Ground Vehicle Power Supply

Industry Profile: Ground Transportation

Ground Vehicle Power Supply

Advanced Conversion Technology (ACT) is proud to be an emerging leader in the field of ground vehicle power supply. Though our focus has historically been on aerospace and shipboard electronics, we have started applying our expertise to the development of power supplies for ground vehicles that conform to MIL-STD-1275 standards.

With advanced, vertically-integrated manufacturing capabilities and over 40 years of engineering expertise, we’ll develop low-cost, off-the-shelf solutions for delivering reliable power in tanks, mine rollers and other military ground vehicles as well as various ground equipment

Our Facility

Our 63,000 square foot, vertically-integrated facility in Middletown, PA is the key to our advanced production capabilities. From there, we can control all aspects of the production and development cycles, resulting in a final product that is cheaper, faster to produce, and subject to higher levels of quality control than power supplies manufactured overseas. Vertical integration also gives us greater flexibility to accommodate rush or custom orders, as we can prioritize production requirements more effectively.

Our quality system is certified to AS9100 and ISO9001:2015. A full-time inspection team performs multiple QC checks on each piece of hardware we deliver, ensuring we meet the demanding requirements of our defense industry customers.

Ground Vehicle Power Supply

Developing reliable power supplies for military ground vehicles and equipment presents various challenges that require precision-engineered solutions. Unlike air or naval platforms, ground vehicles are frequently deployed in dusty, humid or sandy conditions — anticipating these environmental concerns is essential in the design of any power supply. Hardware must also be able to withstand the bumps and shocks associated with travel in rough terrain.

At ACT, our ground vehicle power supply products can be mounted in a ruggedized frame to protect them from damage. We also offer hermetically-sealed modules that keep out dust particles and keep your equipment safe at any temperature or humidity level.

Types of Ground Vehicle Power Supplies

In the most demanding military applications, reliable power is a necessity. Advanced Conversion Technology (ACT) specializes in sophisticated technical solutions that can handle the input requirements defined by MIL-STD-1275, hence calling it a MIL-STD-1275 power supply. With more than 30 years of expertise, we are the first choice of military contractors and high-end industrial manufacturers across the country.

Meeting MIL-STD-1275 Power Supply Requirements

MIL-STD-1275 power supply standards outline requirements for any military ground vehicle power supply. They can also be useful to civilian manufacturers of off-road vehicles and heavy equipment. Military vehicles employ a nominal 28 V power supply system and much of MIL-STD-1275 requires ensuring these systems are able to handle transient spikes and surges.

According to MIL-STD-1275, ground vehicle power supplies must be able to handle:

  • Transient spikes of up to ±250 V for 50 µs with durations no longer than 1 ms with maximum energy of 15 mJ

The surge info is as follows:

  • Surges of 100V
    • Surge for 50 msec without degradation
    • Five (5) pulses total, with five (5) seconds between pulses
    • Continually provide regulated output

According to MIL-STD-1275, the impedance level is 500 mohm.

Our Products

ACT offers both off-the-shelf-like and modifiable MIL-STD-1275-compliant power supplies for military ground vehicles. Our products include AC-DC and DC-DC power supplies with multiple outputs, EMI shielding, and other advanced features that make them ideal for powering communications, engine control, guidance and other sensitive systems. Key features of our products include:

humvee power supply

  • Short circuit, reverse polarity and overload protection
  • High reliability for use in the most demanding applications
  • Superior EMI/RFI control and management
  • Remote on/off control
  • Many additional features

Our forced air and natural convection-cooled products can be utilized in temperatures ranging from -40 to 71°C. Rugged housings and complex packaging options further add to the versatility of our ground vehicle power supplies. Outside of military use, our products are ideal for any application in which resistance to vibration, shock and other environmental/physical stresses is required.

No matter what the specific needs of your project are, ACT can accommodate them. Contact our office directly to ask about application-specific designs and other product development services. Since 1981, we have been an important ally to America’s defense contractors. With our recent move into the development of ground vehicle power supply systems, even more customers can benefit from our engineering expertise.

The Industry Leader in Ground Vehicle Power Supplies

If you need a reliable power supply, contact Advanced Conversion Technology first. Our products are simple, stress-resistant and fully compliant with MIL-STD-1275 and related standards such as MIL-STD-461, MIL-STD-810 and MIL-STD-202. Our 63,000-square-foot domestic manufacturing facility is vertically integrated, meaning all fabrication and acceptance testing is done in-house. This allows us to maintain an exceptionally high level of quality control when producing ground vehicle power supplies for military and civilian use. We can quickly turn around any order at a price that works for your budget.
