EA-PUL 12000-80 6U WC Programmable Electronic DC Load with Energy Recovery

The EA-PUL 12000-80 6U WC is a high-power, 60 kW programmable electronic DC load unit featuring advanced energy recovery technology. As a bidirectional power supply, it regeneratively feeds up to 96% of the absorbed DC energy back into the AC grid, drastically reducing operating costs and thermal load. Designed for demanding applications like battery and fuel cell testing, it offers a wide DC input range of 0 to 2000 V and 0 to 80 A, operating on a constant power (autoranging) curve. This water-cooled (WC) version ensures efficient thermal management in high-density or continuous operation setups. With integrated Master-Slave and Share-Bus, up to 64 units can be paralleled to create systems up to 3840 kW, behaving as a single, cohesive unit. It comes with galvanically isolated interfaces (USB, Ethernet, Analog) and supports numerous optional industrial communication protocols, making it a versatile and scalable solution for laboratory and industrial power testing.
