Who are we ??

 
  Based in Peterborough in the UK we are a team of highly experienced industry trained ex - Ferrus Power
  engineers with an established foundation in the field of SMPS ( switched mode power supply ) test and 
  service. Whilst we offer a repair and refurbishment service for all brands of both switchmode and linear
  power supplies, due to our background, we particularly specialise in the range manufactured by Ferrus
  Power.

  We have an extensive working knowledge of all known power supply operating topologies from simple shunt
  regulator linear power supplies to the latest SMPS products including active power factor correction
  circuitry.

  The primary mode of failure within any power supply is due to electrolytic capacitors, which can then result
  in catastrophic semiconductor failure. As part of the service process we check the condition (via ESR) of all
  capacitors within a product and replace where necessary using only reputable brands rated to 105 Deg C.

  After servicing, using specialist electronic loads within our service department, we are able to fully retest
  your power supply to the original safety standards as when first manufactured.

  Testing includes :

• Output Load regulation
  (including dynamic load testing where required)
• Input Line regulation
• PFC operation and boost HT voltage check
• Output ripple and noise (RMS and Pk-Pk to 30MHz)
• Overvoltage and overcurrent protection checks
• Ancilliary alarm signals (such as mains powerfail/DC ok etc)
• Control inputs including remote sense/inhibit functions
• Current share operation where applicable
• Fan operation where applicable
• Safety (HI-POT) insulation checks - details here
• Soak test (@ 50% load minimum for 3 hrs) - details here

Due to our contact base we have at our disposal a vast range of stocked components as commonly used within the power supply industry. This stock enables us to offer both a faster turnaround of repair as well as a reduced cost for replacement components (which is subsequently passed on to our customers).

We aim to return your product so as to offer the highest degree of future reliability possible with the confidence in the level of our servicing such that we offer a 12 month warranty as standard.

     If you are experiencing reliability issues with a product we offer a full product analysis service
                 with detailed report - see our Analysis section for more details and report example.
