Description:
The new bidirectional power supplies of series EA-PSB 10000 off much power in in a small space: 30 kW in only 4 units of height (4U). Compared to series EA-PSB 9000 3U it saves a space of 2U, or one third, when considering the 30 kW of rated power. It also incorporates 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, ideal for bigger systems with a total power of up to 1.08 megawatts. In source operation mode the device becomes a flexible, autoranging power supply like those of series EAPSI 9000 3U. 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. |
