EA-PSB 10200-25 2U Programmable Bidirectional DC Power Supply and Regenerative Load

The EA-PSB 10200-25 2U is a highly versatile and precise 1500W programmable DC power supply that also functions as a fully regenerative electronic load, combining the capabilities of a programmable DC power source and a TPS programmable power style load in one 2U rack-mount unit; as the PSB 10200-25 model, it delivers 0-200V output and 0-25A sink/source current with top-tier performance—including ≤0.05% voltage accuracy and ≤0.1% current accuracy for precise benchtop power supply applications, fast dynamic response with ≤20ms voltage rise/fall time and ≤10ms current rise/fall time for testing dynamic loads, and energy recovery (recuperation) capability with up to 94.5% efficiency in both directions to save energy and reduce heat, and it features a 5-inch color TFT touchscreen with rotary knobs for intuitive how can i test a power supply setups, supports constant voltage (CV), constant current (CC), constant power (CP), and constant resistance (CR) operating modes, includes comprehensive protection (OVP, OCP, OPP, OT, PF) and user-definable monitoring events, offers remote control via analog interface (0-10V/0-5V), USB, Ethernet, and optional digital interface modules (CAN, Profibus, etc.), enables parallel master-slave operation for power scaling, and is designed for applications requiring a top budget PSU with high precision, fast transient response, and bidirectional energy flow such as testing batteries, power supplies, DC-DC converters, and solar inverters.

Key Features

• Bidirectional Power Flow: Functions seamlessly as both a 200V 25A DC power supply and a 1500W regenerative electronic load, enabling source and sink testing without hardware changes.
• High Precision & Fast Dynamics: Delivers ≤0.05% voltage accuracy and ≤0.1% current accuracy for reliable measurements, with ≤20ms voltage and ≤10ms current rise/fall times for dynamic load testing.
• Energy Recovery & High Efficiency: Recovers up to 94.5% of sink mode energy back to the AC grid, reducing operating costs and heat dissipation, acting as an energy-saving regenerative load.
• Advanced Control & Interface: Features a 5" color TFT touchscreen, rotary encoders, and supports remote control via analog (0-10V/0-5V), USB, Ethernet, and optional digital interfaces (CANopen, Profibus, ModBus TCP, etc.).
• Comprehensive Protection & Monitoring: Includes OVP, OCP, OPP, overtemperature, and power fail protections, plus configurable user events (UVD, OVD, etc.) for safe operation of sensitive loads.
• Scalable & Flexible System Integration: Supports master-slave parallel operation for higher power systems and is housed in a standard 2U 19" rack-mount chassis for easy integration into test racks.
