Beskrivelse
The bidirectional DC laboratory power supplies in the PSB 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 96%. The PSB 10000 series includes single and three phase units which, together with the wide input range, allows use with prac-tically all global mains voltages. The DC voltages and cur-rents are determined by the application and the spectrum ranges from 0 - 10 V to 0 - 2000 V and from 0 - 6 A up to 0 - 1000 A in a single device. The DC supply operates as a flexible output stage with a constant power character-istic (autoranging) with a wide voltage and current range. To achieve higher power and current all units are equipped with a master-slave bus. This enables up to 64 parallel con-nected devices to be combined into one system which can provide 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 PSB or PSBE 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 DC power supplies in the PSB 10000 series are equipped with an active PFC which provides a high efficien-cy at a low energy consumption. Furthermore, the devices in this series provide a wide input voltage range. It reach-es 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. In a 110/120 V and 208 V AC grid a derating of the DC output 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 bidirectional power supply PSB 10000 converts this en-ergy back into an AC current and feeds it back into the grid.
DC output
The DC output of the bidirectional power supply series PSB 10000 2U is rated for DC voltages of 0 - 10 V up to 0 - 1500 V, allowing positive or negative currents of 0 - 6 A up to 0 - 120 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 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 bidirectional program-mable DC power supply automatically offers a wider 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.
Function generator
All models in the PSB 10000 series are equipped with a function generator. This allows waveforms such as sine, tri-angle, square or trapezoid to be simply called up and applied to either the voltage or the current. A ramp function and a arbitrary generator allow voltage and current progression to be freely programmable. Test sequences for repeated tests can be saved and reloaded when needed, which saves time. For simulation of a photovoltaics system or fuel cells, adapt-able tables are provided. With the integrated and adjustable PV characteristics curve DIN EN 50530 various solar mod-ules can be defined and entire day trend progression can be simulated.
Conclusion: the user is supported by a multitude of useful functions.
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 PSB 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.
