EA-PSB 10360-120 3U 15kW Programmable Bidirectional DC Power Supply

The EA-PSB 10360-120 3U is a 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 in 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 0‑120 A with a maximum power of 15 kW (derated to 9 kW when operated on 208 V AC input). It features excellent regulation: ≤0.05% FS for voltage, ≤0.1% FS for current, and low ripple (≤55 mV rms, ≤320 mV pp). The built-in arbitrary function generator supports sine, triangle, rectangle, trapezoidal, DIN 40839, EN 50530 PV simulation, and battery charge/discharge profiles. 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 (OVP, OCP, OPP, overtemperature) and user‑definable events ensure safe, reliable operation in R&D and industrial environments.
