OPTI-UPS was established in 1991. The company was under the ViewSonic group initially and independent later for higher brand value. With enthusiasm to serve, we always place customer satisfaction as our priority. The acquisition of ISO 9001 certification and production over wide range of UPS models has been the two approaches used to achieve such goal. All products are designed with features of user-friendly installation and extended run times for wider applications. In order to serve our customers with greater efficiency, OPTI-UPS has set up branch offices worldwide, which cover USA, Germany, UK, Czech Republic, Australia, Taiwan and Dubai, as well as logistic facilities in Holland, Czech Republic, Dubai and USA. In general, most of our UPS systems can be plugged directly; yet for high level application or special customization, estimation of load requirements and backup time must be accurately done. Further to mere delivery of goods, we guide customers from formulation of their demand and installation to maintenance of a power supply system. For after-sale support, we provide thorough and prompt services in consultation, configuration, maintenance and repair. Moreover, we conduct regular product updates and technical seminars to benefit our partners. Our confidence in superior quality and more than 19 years of solid achievements have satisfied customers worldwide with continuous growth for all parties every year. Furthermore, we provide 2-year warranty on both UPS products and internal batteries, which contains various extension programs from OPTI-UPS directly or local partners worldwide.
