EA-PSB 10750-06 2U Programmable Bidirectional DC Power Supply / Electronic Load

The EA-PSB 10750-06 2U is a versatile, high-precision programmable DC power supply and regenerative electronic load in one compact 2U rack-mount unit. As a 750V Programmable Power Supply and a 6A DC Power Supply, it delivers up to 1500W (4500W in master-slave parallel systems) with exceptional accuracy and stability. Its bidirectional design enables seamless operation as both a source and a sink, with energy recovery efficiency up to 95%, feeding regenerated power back to the AC grid. Featuring a 5" color touchscreen (HMI), built-in function generator, and multiple interface options (USB, Ethernet, analog, optional digital modules), it is ideal for testing applications such as fuel cells, solar inverters, batteries, and power semiconductors that require precise, dynamic DC power simulation and loading.

Key Features

• Bidirectional Operation & Energy Recovery: Functions as both a precise programmable DC power source and a regenerative electronic load, recovering up to 95% of sink-mode energy back to the AC line.
• High Voltage & Power: Delivers 0-750V and 0-6A with up to 1500W output, supporting parallel master-slave operation for systems up to 64 units and 4500W total power.
• Excellent Accuracy & Low Ripple: Provides voltage accuracy ≤0.05% FS, current accuracy ≤0.1% FS, and low output ripple (50mV RMS, 500mV pp) for stable, clean DC power.
• Advanced Control & Interfaces: Equipped with a 5" capacitive touchscreen, rotary encoders, built-in USB, Ethernet, isolated analog interface (0-5V/0-10V), and optional plug-in modules (CAN, Profibus, Profinet, ModBus TCP, EtherCAT, etc.) for flexible integration.
• Integrated Function Generator: Includes a versatile function generator for creating sine, triangle, rectangle, trapezoid, arbitrary, DIN 40839, ramp, PV/FC simulation, battery test, and MPP tracking waveforms.
• Robust Protection & Monitoring: Features comprehensive protections (OVP, OCP, OPP, OT, PF, Safety OVP) and configurable user events (UVD, OVD, UCD, OCD, OPD) for safe operation and device/load protection.
• Rack-Mountable Design: Built in a standard 19-inch, 2U-high chassis suitable for test bench or rack cabinet installation with forced air cooling.
