• With double conversion online design, zero output transfer time.
• Adopt DSP digital control, excellent performance indicators, more steady and reliable.
• Adopt the technology of active power factor correction technology (PFC), the input power factor is close to 1, which greatly reduces the pollution to the mains power grid, and achieves the purpose of energy saving and reducing system investment costs.
• Output voltage 100Vac/110Vac/115Vac/120Vac/127Vac can be set
• Ultra-wide input voltage range, input voltages available 110V instead of turn to battery power.
• With LCD+LED real-time display, UPS operating available for detection.
• With self- detection function, can detect hidden faults of UPS.
• Cold start by battery without grid Input.
• Input frequency range 40~70Hz, support various fuel generators.
• With AC input over voltage, low voltage protection, output overload protection, short circuit protection, temperature protection, battery low voltage warning protection and battery overcharge protection.
• Output power factor 1.0 max. efficiency reach 95% , reduce loss of UPS .
• When utility cut-off, the UPS discharge battery in the battery mode; when the city power is recovery ,UPS turn on automatically,and charge battery at the same time, asunattended function.
• Standard RS232 communication outlet ,connect UPS and computer to realize multifunctional and multi-purpose monitoring and management operations, available SNMP card (optional) to UPS remote monitoring function.
