Power
A full line of Commercial Off-the-Shelf (COTS), Modified COTS and Custom Power Supplies – including configurations that meet VME, cPCI and VPX (VITA 62) requirements. All comply with environmental standards designed for harsh environments.
Specifically designed for rugged defence, industrial, and commercial applications operating in extreme conditions, these high-density power supplies provide significant cost benefits and deliver COTS solutions that accelerate deployment of SWaP-optimised systems in air, land, and sea systems. Available form factors include 3U, 6U, Brick and Standalone units, from NAI & Dawn.
Complete vehicle battery and power management systems for military and blue light applications from Merlin.
3U POWER SUPPLY
COTS and Modified COTS power supplies and power converters that plug directly into standard 3U chassis and are conduction-cooled at the card edge/wedgelock interface.
Choose from Three Product Families:
• DC/DC VITA 62 VPX Power Supplies
• DC/DC Holdup & Power Conditioning Units
• AC/DC VITA 62 VPX Power Supplies
With their advanced design, these rugged power supply units accept either +28 VDC input, +270 VDC input or 3Ø AC input. DC/DC Holdup & Power Conditioning units are available to accept +28 VDC input or back end +12 VDC input. These off-the-shelf solutions for VITA 46.0 and VITA 65 systems are compatible with VPX specifications; support all VITA standard I/O, signals, and features; and conform to the VITA 62 mechanical and electrical requirements for modular power supplies.

BRICKS
Small footprint power supply bricks; available in configurations of up to 3 outputs, with output power up to 500 Watts. These accept AC, +28 VDC or +270 VDC Inputs.
Example: 25-Watt DC/DC Converter – 55GS1
NAI’s 55GS1 is a COTS, 25-Watt DC/DC Converter that accepts a +28 VDC input and provides a single full-power output at a baseplate temperature of +100°C.
Standard features include remote error sensing; remote digital (TTL) turn on/off; and protection against transients, overvoltage, overcurrent, and short-circuits. Options such as ESS vibration testing and choice of output voltages are available, and additional options and special units can be ordered.
This conduction-cooled, switching power supply is specifically designed with NAVMAT component derating for rugged defense and industrial applications. It is also designed to meet the many harsh environmental requirements of military applications.
STAND ALONE UNITS
NAI’s AC/DC standalone EMI compliant power supplies accept a 3Ø AC input as well as a +270 Volt DC input and are available in a single output with operating power of 2,000 Watts. All units are specified over their full operating temperature range at full-load conditions. These rugged units are baseplate conduction-cooled and are specifically designed with NAVMAT component derating for rugged defence and industrial applications. These power supplies have integrated, standalone compliant EMI filters per MIL-STD-461.
Standard Features:
• Input Transient Protection Per MIL-STD-704F
• Integrated EMI filtering & compliance per MIL-STD-461 (CE102, CS101, CS114, CS115, CS116, RE102, RS103)
• Environmental compliance per MIL-STD-810G & DO-160G
• Over-Temperature Warning & Shutdown
• Continuous Background Built-In-Test (BIT)
• Current Share with monitoring
• Remote Error Sensing
Complete battery and power management systems.
The Merlin battery monitoring systems give you high accuracy State of Charge (SoC) and State of Health (SoH). This tells you how much juice you have in your system and how long your batteries have to go before you need to change them out. Leveraging on this core function Merlin provide additional equipment and expertise to allow users to build complete battery and power management systems onto vehicles.
Defence: Power is the greatest enabler for the war fighter. It is also the greatest limitation. Merlin are experts in the provision of power for land platforms. These products are fitted on Main Battle Tanks through to Walk On Fit equipment. These systems are recognised by DSTL, TARDEC and armies around the world as being the most reliable, efficient and effective systems available.
