EA-PSB 10060-510 3U 15000W Bidirectional DC Power Supply

The EA-PSB 10060-510 3U is a high-performance programmable bidirectional DC power supply from the PSB 10000 3U series, combining the functionality of a laboratory power supply (source) and an electronic load (sink) in a single 19" 3U chassis. As an energy recuperating system, it seamlessly switches between sourcing and sinking with up to 95.5% efficiency, feeding energy from sink mode back into the grid. This model delivers a voltage range of 0-60V and a current range of 0-510A, with a maximum power of 15000W. It features versatile operating modes including constant voltage (CV) with ≤0.05% load regulation, constant current (CC) with ≤0.1% load regulation, constant power (CP), and constant resistance (CR). Advanced functions include an integrated function generator for arbitrary, sinusoidal, triangular, and rectangular waveforms, as well as specialized modes for battery charge and discharge testing, solar panel simulation (PV), and fuel cell simulation (FC). The unit is equipped with a 5" TFT touch screen, galvanically isolated analog interface, and built-in USB/Ethernet ports. For increased power, up to 64 units can be connected in parallel using master-slave operation, creating systems up to 960 kW.
