The bidirectional DC laboratory power supplies of the EA Elektro-Automatik series PSBE 10000 are two-quadrant power supplies that can take on the function of both a power supply and that of an electronic load. In load operation, the DC power supplies work regeneratively and feed the energy back into the local power grid with an efficiency of over 96%. This efficient feedback reduces your costs.
The DC power supplies act as a flexible output stage with a constant performance characteristic, the so-called autoranging, as well as a large voltage, current and power range. In order to achieve higher power and currents, all devices have a master-slave bus. With 64 devices connected in parallel, this enables a system to be set up that provides up to 1920 kW and 64000 A.
The power supplies of the PSBE 10000 series are particularly suitable for automated applications and for remote control . If you are looking for a powerful, bidirectional power supply for development, we recommend the power supplies from the more extensive PSB 10000 series.
The PSBE10080-1703U variant of the EA PSBE10000 series presented here measures 3 HE (3 U) and has 1 channel, 80 V / +/-170 A / 5 kW.
