ELR10750-122U | Regenerative electronic DC load, ELR 10000, 1 channel, 750V / 12A / 3kW, integr. function generator

The programmable regenerative DC loads of the EA Elektro-Automatik ELR 10000 series work regeneratively and feed the energy back into the local power grid with an efficiency of over 96%. This reduces your costs. since the energy is not converted into heat as with conventional loads.

The ELR 10000 series includes single-phase and three-phase devices that, with their wide AC input range, can serve almost all mains voltages worldwide. The DC voltages and currents are oriented to the application, the spectrum ranges from 0 - 80 V to 0 - 2000 V and from 0 - 6 A to 0 - 1000 A in one device. The DC loads function as a flexible input stage with a constant Performance characteristics, the so-called autoranging, as well as a large voltage, current and power range.

In order to achieve higher power and currents, all devices have a master-slave bus. With 64 devices connected in parallel, this enables a system to be set up that provides up to 1920 kW and a load of 64000 A. This system works like a single device and can consist of different power classes, only the voltage class must match.

A function generator is integrated in all electronic loads of the EA ELR 10000 series. This can be used to call up curves such as sine, triangle, rectangle and trapezoid in the simplest way. Voltage and current curves are freely programmable via a ramp function and an arbitrary generator. Test sequences can be saved for recurring tests and reloaded if necessary, saving valuable time.

EA devices are equipped with the most important digital and analog interfaces as standard, which are also galvanically isolated. This includes an analog interface that has configurable inputs and outputs with 0-5 V or 0-10 V for voltage, current, power and resistance, various functional inputs and outputs as well as a USB and Ethernet interface each.

Typical applications of the ELR 10000 electronic loads from EA Elektro-Automatik include testing the electrical properties of a battery. The wide range of applications includes cell, module or pack tests, the determination of the SOH (state of health) for a second-life classification and the end-of-line test (EOL).

The devices of the ELR 10000 series are ideal for testing the electrical properties of fuel cells, fuel cell stacks and fuel cell systems. They generate highly accurate and reproducible results in all electrical modes. The loads can be easily integrated into an automated test system to test the resistance, performance and lifetime of a fuel cell quickly and inexpensively. The feedback capability guarantees a highly energy- and cost-efficient use.

With the electronic loads, you can check the electrical properties as part of an on-board charger test (OBC). This requires a flexible test system that also provides measurement data. With the sequencing & logging function, test sequences can be loaded into the ELR 10000 devices and data can be read out and saved.

With the programmable electronic loads of the ELR 10000 series, discarded batteries from electric vehicles can also be checked for their possible further use. When characterizing the battery pack, the battery is first checked for its remaining capacity (state of health) in order to determine its suitability for a second life. This permanently integrated function can be called up at the push of a button.

The ELR 10750-12 variant of the ELR 10000 electronic load series presented here measures 2 HE (2U) and has 0 - 750 V, 0 - 12 A, 0 - 3,000 W and, like all models in the ELR 10000 series, an integrated function generator.

General characteristics of the series:

  • Wide input range, 110V - 240V +10% 1ph AC
  • Active power factor correction, typically 0.99
  • Regenerative with energy feedback into the grid
  • Very high efficiency of over 95%
  • Voltage from 0 - 80 V to 0 - 2000 V
  • Current from 0 - 20 A to 0 - 510 A
  • Flexible power-controlled DC input stage (autoranging)
  • Control mode CV, CC, CP, CR with fast transition
  • Digital control, high resolution with 16bit ADCs and DACs, control speed selection: Normal, Fast, Slow
  • Colored 5" TFT display, touch function and intuitive operation
  • Galvanically isolated share bus for parallel operation of all performance classes in the 10000 series
  • Master-slave bus for parallel operation, up to 64 devices of all performance classes of the 10000 series
  • Integrated function generator with predefined curves
  • Integrated battery test
  • Photovoltaic test mode, MPPT
  • Standard interfaces: USB, Ethernet, analog, USB host, master-slave bus, share bus
  • Optional interfaces: CAN, CANopen, RS232, Profibus, EtherCAT, Profinet with one or two ports, Modbus with one or two ports, Ethernet with one or two ports
  • Command languages and drivers: SCPI and ModBus, LabVIEW, IVI
