EA-PUB 10920-250 6U 60kW Programmable Bidirectional DC Power Unit

The EA-PUB 10920-250 is a high-power, high-efficiency programmable bidirectional DC power supply and regenerative electronic load in a 6U benchtop form factor. Delivering a full 60 kW, it combines the functions of a programmable DC power source (0-920 V, 0-250 A) and a bidirectional electronic load with energy recovery efficiency up to 96.5%. Designed for demanding high-voltage, high-current applications, its autoranging output, precision digital control, and extensive connectivity make it an ideal regenerative DC power supply for testing battery packs, fuel cell stacks, PV inverters, and power converters.

Key Features

• High-Voltage Bidirectional Operation: Serves as both a programmable DC power source and a regenerative electronic load (sink) with a wide output range of 0-920 V and 0-250 A, achieving up to 96.5% energy recovery efficiency, significantly reducing operational costs and thermal load.
• Constant Power Autoranging (Flexible Output Stage): Provides a full 60 kW across its broad voltage and current ranges, offering unparalleled flexibility as a single-unit solution for diverse testing requirements, replacing multiple fixed-range supplies.
• Precision Digital Control & Measurement: Features CV, CC, CP, and CR regulation modes with fast crossover. High-resolution 16-bit architecture ensures accurate setpoints and measurement (voltage ≤0.05% FS, current ≤0.1% FS). Adjustable voltage control speed adapts to various DUTs.
• Seamless High-Power System Expansion: Integrated Master-Slave and galvanically isolated Share-Bus allow parallel operation of up to 64 units from any power class within the 10000 series (starting from 5 kW), creating synchronized systems up to 3840 kW that operate as a single instrument.
• Comprehensive Standard & Optional Interfaces: Built-in galvanically isolated USB, Ethernet (100 MBit), and analog interface (DB15, 0-5/10 V). Optional plug-in modules for industrial protocols (CAN, CANopen, Profibus, EtherCAT, Profinet, Modbus) enable easy integration into automated test stands (ATE).
• Robust Safety & Compliance: Designed to meet EN/IEC/UL/CSA 61010-1 safety standards. Comprehensive protections include OVP, OCP, OPP, and OT. Complies with relevant EMC directives (EN 61326-1, EN 55011 Class A) for reliable operation in industrial and lab environments.
• Universal Three-Phase AC Input: Wide input range (380-480 VAC ±10%, 3-phase, 45-65 Hz) with active Power Factor Correction (typical 0.99) ensures compatibility with global power grids and reduces harmonic distortion.
• Targeted Applications: Optimized as a core component for Battery Test Systems, Battery Simulator Power Supplies, Fuel Cell Test Power Supplies, On-Board Charger (OBC) Test Systems, Solar Array Simulators, and PV Inverter Test Systems.
