Online UPS

XST Series


  • Eco-Mode high efficiency  configuration  — Operating  mode  that  switches  the  UPS  to  static bypass  during  normal  operation.  When  power problems  are  detected  the  UPS  automatically switches back to double conversion mode. 
  • High overload protection  —  The  system’s  static switch  overload  rating  makes  it  capable  of  handling 125%  for  10  minutes,  150%  for  one  minute  and  a 1000% overload for 10 milliseconds. 



  • Online double conversion mode with an output power factor of 0.9 providing 12% more active power compares to UPS with a power factor of 0.8.
  • Dual input mains allow you to manage independent power sources
  • Increased system availability placing UPS in parallel for N+X redundancy .
  • Internal manual bypass for easy maintenance without power interruption .
  • Up to 12pcs parallelable
  • Multilanguage big LCD display

HIGH PERFORMANCE PFC RECTIFIER Thanks  to the  technology  used,  XSM / XST  solves  installation  problems  in  systems  where  the  power supply  has  limited  installed  power,  where  the  UPS  is  also  powered  by  a  generator  or  where there  are  compatibility  problems  with  loads  that  generate  harmonic  currents;  XSM / XST  has  zero impact on its power source, being either the mains power supply or a generator:

  • Input current distortion of less than 3%
  • Input power factor 0.99
  • Power walk-in function that ensures a progressive start-up of the rectifier
  • Start-up delay function, to restart the rectifiers when mains power is restored if there are several XSM / XST in the system.

In addition, XSM / XST plays a filter and power factor correction role in the power network upstream of the UPS, as it  eliminates  harmonic  components  and the reactive power, generated by the powered utilities.

Built-in  automatic  bypass  —  Transfers  the  load  to bypass in the unlikely event that a fault occurs in the UPS.

Optional  maintenance  bypass  distribution  cabinet  —  Provides  complete  wrap-around maintenance  bypass  allowing  XSM / XST  to  be  powered  down  or  taken  out  of  service  without disconnecting power to the load. 

Optional  internal  batteries  —  Batteries  can  be  housed  within  the  XSM / XST  itself.  Easy  change of batteries with internal drawer type shelves.  Optional  XSM / XST  looking  external  battery  cabinets  —  Provide  added  back-up  capacity  for extended runtimes. 

  • Monitoring of the switches and external bypass — Switches can be monitored through LCD and Modbus.

Advanced communications

XSM / XST is equipped with a back-lit graphic display providing UPS information, measurements, operating states and alarms in different languages. It can also display wave forms and voltage/ current forms

Maximum reliability and availability

  • Adjustable battery quantity: 20 to 40pcs.
  • Lowers spare part cost by using same boards for different ratings

Triple-mode  Intelligent  adjustable  battery  charger  for  fast  battery  recharge  —  Three charging modes ensure maximum battery availability:

  • Constant current charging provides maximum rated current to the battery until the voltage rises to a pre-determined limit.
  • Constant voltage charging allows the batteries to recover the final percentage of recharge capacity. A boost voltage is provided for a short term to reduce the battery recharge interval.
  • Float charging maintains the battery at the recommend voltage.

Adjustable battery charging time due to the level of the load to save from energy cost
