This series of UPSs is the ideal emergency power supply solution for protecting critical equipment from power blackouts, brownouts and surges. A typical application is that during a power outage this UPS enable an elevator system to come to the nearest floor and door to open so that people would not get stuck in an elevator. Features  Wide input voltage range  Selectable LCD display, 3 LED display and 6 LED display  Microprocessor-based digital control  Intelligent battery management  Unattended function available  Support starting and running without battery  Superior protection and automatic system recovery  Wall / vertical mounting

A line-interactive UPS maintains the inverter in line and redirects the battery's DC current path from the normal charging mode to supplying current when power is lost. In this smart design, the battery-to-AC power inverter is always connected to the output of the UPS. When the input AC power is normal, the inverter of the UPS is in reverse operation and provides battery charging. Once the input power fails, the transfer switch will open and the power will flow from the battery to the UPS output. This design offers additional filtering and yields reduced switching transients since the inverter is always on and connected to the output.

LED display or LCD display selectable Microprocessor-based digital control Boost and buck AVR for voltage stabilization Auto sensing frequency Wide input voltage range with dual input voltage (115V & 220V) Power-on self test Cold start Auto restart when mains power is restored Auto track mains phase to ensure that inverter output voltage has same phase with utility voltage, reducing transfer time and peak surge Intelligent battery management: battery temperature compensation to extend the battery life; three-stage charging to shorten recharge time Short circuit, battery overcharge / overdischarge, overload, surge protections Automatic charging in OFF mode Optional no-load shutdown Optional RS232 / USB communication port and RJ11 / RJ45 protection Unattended safety shutdown: system alarm and auto Power-On / Off by RS232 or USB interface communicating with PC
