Series PSB 9000 3U 2,5 kW

The microprocessor-controlled, bidirectional power supplies of series EA-PSB 9000 3U incorporate two de-vices 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 electron-ic 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 EA-PSI 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.
