EA-PSBE 10920-125 4U 30 kW Programmable Bidirectional DC Power Supply

The EA-PSBE 10920-125 4U is a high-performance, programmable bidirectional DC power supply and electronic load within the EA-PSBE 10000 series, delivering up to 30 kW of flexible power. It functions as a true two-quadrant device, operating as both a precise DC source (0-920 V, 0-125 A) and a regenerative sink, feeding recovered energy back into the grid with efficiency up to 96.5%. It features an autoranging output stage, a wide 3-phase AC input range (208-480 V ±10%), active power factor correction (typical 0.99), and advanced digital regulation (CV, CC, CP, CR modes). With its high power density and energy recovery capability, it is engineered for demanding laboratory and industrial applications such as battery simulation, fuel cell testing, on-board charger evaluation, and battery recycling.

Key Features

• Bidirectional & Regenerative: Acts as both a 0-920V power source and an electronic load, recovering energy to the grid with up to 96.5% efficiency in sink mode.
• High Power & Autoranging: Delivers up to 30 kW from a single 4U unit, with a flexible output range of 0-920 V and 0-125 A within a constant power envelope.
• Wide AC Input & High Efficiency: 3-phase input (208-480V ±10%), auto-adjusting, with active PFC (~0.99) and high overall efficiency.
• Precise Regulation & Control: Digital regulation with 16-bit ADCs/DACs, selectable voltage regulation speed (Normal, Fast, Slow), and multiple modes (CV, CC, CP, CR).
• Robust Connectivity & Scalability: Built-in USB, Ethernet, isolated analog interface (DB15). Master-Slave and Share buses for parallel operation of up to 64 units (1920 kW system).
• Comprehensive Protection: Adjustable OVP, OCP, OPP, and overtemperature protection for safe operation.
• Application Ready: Ideal for battery simulation, fuel cell test, on-board charger test, and battery recycling with optional EA-Power Control and EA-Battery Simulator software.
