EA-ELR 10360-40 3U 5000W Programmable DC Load with Energy Recovery (EA-ELR 10000 3U Series)

The EA-ELR 10360-40 3U is a high-performance industrial 3U rack-mounted programmable DC load from EA Elektro-Automatik, belonging to the EA-ELR 10000 3U Series. It is designed for heavy-duty industrial applications, functioning as a 0-360V adjustable load and 0-40A variable current load with a rated power of 5000W. When operating on a 208V AC supply, it automatically switches to a derated mode, providing 3000W of available DC power to ensure safe and stable current draw.

Equipped with advanced energy recovery technology, the load achieves a high efficiency of up to 95.5%—it inverts consumed DC energy and feeds it back into the local mains, significantly reducing energy waste. As a low ripple 3U load, it delivers stable performance with voltage display accuracy ≤0.05% FS and current display accuracy ≤0.1% FS, making it suitable for sensitive testing scenarios. It supports four core operating modes: constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR), adapting to diverse industrial testing needs such as power supply validation and component performance evaluation.

The device features a switchable analog interface that supports 0-5V or 0-10V signal ranges for remote control, enabling seamless integration with external control systems like PLCs or PCs. It also supports ModBus RTU protocol via its rear USB port, facilitating digital communication and monitoring. Comprehensive protective functions are integrated, including overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), and overtemperature protection (OT), safeguarding both the load and connected equipment. For heat dissipation, it adopts forced air cooling with temperature-controlled fans (air inlet at the front, outlet at the rear) to maintain reliable operation in an ambient temperature range of 0°C (32°F) to 50°C (122°F).
