• Adopt the imported or joint venture automatic transfer switches (two-supply switch); the products adopt micro-motor pre-power storage and micro-electronics control technologies; the biserial combined contact terminal and the horizontally drawing structure realize zero overflash; the switches possess double protections of electric interlocking and the mechanical interlocking, adopt the zero passage technology, setting zero in the emergency (cut down the two-path power supply at the same time); distinct on-down position indication and padlock; and realize the isolating mechanical and electronic integration between the power supply and the load. The switch owns multi-path input/output interface, which is simple to realize long-distance PLC control and systemic automatization. Equipped with both national and international famous electronic parts, and manufactured through the optimized design, it satisfies the requirements of the UPS and the clients.

• Simple, small, nice appearance, convenient to operate, and long service life.

• Good safety stability; three safety positions (I-0-II) realize the load automatic transfer; the distinct off state realizes the safety isolation; operate it manually in the emergency.

• Short transfer time; mechanical and electronic integration interlock dual protection device; safer.
