EA-PUL 10750-240 6U WC Programmable Electronic DC Load with Energy Recovery

The EA-PUL 10750-240 6U WC is a high-performance, regenerative, and programmable DC electronic load unit capable of operating as a bidirectional DC power supply in sink mode. With its 60 kW power rating, it features a wide DC input range of 0–750 V and 0–240 A, utilizing autoranging technology to maintain full power across its operational envelope. This water-cooled (WC) version ensures efficient thermal management, making it ideal for continuous high-power testing applications. The unit boasts energy recovery capabilities, feeding up to 96.5% of consumed DC energy back into the AC grid, significantly reducing operational costs and thermal footprint. It supports multiple regulation modes (CV, CC, CP, CR) with fast crossover, offers galvanically isolated interfaces (USB, Ethernet, analog), and can be paralleled with up to 63 additional units via the built-in Master-Slave and Share-Bus systems for systems up to 3840 kW. Designed for demanding applications such as battery testing (including State of Health and End-of-Line tests), fuel cell testing, on-board charger validation, and battery recycling systems.
