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:
VFP series intelligent variable frequency power supply is the new-generation and stable-frequency power supply equipment developed by our Company. It is satisfies the special requirements which can simulate the power supply environment of different countries in the world. It can also provide power supply for test of exported domestic equipment.
To design the variable frequency power supply (VFP), Wenlida used ARM's new generation 32-bit processor as the core, IGBT as the executive element, and isolation transformer for voltage conversion. And then, in order to meet the different voltage and different frequency value, Wenlida adopts the SPWM (Sinusoidal Pulse Width Modulation) conversion method to switch the input power as AC-DC-AC.
