EA-PSB 10360-40 3U 5kW Programmable Bidirectional DC Power Supply

The EA-PSB 10360-40 3U is a compact, high-performance programmable bidirectional DC power supply from the PSB 10000 3U series, integrating the functions of a laboratory DC power supply and a regenerative electronic load into a single 3U chassis. As a true dc power supply and sink, it seamlessly switches between source and sink modes with energy recovery up to 95.5% efficiency, making it ideal for battery testing, photovoltaic simulation, fuel cell emulation, and computer power supply testing. This bench power supply delivers 0‑360 V and 0‑40 A with a maximum power of 5 kW (derated to 3 kW when operated on 208 V AC input). It features excellent regulation: ≤0.05% FS for voltage (constant voltage mode), ≤0.1% FS for current (constant current mode), ≤0.3% FS for power (constant power mode), and ≤0.3% FS + 0.1% for resistance (constant resistance mode). Output ripple is exceptionally low at ≤55 mV rms and ≤320 mV pp. The built-in arbitrary function generator supports sine, triangle, rectangle, trapezoidal, DIN 40839, EN 50530 PV simulation, fuel cell (FC) table, battery charge/discharge profiles, and MPP tracking functions. Connectivity includes USB, Ethernet, and a galvanically isolated analog interface (0‑5 V/0‑10 V), plus optional fieldbus modules (Profibus, ProfiNet, ModBus TCP, CANopen, EtherCAT, RS232). Master‑slave parallel operation allows up to 64 units for a total system power up to 960 kW. Comprehensive protections (adjustable OVP, OCP, OPP, overtemperature) and user‑definable events ensure safe, reliable operation in R&D, industrial, and educational environments.
