EA-PSB 10200-420 4U 30 kW Programmable Bidirectional DC Power Supply and Electronic Load

The EA-PSB 10200-420 4U is a high-power, programmable bidirectional DC power supply and electronic load in one compact 4U rack unit. It functions seamlessly as both a precision DC source (0-200V, 0-420A, 0-30kW) and a high-efficiency DC sink with energy recovery (regenerative), feeding up to 95.3% of the absorbed power back into the AC grid. Equipped with a 5-inch color TFT touchscreen (HMI), built-in function generator (sine, triangle, rectangle, trapezoid, arbitrary waves, DIN 40839, PV/FC simulation, battery test, MPP tracking), and extensive remote control interfaces (USB, Ethernet, analog, optional CAN, Profibus, Profinet, Modbus TCP, EtherCAT), it is an ideal programmable power supply and electronic load for R&D, production test, and aging applications such as solar panel simulation, battery testing, fuel cell testing, and power supply characterization.

Key Features

• Bidirectional Power Flow: Combines a programmable DC power supply and a regenerative electronic load in one unit for source and sink applications without switching hardware.
• High Power Density & Efficiency: Delivers up to 30 kW in a 4U form factor with up to 95.3% efficiency in both source and sink modes, minimizing energy loss and heat dissipation.
• Advanced Energy Recovery: Recuperates energy when operating as an electronic load and feeds it back into the AC mains with high efficiency, reducing operating costs and cooling requirements.
• Comprehensive Programmable Control: Features multiple operating modes (CV, CC, CP, CR), an integrated function generator for dynamic profiles, and supports master-slave parallel operation of up to 64 units for systems up to 1920 kW.
• Rich Connectivity & Remote Control: Offers standard USB, Ethernet, and isolated analog interfaces, plus optional digital interface modules (CANopen, Profibus, Profinet, Modbus TCP, EtherCAT) for seamless integration into automated test systems.
• Robust Protection & Monitoring: Includes adjustable OVP, OCP, OPP protections, user-definable event monitoring (UVD, OVD, UCD, OCD, OPD), and comprehensive alarm handling for safe operation of sensitive loads.
• Application-Optimized Functions: Built-in simulations for photovoltaics (PV), fuel cells (FC), battery charge/discharge testing, and MPP tracking, making it a complete test solution for renewable energy and energy storage systems.
