Description
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.
