UPS

● Microprocessor-based digital control ● Boost and buck AVR for voltage stabilization ● Auto sensing frequency ● Wide input voltage range ● 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 USB communication port and RJ45 protection ● Unattended safety shutdown: system alarm and auto Power-Off by USB interface communicating with PC
