LED Tester | Christmas Light Tester - LISUN

During electromagnetic radiation test, three loop antennas are often used. Lisun three loop antenna VVLA-30M is a standard measurement antenna according to CISPR15-2005. It can coordinate Lisun EMI-9KB or EMI-9KA EMI Receiver System for EUT magnetic field radiation test measurement between X, Y and Z planes. VVLS-30M is a big antenna with 2m diameter, which is used for testing frequency below 30MHZ radiation electromagnetic field, frequency range is 9 KH z~30MHz. The limits for the 2m loop diameter apply to equipment not exceeding a length of 1.6m. Three loop antenna fully meets the requirements of standard CISPR-2005 and GB17743, which is suitable for measuring work frequency over 100HZ luminaries radiated magnetic field disturbance. The bottom above ground distance is 0.5m, special design current converter with shielding. VVLA-30M is an antenna with three axes, which can switch between X, Y and Z. The sensor coefficient of current probe is 0dB. Impedance is 50Ω/BNC. The volume ...

In recent years, many manufacturers are planning to manufacture common global LED drive products with a wide voltage input. But since different countries have different product standards, it results in some difficulties and obstacles in the design and production. This article compares and analyzes the differences of LED driver design and test safety standards between the North American ANSI / UL 8750 standard, and European EN 61347-2-13 (to be used with EN61347-1) standard. 1. The differences in standards:   1) Products The title of UL 8750 standard is Light Emitting Diode (LED) Equipment for Use in Lighting Products. These LED equipment include not only LED drivers, but also LED modules, LED controllers, and so on. However, the title of EN 61347-2-13 is Particular requirements for d.c or a.c supplied electronic control gear for LED modules.  The products covered are just LED electronic controls. Therefore, from the scope of products covered in the standards, we...

1. In this new system, we integrated the big Integrating Sphere with the small one. So that the connection will be much convenient and easier. 2. We also integrated the Spectroradiometer, power supply and other instruments all in a whole cabinet, that makes the system looks very compact and beautiful. 3. This system has powerful software as well, it's stable and easy to operate. At the same time, the test report has been accredited by the Third Party Lab, which shows it has great test accuracy and reliable test stability. 4. The last and the most important is the price of this system is very competitive, and affordable for nearly every customer.

It is according to IEC60695-2-1, IEC60695-2-10~IEC60695-2-13, basic testing methods of Glow wire, basic testing methods of Glow wire device and UL 746A, IEC829, DIN695, VDE0471, the Glow wire tester ZRS-3H is suitable for resistance to abnormal heat and fire test on lighting lamps, electronic products and household appliances. Adopting high-temperature coating spraying on steel structure and imported instrument display, with easy operation, stable performance the equipment is applicable to flame resistance tests of all levels of QC departments and corresponding enterprises.
