EA-PSB 10500-30 3U 5000W Programmable Bidirectional DC Power Supply

The EA-PSB 10500-30 3U is a high-performance programmable bidirectional DC power supply from the PSB 10000 3U series, integrating the functionality of a laboratory power supply (source) and an electronic load (sink) into a single, compact 3U chassis for 19" rack installation. As a key component for automated test systems, this 5000W model delivers a voltage range of 0-500V and a current range of 0-30A, with an impressive energy recovery efficiency of up to 95.5%. This bidirectional DC power supply seamlessly switches between sourcing and sinking without delay at the zero point, making it ideal for complex testing scenarios. It features a built-in function generator with modes including arbitrary, PV, and battery test functions, along with comprehensive remote control options via USB, Ethernet, and an isolated analog interface. For enhanced power requirements, it supports master-slave parallel operation with true totalization of actual values, offering a scalable solution up to 960kW.

Key Features

• True Bidirectional Operation with Energy Recovery: Functions as both a DC power supply (source) and an electronic load (sink) with seamless, delay-free switching. In sink mode, it recovers energy with up to 95.5% efficiency and feeds it back into the grid.
• High Power Density and Performance: Delivers 0-500V and 0-30A with a maximum power of 5000W in a 3U form factor. Features excellent load regulation (CV ≤0.05% FS) and low ripple (<70mV rms).
• Integrated Multi-Function Generator: Includes a versatile function generator for creating complex sequences such as sine, triangular, rectangular, trapezoidal, ramp, and arbitrary waveforms, as well as specialized functions for PV (EN 50530), fuel cell (FC), and battery testing.
• Comprehensive Remote Control & Connectivity: Standard with galvanically isolated USB, Ethernet, and analog interfaces. An optional slot allows for plug-in modules (Profibus, ProfiNet, CANopen, ModBus TCP, EtherCAT) for seamless integration into industrial networks.
• Scalable Master-Slave Parallel Operation: Allows for easy parallel connection of up to 64 units via Share-Bus and digital master-slave bus, creating a high-power system with total current and power displayed on the master unit.
• Advanced Protection and Safety Features: Equipped with adjustable overvoltage (OVP), overcurrent (OCP), overpower (OPP), and overtemperature (OT) protection. Also features adjustable protection limits and user-definable events (UVD, OVD, etc.).
