Riello – Brand new 160 to 200 kVA models for Multi Sentry Range


January 13, 2015

Riello UPS is pleased to announce the new Multi Sentry 160-200 kVA, the brand new models of high efficiency and ultra compact UPS of the Multi Sentry family.

MST160200_01Riello UPS enlarges  its  offer  adding  Multi  Sentry  MST  160  and  200  on  the  product portfolio. This product integrates the existing three phase  MST range 10-120 kVA to offer a  complete large selection of  transformer less  UPS from 10 to 200 kVA. With 12 different power ratings it satisfies any critical power demand (10,  12,  15,  20,  30, 40, 60, 80, 100, 120, 160, 200)

MST 160-200 enlarge Multi Sentry family therefore it follows the general design structure and the UPS operations approach (same logic, same LCD display navigation menu) Nevertheless, MST 160-200 is at the cutting edge of UPS development taking on board the latest three level inverter technology and intelligent control which grant:


– kW = kVA  (output pf =1)
– Very high efficiency (>96%)
– Smart ventilation (saving energy and reduce noise)

kW = kVA

The unitary  output  power  factor grants  higher  active  power availability  (+11%  compare  to UPS with pf 0,9). Furthermore,  MST  supplies capacitive loads with PF from 1 to  0,9  with  no  power downgrading applied; therefore it is suitable for any data center application  with  unitary  or capacitive  power  factor  (new server  generations  which commonly  work  between  unity to 0,95 leading PF). In  response  to  any  tender requirement  for  UPS performances  under leading/lagging  load  applied,  MST  operates  properly  whatever  is  the  load  power factor range applied.


MST160200_03Very high Efficiency

State-of-the-art three-level NPC inverters  grants  an  overall  UPS efficiency greater than 96%. Efficiency  overcomes  95% starting  from  22%  load  level guarantee  high  efficiency regardless  the  UPS  load  level; this  result  in  minimizing  the losses  and therefore the energy cost  at  any   operating  load condition.

Smart ventilation

Smart  ventilation principle on MST  160-200  manages  the  number  of  operating  fans  and  their  speed  according  with  room  temperature  and  load  level.  So  doing  we  preserve  fan’s  life  span and at same time  we  reduce  noise  level  and  overall  power  consumption  for  unnecessary  UPS  ventilation.
