Advanced Energy DF150, 160 W Ruggedized AC/DC Power Supply with Full MIL-STD-810H and MIL-STD-461G Certification
Comprehensive Military-Standard Compliance in a Standard Commercial Product
Procurement of ruggedised power supplies for defence and critical infrastructure applications has historically required a choice between two unsatisfactory options: custom or semi-custom power designs with long lead times and high non-recurring engineering costs, or standard commercial products that lack the environmental qualification and EMC compliance that the application demands.
The Advanced Energy DF150, part of the Defiant Future™ series, addresses this directly. It is a 160 W, fully enclosed, fanless AC/DC power supply delivering 27 V DC at 5.93 A, certified to both MIL-STD-810H for environmental durability and MIL-STD-461G for EMI/EMC compliance. It is a standard, commercially available product; available from stock, scalable to high-volume production, and carrying the full certification documentation required for defence and critical infrastructure procurement.
FORTEC Switzerland offers the DF150 as part of its Advanced Energy portfolio.
MIL-STD-810H and MIL-STD-461G, Full Certification, Not Compliance Claims
The DF150 carries full tested and certified compliance to the two military standards most frequently specified in defence power supply procurement:
MIL-STD-810H covers the complete set of environmental durability conditions that ground-deployed equipment must withstand: altitude, humidity, temperature extremes (-46 °C to +60 °C operating range), mechanical shock, and vibration. These tests establish that the DF150 performs reliably through the conditions encountered in operational deployment rather than only in controlled laboratory environments.
MIL-STD-461G governs the electromagnetic interference and compatibility requirements for defence equipment. Compliance ensures that the DF150 neither radiates interference that could affect co-located electronic systems nor is disrupted by the electromagnetic environment it operates within.
Beyond these standards, the IP67 rating means the enclosure is completely sealed against dust ingress and supports full submersion in water to a depth of 1 metre for up to 30 minutes, exceeding MIL-STD requirements for dust and ingress protection. This level of sealing makes the DF150 directly suitable for deployment in exposed or wet operating environments without additional enclosure protection.
Fanless Design with Convection or Conduction Cooling Options
The DF150 operates without a fan, eliminating the most common mechanical failure point and enabling silent operation; a relevant consideration for applications where acoustic signature must be controlled. Two cooling paths are supported: natural convection for installations where heat dissipation through the ambient air is sufficient, and conduction cooling for sealed or high-density enclosures where heat must be transferred through the chassis.
This dual cooling flexibility allows the same DF150 to be specified across a range of installation architectures without requiring a different product variant for each thermal configuration.

From Standard Product to High-Volume Delivery
One of the practical advantages of the DF150 is its status as a standard commercial product. Unlike custom-designed military power supplies, it is available from stock for immediate procurement, fully documented with traceable certification records, and supported by Advanced Energy's established manufacturing infrastructure for rapid scaling to high-volume production quantities. This combination reduces both procurement lead time and programme risk for projects requiring fast deployment.
Target Applications
The DF150 is engineered for demanding applications across:
- Defence and security ground equipment
- Military communication and data processing systems
- Industrial automation in harsh or outdoor environments
- Telecommunications infrastructure in exposed installations
- Transportation and rail systems
- Energy and utility infrastructure in extreme climates
