The models offer extended voltage ranges from 0-10 V to 0-2000 V, a significant increase over previous 9000 series power supplies, and deliver up to 1000 A of output current.
All instruments in the 10000 series operate on the same firmware and feature the same touchscreen user interface. The physical design is identical, and all instruments have similar input and output characteristics. The common programming and user interface save setup and test development time when building test systems with multi-power instrumentation requirements.
All 10000 series devices utilize an autoranging output characteristic (input for electronic loads). Autoranging allows the device to deliver higher voltage capacity at lower currents and higher current capacity at lower voltages than a power supply or load with a conventional rectangular input/output characteristic. Furthermore, a device with an autoranging input/output can deliver/accept its maximum power output over a significant portion of its operating range. This contrasts with an instrument with a rectangular output characteristic, which only delivers maximum power at its maximum voltage and current. The advantage of EA's autoranging capability for a test engineer is access to a wider range of voltages and currents, enabling them to test more applications without requiring multiple power supplies.
Simulate other power devices and create AC + DC signals with the integrated arbitrary waveform function generator. All EA-PSI and EA-PSB power supplies and EA-ELR electronic loads feature an integrated function generator to enable the creation of complex signals on a DC load and to simulate the characteristics of various equipment such as solar cells, batteries, and fuel cells. Special functions enable Maximum Power Point Tracking (MPPT) and EN 50530 for testing solar panel inverters and test sequences based on the LV123, LV124, and LV148 standards for testing automotive systems and components. The integrated functions simplify programming tasks for equipment that simulates various devices and creates output (or input) sequences that comply with major testing standards.
All models in the 10000 series employ active power factor correction, typically 0.99, to minimize power drawn from the grid. In addition, the EA-PSB bidirectional power supplies and EA-ELR electronic loads utilize regenerative circuitry to return energy to the grid with an efficiency exceeding 96%. This regenerative circuitry reduces operating costs and eliminates the need for cooling to dissipate the heat generated by a conventional electronic load.
The 10000 series devices operate efficiently in PC-controlled test systems or PLC-controlled industrial processes. Engineers can easily program the devices using SCPI or Modbus programming modes. The 10000 series devices offer a wide range of interfaces. PC interfaces include Ethernet, USB, and RS-232, while PLC interfaces include CanBus, Profibus, Modbus, Profinet, and EtherCAT, among other options.
Test engineers can connect up to 64 10000 Series power supplies and loads in parallel via the master-auxiliary bus, allowing one instrument to control all instruments in the system. The system can consist of any combination of instrument power levels within the same EA-XXX family (EA-PSB, EA-PSI, EA-ELR, etc.). A galvanically isolated Share-Bus interface on each instrument ensures that all instruments safely share load requirements, enabling the entire rack to operate at full capacity.
