EA-PSB 10080-340 3U 10000W Bidirectional Programmable DC Power Supply

The EA-PSB 10080-340 3U is a high-density, programmable bidirectional DC power supply from the PSB 10000 3U Series, integrating the functionality of a regenerative DC power supply and a programmable DC electronic load into a single 3U rack mount chassis. This 80V, 340A DC power supply delivers a maximum power of 10000W and features an energy recovery system with up to 94.5% efficiency, feeding energy from sink mode back into the grid. It offers four selectable operating modes: constant voltage (CV) with ≤0.05% load regulation, constant current (CC) with ≤0.1% load regulation, constant power (CP), and constant resistance (CR). The device includes a built-in function generator for arbitrary waveforms and dedicated applications for battery testing, battery charger test systems, solar inverter test equipment, and fuel cell simulation. Standard features include a 5" TFT touch screen, galvanically isolated analog interface, USB (for communication and data logging), and Ethernet (supporting ModBus TCP and SCPI). For applications requiring higher power, such as EV component test systems or DC microgrid simulation, up to 64 units can be connected in parallel via master-slave operation, achieving system power up to 960 kW.
