DG040 Series

DG040 Series

The DG040 Series is a small, open frame 40 watt power supply built with medical and IT equipment in mind. With a power density of 6.7W per cubic inch and running at greater than 84% electrical efficiency, the DG040 Series is Green Energy approved and designed for single output medical or IT applications. The universal input provides 90 to 264 volts of AC power while the compact 2” x 3” footprint makes it easy to integrate into printed circuit boards.

The DG040 is designed to operate at peak efficiency within a temperature range of 20°C (-4°F) and 50°C (122°F), and is rated to run at operating temperatures as high as 70°C (158°F). Safely store the DG040 in temperature conditions between -40°C to 85°C (-40°F - 185°F). Trust Tri-Mag to manufacture and supply safe, reliable power supply and electrical component solutions designed for the special needs and standards of medical, IT and telecom applications.

  1. Output Load: Convection cooling 40W.
  2. Peak Load Duration: 55W peak rating for durations up to 3 secs. (duty cycle < 10%, average power < 40W). Ideal for motor starting/in-rush conditions.
  3. Engineering Specification: Contact Tri-Mag for full engineering specification for the specific part number used in your design application.
  4. Standby Power Consumption with System: This is required by ENERGY STAR in U.S. and ErP regulation in Europe for appliances such as computers and displays. The latest requirement is measured input power to be less than 0.3W with system.
  5. Step Efficiency and Average Efficiency: Test conditions in step efficiency are referred to 3.2.2 IPS (Internal Power Supply) of the ENERGY STAR program requirements for computers. ENERGY STAR required for efficiency @ 20%, 50%, 100% load is 84.5%, 89%, 86.5%; average efficiency is the average of step efficiency.
