Captec developed an IEC 60945
certified rackmount dual-power electromagnetic interference (EMI) filter for commercial-grade servers in shipboard satellite communications. The design accommodated redundant power supplies, with more than 10,000 units supplied through worldwide distribution.
The customer is a global mobile satellite communications provider delivering connectivity services to customers worldwide. Its maritime services support communications aboard commercial ships, where onboard computing equipment must operate reliably alongside navigation, safety, and emergency communications systems in dynamic marine environments.

Enquiring about: Marine Certified Dual EMI Filter
The Challenges:
Enable commercial-grade Intel Xeon enterprise servers to meet the requirement of installation aboard commercial ships
Limit electromagnetic interference from computing equipment to protect emergency communication bands
Accommodate redundant server power supplies within a rackmount installation while meeting the required physical and electrical interfaces
Develop a dedicated filter because no suitable off-the-shelf product combined the necessary EMI performance, power arrangement and form factor
The Solution
Engineered an external rackmount EMI filter for commercial-grade IT hardware, including Dell XR2 servers
Integrated filtering to limit common-mode and differential-mode interference and reduce noise on the connected equipment’s power supply
Incorporated dual power connections to accommodate redundant server power supplies
Applied Captec’s Subsystems Engineering division to provide metalwork engineering and electro-mechanical integration delivery, as well as managing design, testing and production against IEC 60945 and DNVGL-CG-0339 requirements for marine applications
The Outcome
Achieved IEC 60945 certification for the EMI filter, supporting the customers shipboard satellite communications
Met the customer’s requirement for external EMI filtering while retaining the redundant power arrangement and rackmount packaging needed for onboard integration
Established a new product within Captec’s marine subsystems portfolio, with more than 10,000 units supplied through worldwide distribution beyond the initial customer-specific development
