EA Elektro-Automatik EA-PSB 10200-50 2U Bidirectional DC Power Supply

Overview

The EA Elektro-Automatik PSB 10200-50 2U is a rackmount bidirectional DC power supply for laboratory and industrial testing applications. This 2U unit delivers 200 VDC at 50A (3000W) and operates as both a power supply and electronic load. It features active power-factor correction and energy recovery capability, regenerating power back to the grid with over 96% efficiency in load mode, significantly reducing operational costs.

Key Features

• Bidirectional operation — functions as both precision power supply and electronic load
• Energy recovery — feeds power back to grid with 96% efficiency, reducing cooling costs
• Autoranging output — flexible voltage and current regulation from 0-10V to 0-1500V, 0-6A to 0-120A
• Digital regulation — 16-bit ADC and DAC for high-resolution control with CV, CC, CP, CR modes
• Function generator — integrated waveform generator supporting sine, triangle, square, trapeze, and arbitrary patterns
• Master-Slave parallel operation — supports up to 64 units for increased power delivery
• Wide AC input range — 110-240V single-phase with automatic voltage selection
• 5" TFT touchscreen display with intuitive interface
