4U power supply EA-PSB 10080-1000 4U

DCregulatedconstant-current

Product overview
The EA-PSB 10080-1000 4U is a 4U rack-mount programmable bidirectional DC power supply combining a precision laboratory DC source and a regenerative electronic load in one unit. It is engineered for demanding industrial and test applications such as high-current battery testing, photovoltaic (PV) simulation and fuel cell testing, with energy recovery to lower operating costs and thermal load.

Key features

• Bidirectional power & energy recovery: Operates as both DC power source and regenerative electronic load; in sink mode recovers energy with up to 95.5% efficiency and feeds it back to the AC mains with automatic seamless switching at zero crossing.
• High power & current output: Up to 30 kW continuous power with 0–80 V voltage range and 0–1000 A current for testing high-power devices and battery packs.
• Advanced programmability & control: 5-inch color TFT touchscreen (HMI), two programmable rotary knobs and remote interfaces including USB, Ethernet, isolated analog 0–5 V / 0–10 V and optional plug-in digital modules (CAN, CANopen, Profibus, Profinet, ModBus TCP, EtherCAT, RS232).
• Integrated function generator: Built-in generator for complex voltage/current waveforms (sine, triangle, rectangle, trapezoid, arbitrary) and sequence profiles for dynamic simulations (PV curves EN 50530, battery profiles, fuel cell characteristics).
• Scalable parallel operation: Master-slave configuration with Share Bus and Master-Slave Bus enabling parallel connection of up to 64 units (synchronized systems up to 1920 kW).
• Comprehensive safety & protections: Configurable OVP, OCP, OPP, over-temperature shutdown and power-fail monitoring; specific variants include Safety OVP for SELV/PELV compliance.
• Flexible data logging & profiles: Front USB port for data logging to USB stick and loading/saving user profiles, arbitrary sequences and PV/FC/IU tables for automated, repeatable testing.
