General
The microprocessor-controlled, bidirectional power supplies of series EA-PSB 9000 3U incorporate two devices in one: a power supply (source) and an electronic load (sink) with energy recovery. Based on these two features the devices offer the functionality of two-quadrants operation as standard. The internal electronic load achieves a high voltage dynamics by discharging the unavoidable capacitance on the DC terminal. For a connected source, the devices are full electronic loads with energy recovery feature, such as the devices from series EA-ELR 9000.
In source operation mode the device becomes a flexible, autoranging power supply like those of series EAPSI 9000. It incorporates the advantages of both device types into one and at the same time it eliminates the disadvantages of separate units regarding weight, space requirement, costs and effort to implement them into custom test software.

AC supply
All models are provided with an active Power Factor Correction (PFC) circuit and are designed for operation on a single phase supply with 230 V (±15%). During load operation, the device regenerates the consumed DC energy and feeds it back into the local power network. This helps saving a lot of energy costs.

Source-sink operation
One salient feature of these devices is the coalescence of an electronic load, also called sink, and a power supply, also called source, into one unit. It means, the device cannot only arbitrarily operate as sink or source, the switchover between these two operating modes occurs without interruption and time loss. This is also called two-quadrants operation.

Energy recovery
The most important feature of these devices is that the AC input while connected to the grid is also used as output for the recovery of the supplied DC energy during load operation, which is converted with an efficiency of up to 95%. This way of energy recovery helps to lower costs and can avoid expensive cooling systems, such as they are required for conventional electronic loads which only convert energy into heat. Operation of these energy recovering devices, in terms of electricity generation, is not intended. Grid protection devices which can supervise the feedback of energy into the public grid are available on the market for optional installation and are installed to achieve additional safety of persons and equipment, especially when running the so-called isolated operation.
