UPS standby power supply series Description: Characteristic description 1. Application fields Standby power supply for: Communications and telecommunications stations, Power plant, Power transmission system, Computer protection system, Emergency power supply(EPS), Uninterruptible power supply (UPS) system, Radio and broadcasting station & automatic control system 2. Executive standards： GB/T 19638-2014<< Stationary valve-regulated lead acid battery>> IEC 60896-21/22:2004 <> YD/T 799-2010 <> YD/T 1360-2005 <> 3．Integrated Performance: (1) Green and environment-friendly: the plate made of special alloy, which is environment-friendly. Imported nanoscale fumed silicon is adopted in gel battery; there will no leak of electrolyte even if the case broken, enhance environmental safety. (2) Low self-discharge: Adopt high purity raw materials, optimized design and technology, the battery not needed charging after storage for over 6 months at room temperature. (3) High-rate discharge performance: adopting optimized design and low resistance components, make a high discharge efficiency and high rate discharge performance. (4) Maintenance free: special design for oxygen recombination, make few water loss of electrolyte under normal operating( called oxygen cycle),maintenance of water added is not needed. (5) High safety: single-track valve with pressure balance, acid fog filter, anti-flaming and anti-explosion function. (6) Long cycle-life: pseudo-flooded electrolyte without acid stratification in gel electrolyte and anti-corrosion rare-earth alloy; no acid liquor layer, these performances can delay the electrolyte loss and plate corrosion, and enhance the cycle-life.
