High  efficiency  cost  effective  power  supply  suitable  for  use  in  systems  designed  to  comply  with 
PD6662:2017 and EN50131-6:2017 Grade 3 and Environmental Class II. Rated to provide 

continuous 

current to load

 for systems requiring 12h standby from a battery. Three independent output signals 

are  provided  for  loss  of  mains  fault  (EPS**),  battery  fault  (APS**),  and  power  supply  fault  (GEN). 
Comprehensive  self-diagnostics  can  detect  blown  output  and  battery  fuses,  battery  fail,  low  battery 
voltage,  battery  missing  and  low  output  voltage.  The  PSU  incorporates  intelligent  battery 
management  comprising  active  full  load  battery  testing,  low  battery  voltage  detection  and  deep 
discharge  protection  to  ensure  that  the  battery  is  not  permanently  damaged  through  excessive 
discharge. A brownout filter ensures that short mains voltage dips do not create a false loss of mains 
alarm. Two LEDs assist with quick and easy installation by showing presence of mains, correct battery 
charging  or  a  fault  condition.  Comprehensive  protection  is  built-in  as  standard  including  mains 
transient filtering, electronic output overload protection and fuses on the load and battery outputs.
