Description
Overview
The EA Elektro-Automatik PSB 10200-70 3U is a professional-grade rackmount bidirectional DC power supply for high-power laboratory and industrial testing. This 3U unit delivers 200 VDC at 70A (5000W) and operates as both precision power source and electronic load. With three-phase AC input capability (208-480V), it accommodates industrial power environments while maintaining over 96% efficiency in regenerative load mode.
Key Features
- Bidirectional operation — seamlessly switches between power supply and electronic load modes
- Energy recovery — regenerates power to three-phase grid with 96% efficiency, minimizing energy waste
- Autoranging technology — maintains full power across flexible voltage/current ranges (0-10V to 0-2000V, 0-20A to 0-510A)
- 16-bit digital regulation — high-resolution ADC/DAC with selectable control speeds (Normal, Fast, Slow)
- Four regulation modes — CV (Constant Voltage), CC (Constant Current), CP (Constant Power), CR (Constant Resistance) with fast crossover
- Integrated function generator — programmable waveforms and test sequences with MPPT capability for PV simulation (EN 50530)
- Three-phase AC input — 208-480V automatic detection for global deployment
- Master-Slave parallel capability — link up to 64 units for extended power applications
- 5" TFT color touchscreen with intuitive user controls
- Galvanically isolated interfaces — USB, Ethernet, Analog, plus optional CAN, RS232, Profibus, EtherCAT, Profinet, Modbus
