The device series from EA Elektro-Automatik ELR 10000 are programmable electronic loads. The device is regenerative and feeds the energy back into the local grid with an efficiency up to over 96%. The ELR 10000 series includes single and three phase units, which, together with the wide input range, allows use with practically all global mains voltages. The DC voltage and current are directed by the application and the spectrum ranges from 0 - 80 V to 0 - 2000 V and from 0 - 6 A up to 0 - 1000 A in a single device.The DC-Input operates as a flexible input stage with a constant power characteristic (autoranging), and a wide voltage, current and power range. To achieve higher power and current all units are equipped with a master-slave bus. This enables up to 64 parallel connected devices to be combined into one system which can provide a load up to 1920 W and 64000 A. Such a system works as a single unit and can use different power classes, only the voltage class must remain constant. In this way a user can construct a 75 kW system from two 30 kW and one 15 kW devices from the ELR 10000 range. Furthermore, typical laboratory functionality is provided. This includes an estensive function generator, alarm and warning management, assorted interfaces and ports, software solutions and many more functions.

AC Connection
The electronic loads in the ELR 10000 series are equipped with an active PFC which provides a high efficiency at a low energy consumption. Furthermore, the devices in this series provide a wide input voltage range. It reaches from 110/120 V up to 240 V with 1-phase models and from 208 V to 380/400/480 V with 3-phase models. Hence the devices can be operated in the majority of global grids. They adjust automatically, without additional configuration, to the available grid voltage by applying a derating of the DC input power. The separately available US208V models, however, provide the full rated power at a supply with 208 V.

Energy recovering
The energy consumed in load mode is fed back into the connected mains supply with an efficiency of over 96%. This reduces cost: as the energy is not converted to heat as in other loads, the energy costs are reduced. In addition, the devices generate less heat requiring less cost intensive air conditioning. One device is sufficient for the whole application, reducing investment and installation costs.
