EA-PSB 10500-60 3U 10000W Programmable Bidirectional DC Power Supply

The EA-PSB 10500-60 3U is a high-performance programmable bidirectional DC power supply from the EA-PSB 10000 Series by Elektro-Automatik. This 10kW model integrates the functions of a laboratory power supply (DC source) and an electronic DC load (sink) into a single 3U chassis for rack mount installation. It delivers a precise DC output with a voltage range of 0-500V and a current range of 0-60A. As a regenerative DC load, it features an energy recovery function with up to 95.5% efficiency, seamlessly switching between source and sink modes without delay. Ideal for complex applications, this programmable power supply includes a versatile function generator capable of creating arbitrary waveforms, sine, triangular, rectangular, trapezoidal, and ramp signals, as well as specialized functions for a photovoltaic PV simulator, solar panel simulator, fuel cell FC simulator, and battery test systems conforming to standards like DIN 40839 for automotive testing. Remote control is facilitated via built-in USB, Ethernet, and a galvanically isolated analog interface, with an optional slot for industrial fieldbus modules. For scalable power requirements, it supports master-slave parallel operation, allowing up to 64 units to be combined for total system power up to 960kW.

Key Features

• True Bidirectional Operation with Energy Recovery: Functions as both a programmable DC power supply (source) and an electronic DC load (sink) with seamless, delay-free switching. In sink mode, it recovers energy with up to 95.5% efficiency, feeding it back into the grid.
• High Power Density and Performance: Delivers 0-500V and 0-60A with a maximum power of 10000W in a 3U form factor. Features excellent load regulation (CV ≤0.05% FS) and low ripple (≤70 mV 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 simulation (EN 50530), fuel cell (FC) simulation, battery testing, and MPP tracking.
• 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.).
