 We Turn Military Power Conversion Requirements Into Reality


Challenge our innovative design engineers to develop the exact military power supply solution - for any requirements - which best meets your application needs. Areas of military power supply design expertise include: Extreme EMI / Reliability / Thermal Management / High Power Factor / Shock and Vibe / Power Density. The following are just a few of our previous custom military power supply design examples.   

Examples Custom Power Supplies Design by Milpower Source 





A custom design Cabin Power Supply Model (CPSM), designed for an airborne radar application featuring liquid cooling.  





Modified VPX VITA 62 DC/DC Power Supply for an airborne application. Custom engineered to include floating connectors, modified form factor, modified heat dissipation and Alternative AC input capability. 






Featuring two split DC outputs, with same output voltage, and AC/DC input capabilities this unit was custom designed for a ground defense application.  

Generator Control Unit




Generator Control Unit (GCU) designed for a rotorcraft application, this Generator Control Unit (GCU) provided the client with the required multi-output design and MIL-Standard qualifications required.







Designed for a missile application, our engineering team successfully addressed the MIL-STD-810g Shock and Vibration requirements, while delivering a custom form factor DC/DC converter unit which met all of the other requirements the customer presented.





Designed as a standalone, high power factor, natural convection cooled converter this unit is deployed by multiple branches of the military, in all environments.  




M259 TRU

Designed for an airborne application, this Transformer-Rectifier Unit (TRU) is MIL-STD-704A, MIL-STD-461E compliant and features up to 18kW load, delivers over 95% efficiency and low input THDI – below 8%




A naturally convection converter designed to MIL-STD-1275B, with 24 outputs, up to 1.8kW continuous no derating at -30°C to +55°C ambient.

Pulsed Load Attenuator



Designed for a ground radar application, the Pulse Load Attenuator feeds a single PA, is sequenced (50V turns on 0.7s after other voltages) and hold up full power 3ms on input failure.    






A 288-350VDC Filter and Control Unit (FCU), wiht 7 outputs, over load disconnection and filtering 

M793 DC-DC Converter


In use aboard hundreds of commercial jets, the high-density 6.6KW DC/DC converter was custom designed as a starter power unit. One of the special features includes thermal sensor baseplate temperature monitoring.
