EA Elektro-Automatik offers with their EA-PSB 10000 30kW the current widest performance range on the market.
With just 4 HE the device surprises with a performance of 30kW. For comparison: the previous model offered 15kW
from 3 HE.
ratio on the market
Thus the power ratio could be raised from 5kW/HE to 7.5kW/HE within one device generation, an
increase of 50 percent.
Up to 1.92 MW is possible
With a large number of objects to be tested this power soon becomes inadequate. Therefore EA Elektro-Automatik
provides cabinet systems for its customers in which multiple EA-PSB 10000 30kW units can be operated in
parallel, allowing a total power of up to 1.92 MW to be achieved.
The new EA-PSB 10000 30kW (figure 1) is persuasive not only through its high performance. As a programmable bi-directional
DC mains unit it offers the user the possibility to model different operating conditions precisely. For
instance, if an energy store is required to be charged and discharged in differing power steps, this can be done
with just one device. For this the autoranging function is particularly valuable for the user. Here the
programmable bidirectional source has the capability to provide an increased current at a reduced output
voltage. Discharging, e.g. of a high voltage battery, can feedback up to 96 percent of the stored energy
directly to the mains. For applications requiring ever higher voltages EA has developed a device with 2000V
output voltage. In addition there is a device with 60V output voltage for SELV applications.
