AC/DC Power Supplies             Try Our Power Supply Selection/Search Tool

AC/DC Power Supplies convert electrical power from one form to another and provide power to an electrical load. Astrodyne TDI offers top-quality solutions for AC and DC power supply in a variety of industries including: Industrial, Aerospace, Medical, and Military. Find units that generate as little power as 1W or more than 500kW — enough to power large industrial engines, machines and electric motors. We also offer different converters for each application including AC/DC, DC/DC, and PFC.

Types of AC/DC Power Supplies

Various configurations of Power Supplies within our inventory include:

  • Open Frame: This configuration exposes the supply's components to allow for superior cooling.
  • Enclosed: Enclosed power supplies protect components from the elements.
  • Encapsulated: Because these models don't feature any external components, they provide exceptional dust, moisture and vibration protection. We offer both PCB and Chassis Mount modules.
  • External: External power supply models, such as our external adapters and wall mount external adapters, are ideal for any application requiring an externally-located source of power and meet Energy Level VI standards.
  • Linear: Linear power supply models are suitable for low power applications and have very low noise/ripple.

You will also find several Power Solutions with capabilities over 1,000W, including:

  • Liquid Cooled: As the name implies, liquid cooled Power Supplies use water to cool down the system, resulting in immense power capabilities with little noise.
  • Air Cooled: Air cooled supplies use fans to cool the module. They offer high power capabilities and flexible input voltage ranges.
  • Outdoor Sealed: Our environmentally sealed power modules (ESPMs) are watertight and corrosion resistant for use in demanding applications.
