Powerbox launches ECDD DC/DC series for defense and harsh environments
News, Pressrelease
In modern defense and mobile platforms, system reliability is often determined by how well critical electronics perform under unstable power conditions. Ensuring continuous operation during electrical disturbances is essential for maintaining communication, navigation, and mission-critical functionality in the field.
Voltage drops during engine start, and load changes are a common cause of system reboot and instability in tactical and mobile platforms. Powerbox (PRBX), a Cosel Group company, addresses this challenge with the launch of its ECDD DC/DC power converter series, developed as an extension of its rugged defense power portfolio.
The ECDD series includes 250W (ECD250D) and 350W (ECD350D) models for 12V and 28V systems. Operating down to 11 VDC, the converters maintain continuous operation during voltage dips, preventing system resets and ensuring stable performance in critical applications. The units are designed to support MIL‑STD‑1275 D/E/F and MIL‑STD‑461G and are designed to meet CE and UKCA requirements.
Compliance with MIL‑STD‑1275 ensures reliable operation under vehicle power conditions, including voltage transients and cranking events, while MIL‑STD‑461G addresses electromagnetic compatibility in complex electronic environments. Together, these standards enable stable and predictable performance in electrically demanding applications.
Fully sealed in IP65-rated enclosures and utilizing baseplate conduction cooling, the ECDD series enables reliable, fanless operation in sealed environments where airflow is not feasible. The design eliminates moving parts, reducing both acoustic noise and failure risk, while delivering low-noise power.
The units are qualified to MIL‑STD‑810H for shock and vibration and provide low-noise power for sensitive electronics such as RF communication systems, mission displays, and surveillance equipment.
“The ECDD series is engineered to maintain stable output during voltage instability,” says Tetsuya Nagai, Vice President R&D and Products at Powerbox. “Its robust mechanical design makes it suitable for operation in harsh environments.”
While developed for defense applications, the ECDD platform is also well suited for emergency and service vehicles, mobile industrial equipment, autonomous systems, and sealed outdoor electronics where reliability under fluctuating power conditions is critical. The ECDD series is available for evaluation, with application-specific support.
