EA-PSB 10080-510 3U Programmable Bidirectional DC Power Supply 15000W

The EA-PSB 10080-510 3U is a high-performance programmable bidirectional DC power supply that combines the functionality of a laboratory power supply and an electronic DC load in a single 3U rack-mount unit. With a voltage range of 0-80V, current up to 510A, and power up to 15000W (9000W derated at 208V AC input), this versatile instrument serves as a constant voltage source, constant current source, constant power source, and constant resistance sink. It seamlessly switches between source and sink modes, enabling applications such as battery charge and discharge testing, solar panel simulation, photovoltaic simulator, fuel cell simulator, and automotive test systems. The built-in energy recuperating system feeds energy back into the grid with up to 94.5% efficiency, reducing energy waste and lowering operating costs. Featuring a 5" color TFT touch screen, integrated function generator (sine, triangle, rectangular, arbitrary, and more), and multiple remote interfaces (USB, Ethernet, analog, and optional fieldbus modules), it offers precise control and monitoring. Ripple is ≤10mV rms / ≤100mV pp, and output capacitance is 23970µF. Up to 64 units can be connected in master-slave parallel operation for higher power requirements. Comprehensive protections include OVP, OCP, OPP, and overtemperature shutdown.

Key Features

• Bidirectional Operation with Energy Recovery: Functions as both a programmable DC power supply (source) and an electronic DC load (sink) with seamless zero-crossing switching; energy recuperation feeds up to 94.5% of absorbed power back into the grid, minimizing heat and reducing operating costs.
• High Power Density & Flexibility: Delivers 0-80V, 0-510A, and 0-15000W (9000W at 208V AC) in a compact 3U chassis; ideal for space-saving rack installations and high-current applications like battery testing and cell formation.
• Integrated Advanced Function Generator: Built-in generator supports sine, triangular, rectangular, trapezoidal, arbitrary, PV (EN50530), fuel cell, battery test, and MPPT tracking curves—perfect for simulating solar panels, fuel cells, and automotive load profiles.
• Multi-Interface Remote Control: Standard USB (virtual COM), Ethernet, and galvanically isolated analog interface (0-5V/0-10V); optional plug-in modules for CAN, CANopen, RS232, Profibus, Profinet, ModBus TCP, EtherCAT enable easy integration into industrial automation systems.
• True Master-Slave Parallel Operation: Scalable to up to 64 units via Share bus and digital master-slave bus, achieving total system power up to 960kW with automatic current sharing and summed actual value display on the master.
• Intuitive 5" Touch Screen HMI: Color TFT display with capacitive touch, two rotary knobs, and push-buttons for easy manual operation; real-time graphing, quick menu, and USB host for data logging/sequence storage (CSV format).
• Precise Regulation & Low Ripple: Voltage ripple ≤10mV rms (300kHz BW) / ≤100mV pp (20MHz BW); load regulation CV ≤0.05% FS, CC ≤0.1% FS; display accuracy 0.05% FS for voltage and 0.1% FS for current.
• Comprehensive Protection & Safety: Adjustable OVP, OCP, OPP (0-110% of nominal), overtemperature protection, and Safety OVP on 60V models; reinforced insulation (3750Vrms AC input to DC output) and SELV-compliant models available.
