Power systems used in defense vehicles, mobile platforms and harsh industrial environments are rarely exposed to ideal operating conditions. Voltage dips, cranking events, electrical transients, vibration and thermal stress can all affect system stability and long-term reliability if not properly managed.
In these environments, power conversion becomes more than simply delivering output power. It becomes part of the overall operational reliability strategy.
Many modern vehicle and mobile systems are now designed with sealed enclosures, limited airflow and increasing onboard electronics, placing additional pressure on thermal management and long-term system availability. Traditional fan-cooled architectures are not always the most suitable option for these types of operating conditions, particularly where maintenance access is limited or continuous operation is critical.
PRBX Ruggedized Cooling & Enclosure Architectures
To address these environmental challenges, PRBX has developed a ruggedized portfolio of fan-free AC/DC and DC/DC power platforms engineered for harsh operating conditions. The portfolio covers three distinct design methodologies:
| Architecture Type | Environmental Suitability & Thermal Strategy |
|---|---|
| Open-Frame Systems | Designed for integration into existing customer enclosures where internal space optimization is critical. |
| Baseplate-Cooled Units | Utilizes conduction cooling to transfer heat directly to a cold plate or vehicle chassis, completely eliminating the need for fans. |
| Fully Sealed IP65 Solutions | Engineered for total protection against dust, water ingress, and harsh chemical exposure in external or unconditioned compartments. |
Regulated Output Solutions for 28V Mobile Platforms
Extending this ruggedized approach further, the recently launched ECD250D and ECD350D DC/DC series are designed for 28V vehicle and mobile platforms operating under unstable electrical conditions. The sealed fan-free platform is engineered to maintain stable regulated output during voltage dips and transient disturbances commonly found in harsh mobile environments.
Together, the PRBX ruggedized AC/DC and DC/DC portfolio supports engineers developing reliable systems for applications including defense vehicles, radar, communications, surveillance, industrial automation and other demanding field-deployed platforms.
