Products detail

Technical parameters

UPS overview

  • DSP technologyThe advanced DSP digital control technology enables the UPS to deliver more stable performance.
  • Environment friendlyThis UPS is eco-designed and manufactured to meet the China local pollution control requirement of Electronic Products, which means it will cause no harm to the environment and human beings in normal usage.
  • Active input power factor correction (PFC)Digitalized control of the PFC enables the UPS to keep its input power factor above 0.99 to prevent possible electric grid pollution and meanwhile mostly save the cost.
  • Widened range of input voltage and frequencyWe intentionally widen the range of input factors to make sure the UPS can apply to various environments, which will effectively sustain the battery charging even in an unstable power environment so that the service life of the UPS could be obviously prolonged.
  • Zero power switch delayWhen the utility power fails, the UPS will automatically switch from AC mode to battery mode with no delay, which ensures a stable power supply for the operating system.
  • Adaptive load managementThis technology allows the UPS to be set up at a fixed 50Hz or 60Hz output, while it also can intelligently monitor power usage and automatically shed and reconnect loads in order to prevent generator overload.
  • Sufficient expansion slotsThe pre-allocated smart slots enable flexibility in the choice of USB cards, AS400 cards, CMC monitoring cards, SNMP cards, RS485 cards and EMD environment monitoring cards.
  • Load power factor 0.9It adapts the features of most current electric equipment and elevates the load-bearing capacity of the machines.
  • Support the generatorsThe wide range of input voltage and frequency can effectively separate the harmful electric wave produced by the generators and provide a safe and reliable power supply.
