The PSB 9000 bidirectional laboratory power unit from EA Elektro-Automatik combines a power supply and an electronic load with energy recovery in one unit.
The PSB 9000 is primarily a power supply unit. In addition, it fulfils the function of an electronic load, collecting energy and feeding it back into the mains net. The parameters for the power supply as well as those for the electronic load may be adjusted flexibly.
As a power source, the bidirectional power supply can charge and discharge batteries, fuel cells and other energy storages. For this the user can call on multiple integral functions such as battery test mode, an arbitrary generator and a motor vehicle starting curve. As the internal resistance is adjustable, the mode of operation of batteries, fuel cells and photovoltaic modules may be reproduced. In this way, the PSB 9000 supports the development of motor vehicle, hybrid and railway drives.
Furthermore, the EA-PSB 9000 power unit can also feed the energy absorbed in a test process, e.g. on a drive test rig, back into the power source. Here the device must often handle considerable energy with a high dynamic. The EA-PSB 9000 series is capable of collecting this energy with low loss, and feeding it back into the AC grid. Thus, these appliances not only save energy costs but also the investment costs for other electronic or conventional loads.
The units are of modular format. They allow power of up to 15 kW with a flexible output of e.g. 500 V and 90 A in a 3U rack. EA Elektro-Automatik offers a wide range of units with output voltages of 60 V to 1500 V and current of 20 A to 360 A. Additionally, up to 16 units can be connected to create a system of up to 240 kW. This could then be controlled via a four-language HMI or remotely via an interface. As standard, an analog port, a USB port, SCPI and Modbus are built in. Via a plug-and-play slot, further interfaces can be installed. All interface inputs, together with the HMI, are galvanically isolated.
