EA-PSB 10060-120 2U Programmable Bidirectional DC Power Supply

The EA-PSB 10060-120 2U is a high-performance, programmable bidirectional DC power supply and electronic load in a compact 2U rack-mount form factor. As a key model in the EA-PSB 10000 series, it delivers 0-60V, 0-120A, and up to 3000W of power (1500W when derated for 110-127V AC input). This unit seamlessly integrates the functionality of a precision benchtop power supply and a regenerative electronic load, enabling source, sink, and automatic sink-source switching operations. It features a high-resolution 5-inch color TFT touchscreen (HMI) for intuitive control, two rotary knobs for quick adjustments, and a comprehensive suite of interfaces including USB, Ethernet, and an isolated analog port for flexible integration. With its advanced energy recuperation capability (up to 94% efficiency), it feeds absorbed DC energy back to the AC grid, reducing operating costs and heat dissipation. It is ideal for testing batteries, fuel cells, solar inverters (with built-in PV/FC simulation), power supplies, and other DC components, offering unparalleled versatility in R&D, production, and quality assurance environments.

Key Features

• Bidirectional Power & Load: Functions as a precise programmable DC power source (0-60V, 0-120A, 3000W) and a high-dynamic electronic load with seamless mode switching.
• High Precision & Stability: Offers excellent accuracy with voltage display ≤0.05% FS and current display ≤0.1% FS, along with superior line regulation (CV ≤0.01% FS).
• Fast Dynamic Response: Provides quick settling times with current rise/fall time (10-90%) ≤10ms and voltage rise/fall time ≤20ms for testing dynamic loads.
• Energy Recuperation (Regenerative): Recovers up to 94% of the absorbed DC energy and feeds it back to the AC mains, improving efficiency and reducing operating costs.
