Yiguang Technology

After half a year of efforts by the technical staff of Shenzhen Yiguang Technology Co., LTD., the LY series of 75W, 96W, 120W, 150W, 200W and 240W LED driver power supply was upgraded to meet the TUV certification requirements. In particular, TUV certification in 2014 after the LED power dimming products of harsh harmonic requirements and temperature protection requirements, complete the company in the high power range LED power series TUV certification, enhance the company's product competitiveness. To meet the demand of LED drive power used in LED street lighting in the Chinese market and the European market.

This TUV certification, 81 basic models, a total of 243 TUV models.

LY series products TUV certification, LED controlgear, SELV, independent, isolated, Class I, IP67.

Product EMI conforms to:

EN55015:2013/A1:2015, EN61547:2009, EN61000-3-2:2014, EN61000-3-3:2013

Products EMS comply with:

EN61000-4-2, EN61000-4-3, EN61000-4-4, EN61000-4-5, EN61000-4-6, EN61000-4-8, EN61000-4-11, EN61547

LY series products, with constant current, constant voltage and 0-10V dimming functions, and has a separate constant current TUV certification, constant voltage TUV certification, dimming TUV certification.

LY series LED power supply adopts QR technology and LLC technology, and adopts the sixth generation COOLMOS new devices and modules to integrate LLC technology, so that the energy conversion efficiency of the product is as high as 95%, greatly reducing the internal temperature rise of the product, and improving the product life.

LY series LED power supply uses Active PFC(Active PFC) power factor correction technology. Under full load condition, the power factor reaches 99% at 120V input, 97% at 230V input, and the total harmonic THD distortion is less than 15%.

LY series LED power supply with metal aluminum shell, with thermal silicone potting. The internal temperature rise and failure rate of the product are reduced.

LY series LED power supply optimized temperature design and use of long-life electrolytic capacitors, so that the life of this series of products to reach more than 50,000 hours.

LY series LED power supply with a two-stage surge absorption circuit and a first-stage lightning arrester, so that the product can withstand industrial grade instantaneous lightning surge 4KV capability (EN61000-4-5), suitable for outdoor lighting applications.

LY series LED power supply has a wide input voltage range of 100-240V, which meets European grid standards.

LY series LED power supply has three types, respectively: constant current type, constant voltage type, 0-10Vdc dimming type. For dimming products, add "-RD" to the suffix of the product model. Dimming type products will add two control lines.

LY series LED power supply uses natural cooling technology to work in the temperature range of -30℃ ~ 60℃. To meet the requirements of users around the world in indoor and outdoor use of the working environment.

LY series LED power supply with short circuit protection, overload protection, overvoltage protection, overcurrent protection. The product is used in LED street lights, LED tunnel lights, LED projection lights, outdoor LED electronic billboards, LED decorative light sources, indoor and outdoor LED lighting, etc. In addition, the product is ideal for industrial outdoor applications that require dust resistance and high humidity.
