Performance: • Double conversion online design, output zero conversion time. • Adopting DSP digital control, with excellent performance indicators, making the control system more stable and reliable. • Using active power factor correction technology (PFC), the input power factor is close to 1, which greatly reduces the pollution to the mains grid. • Ultra-wide input voltage range, the input voltage can be as low as 208V without switching to battery power supply. • Automatically recognize and adapt to the 50/60Hz power system, can be connected to various fuel generators and can work stably. • With LCD LED real-time display, users can intuitively understand the UPS operating status. • Self-diagnostic function at startup, which can detect the hidden failure of the UPS in time. • With AC input over-voltage and under-voltage protection, output overload protection, short-circuit protection, temperature protection, battery under-voltage warning protection and battery over-charge protection, etc. • The efficiency of the whole machine is as high as 94.5%, which reduces the power loss of the UPS and saves the user’s use cost. • The standard RS232 communication interface and an SNMP card (optional) can be installed to realize the UPS remote monitoring function. • When there is no utility power, you can directly use the battery to cold start. • With input phase sequence protection function, the phase sequence cannot be turned on when the phase sequence is reversed.
