Supporting  system  designers  in  the

integration of the Excelsys power supplies into their system. 

Safety  and  Environmental  Certification:

All  our  power

supplies  carry  full  international  safety  agency  approvals
including UL and EN for information technology and medical
power  supplies.  To  ease  the  system  safety  approvals  we
have provided our UL and CB certificates and we have also
included our declarations of conformity. All Excelsys power
supplies are REACH and RoHS compliant. Visit our Safety
and Environmental section online where you can download

EMI  Characterisation: 

Excelsys  power  supplies  are

component power supplies and as such are not subject to the
EMC  directive  for  EMI,  however  in  order  to  ease  system
integration, Excelsys Technlogies has carried out extensive EMI
characterization of our products against the relevant standards. 

HALT (Highly Accelerated Life Testing):

Poor reliability, low

MTBF,  frequent  field  returns,  high  in-warranty  costs  and
customer  dissatisfaction  are  often  the  result  of  design  and/or
process weaknesses, even if a product has successfully passed
qualification tests and burn-in. Excelsys Technologies subjects
all our products to the HALT (Highly Accelerated Life Testing)
process to uncover design and/or process weaknesses. During
the  HALT  process,  the  product  is  subjected  to  progressively
higher stress levels brought on by thermal dwells, vibration, rapid
temperature transitions and combined environments.   

White  Papers

:  Excelsys  team  of  experienced  power  supply

designers  have  an  extensive  knowledge  of  power  supplies,
technology  and  the  challenges  facing  system  designers.  In
conjunction with the UltiMod Designers’ Manual, and Application
Notes, we also prepare White Papers on topics that are relevant
to system designers.  

Designers’  Manual: 

The  UltiMod  Designers’  Manual  has

been  prepared  to  assist  engineers  and  technicians  in
understanding correct design practices necessary to achieve
the  maximum  versatility  and  performance  from  any  of  the
UltiMod products. Whatever your application, be it industrial
electronics, medical equipment, automation equipment etc.,
the UltiMod Designers’ Manual provides the system designer
with  easy  to  implement  integration  instructions.  The
Designers’ Manual is available can be downloaded from the
Excelsys website.

Datasheets: 

There is an UltiMod for every application. Our

data sheets can be downloaded online.
