MIRA PRODUCT RANGE UPGRADES MoD VHEILCE ELECTRONICS
24 Jun 09. MIRA has developed a new range of power conditioners and EMC filters that enable military vehicles destined for current operational theatres to meet the latest MOD electrical & EMC standards.
A comprehensive range of power conditioners are now available with dedicated distribution points for a full suite of communication systems and electronic countermeasure equipment. The power conditioning units remove over voltage fluctuations and provide electronic circuit protection. Internal EMC filters protect the terminal equipment from vehicle generated RF disturbances, such as alternator whine and interference from systems like air-conditioning. EMC filtering between output terminals ensures the risk of intra-system interference is minimized.
If distribution within the vehicle platform is already designed, then a single high power conditioner unit introduced between the vehicle and terminal equipment distribution units eliminates any vehicle-borne voltage fluctuations and RF interference and will provide a Def-Stan 61-5 compliant power outlet.
In close support, MIRA’s range of EMC filters are designed to help vehicles achieve Def Stan 59-411 compliance, once distribution issues are resolved.
Peter Phillips, MIRA’s Electrical & EMC Engineering Manager gave his reaction: “We’ve worked fast to ensure that the widespread adoption of the latest regulations is supported by accredited service providers and products that make accreditation attainable. Our high current units are rated at over 100 Amps, so we can cover the most demanding applications. It’s not the first time we have led the world for Def Stan solutions, but it’s always satisfying to remain at the forefront – driving progress. These products complement our extensive accreditation for EMC approvals service for defence products.”
Recently Def Stan 61-5 & 59-411 were both updated to ensure that military vehicles posses a powerful yet robust electrical system that operates reliably in the arduous conditions faced by frontline troops. Def-Stan 59-411 relates specifically to the Electro-Magnetic Compatibility (EMC) performance of all new MoD hardware and the new Def Stan 61-5 issue 6 outlines the power distribution quality for all military platforms and sub-systems running up to 28V DC. Issue 6 renewed the MoD’s focus on the electrical systems in frontline vehicles, future proofing the fleet from the kind of issues raised by retrofitting modern systems into legacy equipment. The scope encompasses all new and existing vehicles destined for current operational theatres.
The MOD fleet contains an array of vehicle platforms developed over many years, which may utilise a power source dating back to the vehicle’s original design. The introduction of modern sensitive electronics presents an increasing level of risk to the quality and reliability of the vehicles electrical system. MIRA responded decisively to this challenge with the application of expert knowledge, to create this new product range that overcomes the technical issues faced when upgrading vehicles to the latest specifications.
