| NOTE | 1. All parameters NOT specially mentioned are measured at 230VAC input, rated load and 25℃ of ambient temperature. 2. Derating may be needed under low input voltages. Please check the static characteristics for more details. 3. Tolerance: includes set up tolerance, line regulation and load regulation. 4. Ripple & noise are measured at 20MHZ of bandwidth by using twisted pair-wire terminated with a 0.1uf & 47uf parallel capacitor. 5.The power supply is considered as a component that will be operated in combination with final equipment. Since EMC performance will be affected by the complete installation, the final equipment manufacturers must re-confirm EMC Directive on the complete installation. 6.The start time was tested under the situation of cold star, continuous switching on/off may raise the start time. |

Advantages
1,The first factory entered the waterproof LED Power Supply in China mainland;
2,10 years focus on the LED Power Supply Research and development, Production;
3,Serviced 2,500 customers, including 2000 in China mainland, 500 in overseas markets all over the world;
4,High reliability and good stability, for many kinds of large-scale outdoor lighting project, through the use of test from 2500 customers;
5,LED Power Supply is the heart of the LED lamps and transformers is the core component of LED Power Supply. For control the quality, we made the transformer by our own factory, this also for the power supply is stable and reliable;
6,Complete certification, UL, SAA, EMC etc., Small factory often lack of this;
7,Electrolytic capacitors and other components are made of giant brand, high-end products with Ruby etc.
8,After-sale guaranteed, real integrity transactions, 1:1 replace the faulty item, but many small factory often irresponsible when face the quality problem, even precarious;
9,Strictly process control, Power supply enter the door is low, but do well is not much, do not do well, even though the same techniques, the same material, do all the things we are not the same, because process control are not the same, Equipment is not the same;
10,Strong r&d team, r&d team has more than 30 people;
11,Flexible and fast delivery, bulk orders usually delivery within two weeks, General small batch orders can be arranged delivery within 3 days if have semi-finished products in stock;
12,Compare with MeanWell, we have the advantages of ODM, OEM, quality unchanged and have competitive price.
