Description
The bidirectional DC laboratory power supplies in the PUB 10000 series from EA Elektro-Automatik are two quadrant devices which can perform the function of a power supply (source) as well as that of an electronic load (sink). In sink mode the device is regenerative and feeds the energy back into the local grid with an efficiency of up to over 96%. The PUB 10000 series are three phase units which, together with the wide input range, allows use with practically all global mains voltages. The DC voltages and currents are determined by the application and the spectrum ranges from 0 - 60 V to 0 - 2000 V and from 0 - 40 A up to 0 - 1000 A in a single device. The DC supply operates as a flexible output stage with a constant power characteristic (auto-ranging) with a wide voltage and current range. To achieve higher power and current all units are equipped with a Mas-ter-Slave bus. This enables up to 64 parallel connected de-vices to be combined into one system which can provide up to 3840 kW and 64000 A. Such a system works as a single unit and can use different power classes start from 5kW, only the voltage class must remain constant. In this way a user can construct a 150 kW system from two 60 kW 6U and one 30 kW 4U device from the PUB 10000 range. Fur-thermore, typical laboratory functionality is provided. This includes alarm and warning management, various option-al industrial interfaces, software solutions and many more functions.

- Very high efficiency of up to 96%
- High performance of 30 kW per unit
- Voltages from 0 - 60 V up to 0 - 2000 V
- Currents from 0 - 40 A up to 0 - 1000 A
- Flexible power regulated DC output/input stage (auto-ranging)
- Regulation modes CV, CC, CP, CR with fast crossover
- Digital regulation, high resolution with 16 bit ADCs and DACs, selection of voltage control speed
- Galvanically isolated Share-Bus for parallel operation of all power classes in the 10000 series
- Master-Slave bus for parallel operation of up to 64 units of same type in all power classes of the 10000 series
- Command languages and drivers: SCPI and ModBus, LabVIEW, IVI
AC connection
The DC power supplies in the PUB 10000 series with 30 kW 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 with 3-phases from 208 - 240 V (with a derating to 18 kW) and 380 - 480 V. Hence the devices can be operated in the majority of global grids.
Energy recovery
The energy consumed in load mode is fed back into the connected grid with an efficiency of up to over 96%. As the energy is not converted to heat as in other loads, the en-ergy costs are reduced. In addition, the devices generate less heat requiring less cost intensive air conditioning. One device can already be sufficient for a while range of applica-tions, reducing 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 bidirectional power supply PUB 10000 converts this en-ergy back into an AC current and feeds it back into the grid.
DC output
The output of the bidirectional power supply PUB 10000 with 30 kW with a DC voltage of 0 - 60 V up to 0 - 2000 V allows positive and negative currents of 0 - 40 A up to 0 - 1000 A as a two quadrant device. The flexible output 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 output is via a copper rail on the back side of the device. If a system with higher performance is required, the devices are simply connected in parallel. With minimal effort devices can be linked with the vertical cop-per rails. A cover for contact protection is provided.
The principle of autoranging
„Autoranging“ is a term when a bidirectional programma-ble DC power supply automatically offers a wide output and 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 combinations.
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 1920 kW. These are achieved by using the DC outputs of multiple PUB 10000 devices with vertical copper rails in parallel. Thus, a 19” cabinet with 42 U can provide a system with 300 kW occupying only 0.6 m² (6.5 sqft) of floor space. The Master-Slave bus allows for up to 13 cabinets with a maximum of 64 units with 30 kW each to behave as one unit.
Master-slave bus and Share-Bus
If the integrated master-slave bus and Share-Bus are used, a multi device system behaves as a single device. The mas-ter-slave bus and Share-Bus are simply connected between each device. With the master-slave bus the system data, such as total power and total current, are collected and shown on the master device. Warnings and alarms of the slave devices are shown clearly in the display. The Share-Bus equal load distribution to the individual devices.
