Ground power unit load bank EAL-400

The EAL-400 is a compact and portable AC load bank designed for accurate simulation of 400Hz ground power conditions. Built for use in maintenance facilities and on-site operations, this unit provides a reliable and efficient method for testing, calibrating, and adjusting aircraft Ground Power Units (GPUs) without needing to connect directly to the aircraft. By simulating real operational loads, the EAL-400 helps technicians validate GPU performance under stress, verify repair quality, and conduct routine diagnostics safely and independently. Featuring durable construction and user-friendly controls, the EAL-400 can be used in both workshop and field environments. It enables engine start simulations and supports scheduled GPU performance verification to prevent future failures. The device is fully compatible with ElectroAir and third-party 400Hz systems and offers high power precision without compromising portability. Whether supporting commercial airlines, MRO operations, or military fleets, the EAL-400 ensures your 400Hz GPUs operate at peak reliability and meet all industry requirements. Minimize aircraft downtime, reduce risk of power-related faults, and extend GPU lifespan - all with a single robust testing tool.
