CHARACTERISTICS

  • True OnLine technology Double Conversion provides excellent output voltage performance regardless of power interference and the type of consumers being powered.
  • IGBT rectifier The most advanced technology providing very low THDi and high power factor.
  • Automatic bypass - uninterruptible 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:
  • - RS232, RS485, MODBUS 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,
  • Connector for Remote Emergency Power Off. (REPO) for providing remote disconnection of power supply to consumers in case of fire,
  • Fire Protection Switch. (EPO) on the control panel allows you to immediately disconnect the power supply from the consumers,
  • LCD control and monitoring panel and LED indicator gives the possibility to diagnose the parameters and mode of operation of the power supply, enables the registration of events and, among other things, a graphical preview of current and voltage waveforms.
  • Small dimensions The UPS has the ability to install batteries internally, so no additional space is needed for basic backup times.
  • High efficiency of the device (>95%) reduces the emitted heat, making eventual cooling of the premises simpler and cheaper.
  • ECO-Mode allows a significant reduction in the cost of operation of the device and virtually eliminates the emission of heat.
  • Motor Mode Function Allows switching on devices with higher starting current. In this mode, the inverter is started first and then the loads are switched on. Starting from the inverter limits the inrush current of the load without putting the UPS into bypass mode.
  • Normal operation function in case of power phase failure allows you to save batteries. The UPS operates normally without the use of batteries up to a load of 56% without the presence of one phase, and up to a load of 28% without even two power phases available.
  • Automatic diagnostics and digital control (32 bit DSP x2) guarantees full efficiency of the device, control of components and operating parameters without user intervention.
  • High input power factor value of 0.99 limits the value of the current drawn by the device from the network.
  • Highest output power factor value of 1.0 allows the power supply to be loaded with full active power.
  • Wide input voltage range w trybie pracy normalnej zapewnia stabilną pracę urządzenia bez the need to use 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 easy connection to the network and simple switching on and off of the device does not require any 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
