Description
Performance:
• Double conversion online design, 0ms exchange output, single input and single output voltage.
• With DSP digital control technology, Excellent performance index, the control system more stable and reliable.
• With active power factor correction technique (PFC), Input power factor close to 1, greatly reducing the pollution of the electricity grid.
• Ultra-wide input voltage range.
• Input frequency range of 40~70Hz, to ensure access to a variety of fuel generators can work.
• LCD + LED using real-time display, the user can intuitively understand the operating state of the UPS.
• Has turned self-diagnostic function, can detect hidden faults of UPS.
• With AC input over-voltage and under-voltage protection, output overload protection, short-circuit protection, temperature protection, battery under-voltage warning protection and battery overcharge protection, etc.
• Overall efficiency 94.5% reduction in power loss of UPS, saving the user’s cost.
• When there is no utility power, it can directly use the battery to start working.
• When the utility power is restored, the UPS can automatically turn on and charge the battery at the same time to realize the unattended function.
• When the electricity is interrupted, UPS will discharge untill power off during battery mode.
• The standard RS232 communication interface enables multi-functional and multi-purpose monitoring and management operations between the UPS and
computer through a computer window, and an SNMP card (optional) can be installed to realize the UPS remote monitoring function.
