Macroamp = High Quality = High Reliability

Our products are built to last and require very little maintenance. Founded in 1983, we have a very loyal customer following -- once a company has experienced our products they seldom go back to the products they had settled for in the past.

Trouble-free startup of full-load tested equipment is our guarantee.

We take a number of steps to ensure that our products are of the highest quality possible.

  • Conservative design philosophies ensure reliable performance and minimum maintenance for many years.

    •
  • The design and manufacturing of all major assemblies, transformers, rectifiers, and control systems are performed in-house.

    •
  • Only the highest-quality materials are used.

    •
  • Macroamp thoroughly tests all power supplies prior to shipment. Tight quality control and component compatibility is necessary to attain the high level of reliability that we are known for.

    •
  • Tolerances, fits, and techniques used in the finished products conform to the best modern shop and engineering standards.

    •
  • Our dedicated substation provides 5 MVA of energy for product testing. The power supply testing area has 2.5 MVA at voltages between 2.4 KV & 13.8 KV; and 1.5 MVA @ 480 VAC. Our variable resistance load bank has a range capacity up to 30,000 amperes. This allows dynamic, as well as static, testing at load voltages other than short circuit, assuring that operating and thermal characteristics are within design specifications.
