Product Description COMPANY PROFILE:Shanghai Wenlida Technology Co., Ltd (hereinafter "Wenlida") is the largest manufacture base in China, the drafter of the national information industry standard, and the famous provider of voltage stabilizer.Wenlida has more than ten-year's glorious history. Since 1990, Beijing, Guangzhou, Changchun, Chongqing, Chengdu, Qingdao, Jinan and Suzhou office come into existence successively. In 2009, two new standard workshops and R&D center are established in Shanghai Jiading (37000m2) and Zhejiang Jiashan (45000m2) respectively.Wenlida has gained public praise for its advanced technology, excellent products, stable quality and first class service. Experienced in research and technology, system design, manufacture craft and products quality has made Wenlida to be famous in the power supply industry. In 1998, 2005 and 2007, Wenlida becomes the appointed supplier of Haier, ZTE and Huawei respectively. Also, it is the qualified supplier of MITSUBISHI,HITACHI,SIEMENS,DOOSAN,MGE,Hisense and OMRON.Nowadays, Wenlida is applying itself to the research and manufacture of clean energy, environment protection, energy saving, safety guard products. Based on the "specialized voltage stabilizer", "transformer" and "harmonic active filters", Wenlida will try to become the modern designer and manufacturer of new power supply.PRODUCTION INTRODUCTION:This series products, compared with other types, have the advantages of big capacity, high efficiency, small waveform deformation, smooth voltage regulation, wide range of load, the ability of resisting instant overload, long-term continuous operation, manual & automatic control method, protective function of over-voltage, short-circuit and mechanical transmission failure, little volume and weight, easy and convenient use, reliable operation,etc.. This series can be used as high quality alternative voltage stabilizing supply for industry, agriculture, transportation, postal offices, railway, scientific research institutes, precision machine tools, industrial production line, medical facilities, architectural engineering equipment and testing equipment, air condition, broadcast and TV stations and hotels.MODEL DESCRIPTION OF DIAGRAM:TECHNICAL PARAMETERS:Item No.Item NameItem Description1INPUT VOLTAGE (V)380V +/- 20%2WORKING FREQUENCY (Hz)50 / 60Hz3REGULATION MODESimultaneous phase regulation4CONSTANT VOLTAGE PRECISION+/- (1~5%) adjustable5NOISE (dB)55 dB6INSULATION CLASSF7OPERATION TIME (hr)≥ 100,000 hours8PROTECTION CLASSIP 209VOLTAGE WITHSTANDING2000V, 1min.
