etc.). Whateve

r type of load to protect is, the equipment is ready to 

assure the quality and uninterruptible electrical power supply. 

The  use  of  the  transformerless  technology  allows  a  significant 
reduction  of  weight  and  volume  in  the  equipment,  by  improving 
important co-efficiency a lot like the power/footprint ratio. 
•    Basically its operating is the following: 

 

The rectifier, an IGBT three phase rectifier, converts the 
AC  voltage  in  DC  by  draining  a  sinewave  current  (THDi 
<2%),  charging  the  batteries  with  constant  
current/voltage. 

 

Batteries supply the energy required by the inverter in case 
of mains fault. 

 

The inverter is in charge of converting the DC bus 
voltagein to AC by providing an alternating sinewave output, 
stabilizing voltage and frequency, ready to supply the loads 
connected at the output. 

 

The basic structure of double conversion is complemented 
with two new functional stages, static bypass switch and 
manual bypass switch. 

 

The static bypass switch connects the output load  with 
bypass line directly in special conditions like overload or 
over temperature and it is reconnected to inverter again, 
once the normal conditions are restored. 

 

UPS  B 

version  has  two  separate lines  for  the rectifier 

and bypass stages increasing in the safety of the 
installation, because it allows the use of a second line 
(generator set, other company, etc...). 

 

The manual bypass switch isolates the UPS from mains and 
loads connected at the output, so the maintenance tasks 
can be done inside the UPS without interrupting the supply 
to the loads. 

 

 

4.4.1.  Normal operating (

). 

 

With mains present, the rectifier converts the AC input voltage into 

DC,  by  boosting  the  DC  voltage  to  an  optimal  level  to  feed  the 
inv

erter and battery charger. 

The inverter is in charge of converting the DC bus voltage into AC 
by  providing 

an  alternating  sinewave  output,  it  stabilizes  the 

voltage and frequency, ready to supply the loads connected at the 
output (Fig. 20 and 21).

 

 

4.4.2.  Mains fault operating (

).

 

 

In  case  of  mains  fault  or  blackout,  the  battery  set  supplies  the 
needed energy to feed the inverter.

 

The  inverter  stil

l  operates  normally,  without  noticing  the  lack  of 

mains and the back-up time depends on the capacity of the battery 
set only (Fig. 20 and 21). 
When  the  battery  voltage  reaches  the  low  voltage,  the  control 
blocks the output in order to protect the batteries from being deep 
discharge. When mains is restored and after the first analysis, the 
UPS  goes  back  to  operate  as  it  is  described  in  the  previous 

section «4.4.1. Normal operating».

 

 

4.4.3.  Operating with non-active inverter (

). 

 

The  inverter  is  non-active  due  to  alarm  conditions  like  overloads, 

over temperatures, etc... In this case the rectifier is still charging the 
batteries in order to keep their optimal charge status.

 

The  inverter  is  a

lso  non-active  if  the  start-up  has  not  been  done 

through the keypad of the control. 
In  both  cases,  the  output  voltage  of  the  UPS  comes  from  the 
emergency bypass line through the static bypass switch (Fig. 20 and 
21) in the condition that t

he EPO is inactive. 

 

4.4.4.  Manual bypass operating (

).

 

 

When  it  is  required  to  make  any  maintenance  service  to  the 
equipment,  it  can  be  disconnected  from  mains  without  breaking 
the  power  supply  of  the  sys

tem  and  affecting  the  critical  load. 

The UPS can only be intervened by technical or maintenance staff, 

by means of the manual bypass switch (respect the corresponding 
operative instructions stated later on)

 

 

4.4.5.  Smart Eco-mode operating.

 

 

For  those  applications  with  lower  requirements,  the  smart  and 
efficient  function  «Smart  Eco-mode»,  meanwhile  the  power 
supply is available, allow the equipment to feed the loads directly 
from mains through the solid static bypass state («Off Line» mode). 
In case of mains fault, the system will automatically shift to normal 
operating mode («On Line»)  and will supply the  loads through the 
inverter  with  the  energy of  the  batteries.  The  «Smart  Eco-mode» 
operating  mode  improve  the  efficiencies  between  4  and  4.5  % 
highest than «On Line» normal mode, so it is close to 100 %. 

The  «Smart  Eco-mode»  operation  does  not  ensure  a  perfect 
stabilization  in  frequency,  voltage  or  sinewave  sh

ape  (distortion) 

as  in  «On  Line»  normal  mode,  because  the  figures  of  these 
parameters depend on the static bypass line and preset activation 
ranges completely. 
The  detection  of  these  parameters  can  take  up  to  3  ms,  so  it  is 
recommended  to  assess  the  advisability  of  using  this  operating 
mode, de

pending on the level of protection required by the loads. 

This operating mode is disabled from factory and the end/user can 
activate it if needed, according to section 7.2.2. and Fig. 35. 

 

This operating mode is disabled from parameters and the end/user 
can activate it if needed 

 

4.4.6.  Frequency converter operating.

 

.

 

This UPS

 

can be set from factory as frequency converters, whether 

they has 

batteries or not, being able to operate from 50 to 60 Hz or 

vice versa. 

The equipment is set as frequency converters, so the static bypass 
and manual bypass are not available. 
So,  those  functions,  measurements,  alarm  messages,  parameter 
settings, as well as maneuvering of the relate

d switches will not be 

operative and they will not be taken into account.
