Advanced Energy's DF150 Is a 160W Power Supply Built to Survive Arctic Cold and Combat Vibration
Advanced Energy has launched the DF150, a ruggedized 160W AC-DC power supply aimed at engineers and procurement teams in defense, telecommunications, transport, and energy. It's the first product in the company's new Defiant Future series, and it's built to the kind of spec that standard commercial hardware simply can't meet. For defense contractors looking to cut validation timelines, a pre-certified commercial off-the-shelf (COTS) unit like this is a meaningful shortcut.
The spec
The DF150 outputs 27 VDC at up to 6 A for a maximum of 160W, with 91% efficiency at full load — a strong figure for the AC-DC segment, which accounts for over 62% of the power supply market. Leakage current at 230V sits at 275 µA.
The unit is certified to MIL-STD-810H, covering shock, vibration, altitude, and temperature extremes. Operating range is –46°C to +60°C with no claimed performance drop across the full span — relevant for anything deployed in arctic environments or inside high-heat enclosures. An IP67 rating adds dust and water resistance.
Electromagnetic compatibility is handled by MIL-STD-461G certification, verified across eight test categories including RE102, CE102, CS101, CS114, CS115, CS116, CS118, and RS103, as confirmed by Interesting Engineering. That matters in dense telecom platforms where dozens of sensors and transmitters share a single enclosure — interference from the power supply itself can degrade the whole system.
Two cooling configurations are available: conduction cooling through the unit's base plate, or a heatsink with natural convection. Input cable configurations and housing finishes can be specified at order.
The market
Advanced Energy VP Joe Voyles described the DF150 as combining the reliability of specialized military supplies with the accessibility of commercial products. The pitch is speed-to-deployment: custom military power supplies require long lead times and independent validation; a COTS unit with dual MIL-STD certifications already in hand reduces that burden for contractors.
At 160W, the DF150 isn't powering a command center. It's sized for embedded subsystems — sensors, modems, communications modules — inside larger platforms. Per MarkWide Research, the North American rugged power supply market was valued at $0.95 billion in 2023 and is projected to reach $1.75 billion by 2032, with the military segment growing at a 5.4% CAGR. The efficiency gains here are worth comparing to what's happening in consumer charging too — the gap between GaN vs Silicon Chargers: Why Your Next Brick Should Be GaN shows how much headroom modern power conversion still has.
No pricing or US retail availability has been announced. Advanced Energy (Nasdaq: AEIS) sells through industrial and defense distribution channels, not consumer electronics retail.
