EA-PUB 11500-120 6U 60000W Programmable Bidirectional DC Power Supply

The EA-PUB 11500-120 is a 60 kW, 6U high-density benchtop unit within the EA-PUB 10000 series of programmable bidirectional DC power supplies. It operates as a precise two-quadrant device, functioning both as a DC power source and a regenerative electronic load. With an output range of 0 - 1500 V and 0 - 120 A, its auto-ranging (constant power) characteristic provides exceptional flexibility. In sink (load) mode, it regenerates energy back to the AC grid with up to 96.5% efficiency, drastically reducing operating costs and heat dissipation. Featuring active PFC (PF~0.99), comprehensive digital control (CV, CC, CP, CR modes), and isolated interfaces (USB, Ethernet, Analog as standard), it is engineered for demanding high-power test applications such as Battery Module/Pack Testing, Fuel Cell Test Systems, On-Board Charger (OBC) Validation, Solar Array Simulation, and Battery Recycling/Discharge.

Key Features

• High Power & Voltage: Delivers 60 kW in a compact 6U (266mm) chassis with a wide 0 - 1500 V output range, ideal for testing high-voltage batteries and components.
• Bidirectional with Energy Recovery: Acts as both source and regenerative sink, feeding up to 96.5% of load energy back to the grid, cutting energy costs and cooling requirements.
• Unmatched System Scalability: Integrated Master-Slave and Share-Bus allows parallel operation of up to 64 units of mixed power ratings (from 5 kW) for systems up to 3840 kW, behaving as a single instrument.
• Precision Performance & Control: Offers high accuracy (Voltage: ≤0.05% FS, Current: ≤0.1% FS), fast transient response (CV rise/fall ≤10 ms), and selectable voltage control speeds (Normal/Fast/Slow) for stable testing of feedback-sensitive devices like OBCs.
• Robust Connectivity & Software: Comes standard with galvanically isolated USB, Ethernet, and analog interfaces. Optional CAN, CANopen, EtherCAT, Profinet, and more. Supported by EA Power Control and EA Battery Simulator software.
• Application-Optimized: Built-in functions for battery simulation, fuel cell testing, and solar IV curve simulation (per EN 50530). Ideal for SOH determination, EOL production testing, and cost-effective battery recycling discharge.
