Description
The device series ELR 10000 from EA Elektro-Automatik are programmable electronic loads. The devices are regen-erative and feed the consumed DC energy back into the lo-cal or public grid with an efficiency of up to 96%. The series offers single-phase and three-phase models which, togeth-er with the wide input range, allow operation on practically all global mains voltages. The rated DC voltages and cur-rents are determined by typical applications and the spec-trum 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 characteris-tic (autoranging) and a wide voltage and current range. To achieve higher powers and currents all units are equipped with a master-slave bus. This allows for up to 64 parallel connected devices working as one system which can pro-vide a load up to 1920 kW 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 4U and one 15 kW 3U device from the ELR 10000 range. Fur-thermore, typical laboratory functionality is provided. This includes an extensive function generator, alarm and warn-ing management, various industrial interfaces, 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 avail-able grid voltage. In a 110/120 V and 208 V AC grid a derat-ing of the DC input power is automatically set.
Energy recovery
The energy consumed in load mode is fed back into the con-nected grid with an efficiency of up to 96%. As the energy is not converted to heat as in other loads, the energy costs are reduced. In addition, the devices generate less heat re-quiring less cost intensive air conditioning. One device can already be sufficient for a while range of applications, reduc-ing investment and installation costs.
The principle of energy recovery
The figure above demonstrates, based on a typical applica-tion, how a „device under test“ consumes energy from the mains, converts it to DC and feeds that into an EA device. The electronic load ELR 10000 converts this energy back into an AC current and feeds it back into the grid.
DC input
The DC input of the electronic loads of ELR 10000 2U series is rated for voltages of 0 - 80 V up to 0 - 1500 V, allowing currents of 0 - 6 A up to 0 - 120 A. The flexible input stages (autoranging) provide the user with a wide voltage, current and power range and hence a wider field of working than traditional power supplies.
DC connection
Connection of the DC input is done via copper blades on the back side of the device. If a system with higher perfor-mance is required, the devices are simply connected in par-allel. With minimal effort devices can be linked with the ver-tical copper rails. A cover for contact protection is provided.
The principle of autoranging
„Autoranging“ is a term used when a programmable elec-tronic DC load automatically offers a wider input range of both, voltage and current, to maintain full power across a wide operation range. This type of solution allows the use of a single unit to address multiple voltage and current com-binations.
Function generator
All models in the ELR 10000 series are equipped with a function generator. This allows curve processes such as sine, triangle, square or trapezoid to be simply called up. A ramp function and an arbitrary generator allow voltage and current progression to be freely programmable. Test sequences for repeated tests can be saved on USB thumb drives and reloaded when needed. That helps to save time. As an extended function of this arbitrary generator, the electronic load can simulate the tracking behavior of a solar inverter, allowing tests of solar panels and modules with a wider range of voltages and power covered by just a single model.
Interfaces
As standard, 10000s series devices are fitted with the most important interfaces and ports which are all galvanically isolated from the DC input. There is an analog interface which can be parameterized for input and output, control and monitoring, of 0 - 5 V or 0 - 10 V for voltage, current, power and resistance, assorted inputs and outputs as well as USB and Ethernet ports. Further optional industrial inter-face for plug & play slot complete the portfolio:
- CAN
- CANopen
- RS232
- Profibus
- EtherCAT
- Profinet, with one or two ports
- Modbus, with one or two ports
- Ethernet, with one or two ports
High performance systems
High power applications can be covered with high power systems of up to 192 kW. These are achieved by using the outputs of many ELR 10000 2U devices and connecting them in parallel using copper rails. A 19” cabinet with a height of 42U can hold up to 16 units of 2U and thus form a system of up to 48 kW occupying only 0.6 m² (6.5 sqft) of floor space. The master/slave bus allows for up to 6 cabi-nets with a maximum of 64 units and up to 3 kW each to behave as one unit.
Master-slave bus and Share-Bus
When the integrated master-slave bus and Share bus are used, a multi device system behaves as a single device. The buses are simply connected between each device. With the master-slave bus the system data, such as total power and total current, are collected and displayed on the master unit. Warnings and alarms of the slave devices are also clearly displayed. The Share bus cares for a balanced load distribu-tion between the individual units.
