EACR series: Combined ground power units for Aircraft (400Hz + 28V DC)
ElectroAir EACR combined power supply units
ElectroAir’s EACR series delivers a compact, efficient solution for modern ground support – combining both 400 Hz AC and 28.5 V DC power in a single unit. Engineered for flexible deployment and seamless integration, these combined power units are ideal for apron operations, hangars, or passenger boarding bridge zones.
Overview
Modern airports face growing pressure to optimize ground operations, reduce energy consumption, and streamline equipment layouts, all while supporting a wide variety of aircraft types. ElectroAir’s EACR series is designed to meet these challenges head-on by combining two essential power formats – 400Hz AC and 28.5V DC, into a single, compact ground power unit. Traditionally, airports rely on separate equipment to supply AC and DC ground power, resulting in increased space usage, complex cabling, and higher maintenance costs. With the EACR series, ElectroAir eliminates the need for multiple devices by offering a fully integrated solution that saves space, simplifies logistics, and improves energy efficiency.
Available in various power ratings, EACR units are suitable for a wide range of aircraft, from narrow-body commercial jets and regional planes to wide-body aircraft and even military applications. The series includes stationary (STD) and mobile (M) versions, allowing for flexible installation on the apron, in hangars, or beneath passenger boarding bridges. Designed for continuous operation in demanding environments, all EACR units are built with rugged enclosures, industrial-grade components, and user-friendly control interfaces. Remote monitoring and Ethernet integration ensure that these units can easily be incorporated into smart airport infrastructure and centralized GSE management systems.
From new airport developments to retrofit projects, ElectroAir’s EACR series offers a future-proof investment for any operation seeking to reduce costs, improve turnaround times, and meet modern environmental standards – without compromising on power availability or equipment performance.

Why choose EACR combined units?
Airports today are expected to deliver fast turnaround times, optimize space usage, and meet sustainability targets, all while ensuring uninterrupted service for a wide variety of aircraft. ElectroAir’s EACR series responds to these demands by offering an all-in-one ground power solution that is not only compact and powerful but also smart, adaptable, and future-ready. By combining 400Hz AC and 28.5V DC power outputs into a single unit, EACR eliminates the need for separate systems, extra cabling, and redundant infrastructure. This reduces installation complexity, minimizes footprint, and lowers operational costs, especially in high-traffic areas such as boarding bridges, aprons, and MRO zones. ElectroAir engineers each EACR unit for real-world durability, including full functionality across extreme temperatures, heavy-duty cycles, and harsh environments. Units feature modular construction, enabling simplified maintenance and fast part replacement, and are equipped with digital interfaces, smart protections, and remote diagnostics.
Whether you operate a small regional airfield or a major international hub, EACR units help you:
🔧 Simplify GSE infrastructure with fewer devices per gate
🌍 Reduce emissions by replacing multiple diesel-powered units
💡 Streamline maintenance through shared parts and modular design
📊 Integrate easily with centralized airport systems via Ethernet or wireless
🔋 Improve energy efficiency with high-performance conversion modules
EACR units are also ideal for hybrid configurations, including integration with PCA systems, bridge-mounted enclosures, or underground pit systems – offering full flexibility in how and where power is delivered. From budget-conscious regional airports to large-scale greenfield projects, choosing EACR means investing in long-term reliability, operational efficiency, and smart airport readiness.
