CHARACTERISTICS

  • True OnLine technology True On-Line Double Conversion technology ensures excellent output voltage performance regardless of power interference and the type of loads being powered.
  • IGBT rectifier The most advanced technology providing very low THDi and high power factor.
  • Automatic bypass Uninterruptible power supply provides uninterrupted power to consumers in critical situations like overheating or failure.
  • Service bypass allows servicing of equipment without shutting down the powered loads. Separate power supply of the Bypass track gives the possibility to provide a backup power source for the consumers even in case of equipment failure or UPS protection tripping in the main track.
  • Communication interfaces:
  • - USB, RS232, IntelliSlot for monitoring and managing the operation of the power supply and receivers,
  • - DryContact relay contacts for interfacing with BMS systems
  • - SNMP integration with NMS-type network management systems
  • - Remote Emergency Power Off (REPO) connector. (REPO) for providing remote disconnection of power to consumers in the event of a fire,
  • - The Fire Protection Switch. (EPO) on the control panel allows you to immediately disconnect power to loads,
  • 4.3" LCD color touchscreen control and monitoring panel simplifies UPS operation, allows diagnostics of parameters and operating mode of the power supply, and enables event logging.
  • Small dimensions The UPS has the ability to install batteries internally, so no additional space is needed for basic backup times.
  • Very efficient charging system makes the UPS capable of quickly charging battery banks with very large capacities, for long autonomous operation times.
  • High efficiency of the device (>96%) reduces the emitted heat, making the eventual cooling of the premises simpler and the UPS much cheaper to operate.
  • ECO-Mode allows a significant reduction in the cost of operation of the device and virtually eliminates the emission of heat.
  • Automatic diagnostics and digital control (32 bit DSP x2) guarantees full device performance, control of components and operating parameters without user intervention.
  • High value of input power factor 0.99 limits the value of the current drawn by the device from the grid.
  • Highest output power factor value 1.0 allows the power supply to be loaded with full active power.
  • Wide input voltage range in normal operation mode ensures stable operation of the device without the need for batteries, which significantly extends their life.
  • Wide input frequency range in normal operation mode allows the power supply to be used freely in a network with unstable parameters and when powered by a generator set.
  • Ease of use The ease of connection to the network and the simple switching on and off of the device does not require special qualifications from the user.
  • Advanced battery management guarantees optimal charging and utilization of battery banks, increases battery life and reduces operating costs. Temperature compensation function of charging voltage.
  • Excellent output voltage quality achieved through the use of a 3-level IGBT inverter, with the use of advanced PWM control technology makes it possible to deliver a voltage with stable parameters, regardless of energy disturbances and the type of powered devices.
  • High overload capacity Ensures protection of the device and continuity of power supply in the presence of transient transients.
  • Advanced software enabling the user to have full control over the device and the powered loads.
  • Configurability of operating parameters nominal voltages, frequencies, preferred modes of operation, method of communication - greatly expands the range of possible applications.
  • Redundant configurations:
  • - Redundant parallel operation for increased reliability
  • - Capacitive parallel operation for increased power
  • - HotStandby work
