  • Polyamp has always taken great environmental responsibility, through active participation in groups, committees and inquiries relating to environmental matters. We have always been at the forefront concerning environmental activities.
  • In addition to these environmental requirements, we strive to reduce the environmental impact throughout the entire product lifecycle; from the initial stage of a product to its end-of-life.
  • Polyamp is working with an environmental program to minimize the use of hazardous materials and to reduce production time.
  • Our choice of design and component selection means that even a 40-year-old Polyamp product is easy to recycle.
  • Packaging material is designed with concern for environmental aspects.
  • More information is available on our environmental web pages.

Open/Closed Company

  • Polyamp is an open company and we are happy to work with companies / schools / organizations. We are happy to share our long experience.
  • At the same time, we produce military products for customers under certain restrictions, depending on different requirements.

Collaboration with Universities

  • Polyamp has for years enjoyed beneficial collaborations with KTH Royal Institute of Technology Stockholm and Linköping University to improve the quality of both our products and organization. Through partnerships with colleges and universities Polyamp exchanges knowledge with competent and independent experts. This promotes a holistic awareness and strengthens Polyamp's competitiveness.



  • Most Polyamp PSU formerly used air cooling or conduction cooling. To achieve a low average temperature providing long life expectancy, we now use a more expensive aluminum casing for the unit. It also provides excellent mechanical, environmental, EMC and fire properties.
  • Polyamp has always used robust aluminum profile case. The reason was that Polyamp's founder already in the 1960's had the notion that aluminum has a good heat transfer through the material but not along the surface. To achieve that, you need more material to spread the heat.
  • Secondly the surface color does not matter for the cooling effect, therefore Polyamp profiles where greenish until the '80s when this "Polyamp Green" became obsolete. At that time, we changed to the current gold/yellow color. This color does not add to the cost of the case.
  • We have replaced surface increasing methods after realizing it's better to have a flat surface and increase the thickness to spread the heat, and add more aluminum for better cooling.
  • While aluminum is expensive to produce as a raw material, it is easy to recycle. Today our cases contain 70% recycled aluminum and our design makes the profiles easy to recycle.

5 min installations

  • The units are supplied with different attachment methods depending on the model such as: wall mounting, DIN rail, 19"-subrack module or 19"-modular. The units have no ventilation holes to prevent dust from entering the interior portion, which is important for industrial and mobile applications. All models are convection-cooled (except PC1400 & PC2000) and require no special installation or additional cooling. The units can be mounted in any direction.


  • Our internal design requirements are tough in order to meet industry standards. That's because the same product must meet multiple applications with different requirements.
  • We have extensive experience and can guide the customer regarding what their applications require.


  • All products are CE marked, for electrical safety, EMC and RoHS directives.

Galvanic separation

  • All Polyamp DC/DC converters are galvanically isolated between input / output and input / output to chassis.


  • Usually, there is much "dirt" in all electrical wires. Polyamp sets the bar high to improve this as much as possible.
  • We have filters on the input AND output, which produces a much cleaner output current compared to what other manufacturers can offer.
  • Also see our FAQ.


  • EMC is the scourge of modern life since it creates an elusive problem. Polyamp has long taken these problems 100% seriously. We build our equipment for maximum interference protection.
  • Also see our FAQ.


  • We manufacture DC-DC converters for specific customer needs.
  • We try wherever possible to modify standard equipment within the confines of the CE marking.

Quality system

  • Polyamp is ISO9001:2008 certified and has had system in place since 1993. We have worked with Lean methods since 1998. We also have an extension for Nuclear Power plant 1E. Open our ISO9001:2008 Certificate.

Support system

  • Electronics production involves complex logistics since each product contains hundreds of components and if even one is missing a product cannot be built.
  • Since 1983, Polyamp's computerized support system has helped us to provide fast and accurate delivery information. Every year we are very close to 98% on date delivery.

Mine Protection
