MILITARY-GRADE POWER SOLUTIONS

For Seaworthy Applications

The demanding conditions encountered at sea place a number of limitations on the power supply. Naval ships, subs, and amphibious vehicles rely on electronics to power navigation systems, communication equipment, weapon systems, and other critical operating gear. This equipment must operate properly in challenging shipboard conditions, such as high humidity and unstable environments. At Advanced Conversion Technology (ACT), we understand the need for precision-engineered power solutions that meet the unique requirements of the Naval industry.

Types of Shipboard Power Supplies

Marine-ready, military-grade power supplies must supply steady and dependable power despite the harsh conditions encountered at sea. At ACT, we specialize in military AC-DC power supplies for all environments and manufacture many products compliant with MIL-STD-1399, Section 300.

What is MIL-STD-1399 Section 300?

MIL-STD-1399 Section 300 defines the characteristics of low voltage shipboard electric power systems at the interface connection and provides the constraints on the power source, the distribution system, and the user equipment for both the design and operation. For military vessels, the policies and procedures are mandatory for engineers and project managers to consider.

Shipboard Power Products from ACT

The harsh conditions encountered at sea demand rugged and reliable power supplies. At Advanced Conversion Technology (ACT), we manufacture a comprehensive lineup of military AC-DC power supply systems for use in Naval and other seaworthy applications. Our products can be found powering satellite equipment, navigation systems, and other critical components on submarines, Navy ships, and more. To support several potential applications, we offer:

  • 115 VAC, 3-phase and single-phase ungrounded power supply systems
  • 440 VAC, 3-phase and single-phase military power supply systems
  • 60 or 400 Hz power supply systems
  • Active power factor corrected power supply systems
  • Many secondary voltage configurations

Our products are available in ruggedized housings for superior protection against moisture, salt, vibration, shock, and other common shipboard hazards.

No matter what your application demands, we can help. Our premier, custom power solutions also meet the needs for reliably powering this demanding domain in the following ways:

  • MIL-STD-1399-300-1 Compliance: MIL-STD-1399 outlines user equipment interface requirements and provides test requirements for AC-DC shipboard military power supply systems. Some of these include grounding susceptibility, power profile test, voltage spike susceptibility, and simulated human body impedance ground current test. ACT provides custom MIL-STD-1399-compliant power supply units for support vessels, research ships, aircraft carriers, submarines, and other Navy ships. These seaworthy power supply units are designed to ensure exceptional quality in all marine environments.
  • High-Impact Shock Standards: Marine environments pose unique shock challenges, and ship military-grade power supplies must comply with strict standards. ACT can design and test custom shipboard power supplies to MIL-DTL-901, MIL-STD-202, or MIL-STD-810 depending on your requirements.
  • Vibration Standards: Any equipment installed on a military marine vessel has unique vibrations that it must withstand. This is true for ACT power supplies. They can be designed and tested to meet the standards found in MIL-STD-167-1A for mechanical vibrations and tested to meet NAVMAT P-9492 for random vibrations and MIL-STD-202, Method 201 for sinusoidal vibrations and/or MIL-STD-810.

Powerful Solutions

Looking for a power solution to quickly meet your program schedule? Our AC-DC MIL-COTS are ready-to-ship and ruggedized for life at sea.

  • These power supplies still meet MIL-STD-1399-300-1.
  • They are tested during the prototype phase for compliance with MIL-STD-202 Method 213, Test Condition for shock, and are designed to meet the high-impact shock tests of MIL-DTL-901.
  • They are also designed to meet the standards found in MIL-STD-167-1A for mechanical vibrations and are tested to meet NAVMAT P-9492 for random vibrations and MIL-STD-202 Method 201 for sinusoidal vibrations during the prototype phase.
