Description
Overview
The EA Elektro-Automatik PSB 10360-120 3U is an industrial-strength rackmount bidirectional DC power supply for demanding high-voltage, high-current applications. This 3U unit delivers 360 VDC at 120A (25kW) and operates as both a programmable power source and regenerative electronic load. With three-phase AC input (208-480V), it excels in power electronics testing, battery simulation, and regenerative energy recovery applications.
Key Features
- Bidirectional capability — functions as precision power supply and electronic load simultaneously
- High power density — 25kW in 3U rackmount format with autoranging voltage/current flexibility
- Energy recovery — regenerates 96%+ efficiency power back to three-phase grid in load mode
- Autoranging output stages — maintains constant power across voltage ranges 0-10V to 0-2000V and currents 0-6A to 0-120A
- Digital regulation — 16-bit ADC/DAC resolution with CV, CC, CP, CR control modes and fast mode switching
- Function generator — integrated arbitrary waveform generator with pre-programmed automotive test sequences (LV123, LV124, LV148)
- Master-Slave parallel operation — enables linking up to 64 units for multi-megawatt systems
- Three-phase input — 208-480V with active PFC and automatic range selection
- Touch-controlled interface — 5" TFT color display with navigation and monitoring capabilities
- Integrated simulation modes — battery test, fuel cell simulation, and photovoltaic MPPT (EN 50530)
