Our Advantage

  • Strong product technology and performance advantages

    Strong product technology and performance advantages

    Since its establishment in Taiwan in 1990, Merry King(PANFORE) has been a leader in power adapters and transformers for more than 20 years. The company has established a sound R&D and incentive mechanism through a stable team and through Taiwan's international team. R&D work has always been the top priority. Through the “first step” research and development concept and the new product development policy of “production first generation, improved generation, and concept generation”, we have fully grasped the market and product direction and made great achievements in product research and development. success. Through continuous independent research and development and technological innovation, the company's R&D team now has resonant technology (zero voltage and zero current switching technology), quasi-resonant technology (valley/zero voltage switching technology), low power frequency reverse walking technology, and interleaved active PFC. Leading power-related core technologies in industries such as resonant technology. The continuous R&D investment and rich research and development results make the company's switching power supply products fully integrated with international standards in terms of energy efficiency, output accuracy, power factor, dielectric strength, working environment temperature, surge registration, and waterproof rating. In national standards, industry standards and industry common standards.

    1 High reliability: The patented technology realizes high-precision current constant and small harmonics, truly achieving stable and reliable quality, and the defect rate is less than 5/10,000; 2 Ultra-high efficiency: low standby power consumption, constant voltage efficiency up to 95%, power The factor is up to 0.99, which is truly energy efficient; 3 long life: working life of more than 50,000 hours, and can work normally at -40 ° C - +70 ° C temperature; 4 super strong characteristics: ultra wide input voltage 90-305V (With undervoltage and overvoltage protection), waterproof rating up to IP68 standard, anti-radar to 4KV or more, with over-voltage, over-current, over-temperature and other multiple protection; 5 intelligent control: realizing time intelligent control, 0-10V simulation Dimming, DALI intelligent stepless dimming, PLC intelligent remote stepless dimming, RS485 or DMX512 intelligent remote stepless dimming, infrared sensing intelligent control and other functions, indoor thyristor dimming, to achieve the "secondary energy saving" of LED lighting 6 Light and beautiful: the application of new materials, new processes, product modularization, standardization, easy to install and maintain, to achieve small size, light weight, green and environmentally friendly.

  • Global certification system and product certification advantages

    Global certification system and product certification advantages

    As a world-renowned manufacturer of power adapters and transformers, Merry King(PANFORE) has been keeping up with the industry trend and is at the forefront of the industry in the field of power supply safety and energy conservation. Power product certification has always required a long time and a high cost. Due to the rapid replacement of related products, and the update of international standards is changing with each passing day, the performance of products must be constantly updated and updated according to the corresponding standards and energy-saving requirements. Now we have a full range of UL, GS, BS, CE, CB, PSE certification; in addition, in order to obtain the unique customer's purchasing rights, we also have to meet the customer's individual requirements through relevant customer certification. At present, all the power products of Merry King(PANFORE) Company fully meet the world's latest energy efficiency standards and EU ROHS environmental protection requirements. The company's series of power products have complete safety certification and have gradually become the mainstream power supply suppliers of multinational companies.
