Description
Overview
The EA Elektro-Automatik EA-PSB 10500-20 2U is a compact rackmount bidirectional DC power supply capable of operating as both a power source and an electronic load. With 500V/20A/3000W output capability and input voltage range of 110-240V single-phase AC, it is well-suited for laboratory and portable testing applications. In load mode, the unit regenerates energy back to the AC mains grid at efficiencies exceeding 96%, significantly reducing operational costs while minimizing heat generation.
The supply features advanced digital regulation with 16-bit resolution, a 5-inch color touchscreen display, and comprehensive simulation capabilities including battery, fuel cell, and photovoltaic test modes. Its flexible autoranging output stage delivers constant voltage, current, power, or resistance modes with fast crossover switching, making it adaptable to diverse testing scenarios.
