the wavelength of 313 nm, which is a continuous spectrum roughly distributed at 280-400 nm, and the energy ratio is 2:1. ;
3, because the fluorescent light energy output will gradually decay with time, in order to reduce the impact of the test caused by the attenuation of light energy, and GB/T 19394-2003 No.5-a requirements for irradiation uniformity ± 15%, this The test chamber is designed with a lamp current control system to obtain a constant output of light energy.
