EA-PSB 10000: Maximum efficiency in battery and fuel cell testing
May 12, 2021Growing demands placed on modern batteries and accumulator systems present manufacturers with major challenges. On one hand, their systems have to provide more performance, service life and safety; on the other hand, end consumers expect products that have an attractive purchase price and energy-efficient operation. Therefore, modern bidirectional DC power supplies like our EA-PSB 10000 30 kW play a central role.
Our EA-PSB 10000 30 kW series offers currently the highest power density on the market in 4U height. In parallel operation a total output of up to 1.92 MW can be achieved. As this is also a programmable bidirectional DC power supply unit, users benefit from advanced capabilities under different operating conditions.
If, for example, energy storage devices need to be charged and discharged at different power levels in order to test them, this can be done with just one device. In this context, our autoranging function is particularly valuable for users. Here, the programmable bidirectional source has the ability to provide an increased current at a reduced output voltage.
EA-PSB 10000 30 kW can operate either as a sink or a source and can also switch seamlessly between the two operating modes without any loss of time, which means maximum efficiency. Further advantages are that users will enjoy lower acquisition costs, lower space requirements, lower maintenance and the convenience of test software integration in a single device.
With EA-PSB 10000 30 kW's efficient mains feedback of up to 96%, users can reduce primary energy costs when performing tests. In contrast to conventional systems, this also reduces the heat generated by the devices as well as the costs for air conditioning. In addition to the standard forced air cooling, all models of the 30 kW / 4U technology are available with water cooling. A closed unit housing without ventilation slots prevents the exchange of internal and external ambient air. More than 90% of the heat generated from the unit is dissipated by the water flow.
