EA-PUB 12000-80 60 kW Programmable Bidirectional DC Power Supply

The EA-PUB 12000-80 is a high-performance, programmable bidirectional DC power supply and electronic load, capable of delivering up to 60 kW with an output voltage range of 0-2000 V and current up to 80 A. As part of the EA-PUB 10000 series, this 6U rack-mount unit operates in both source and sink modes, featuring regenerative energy recovery to the grid with efficiency up to 96.5%. It is designed for demanding applications such as battery testing, fuel cell test systems, on-board charger (OBC) testing, solar array simulation, and battery recycling. With advanced digital regulation (CV, CC, CP, CR), auto-ranging (autoranging) capability, and support for parallel operation of up to 64 units, the PUB 12000-80 offers flexibility, precision, and scalability for high-power test systems.

Key Features

• Bidirectional Operation: Functions as both a programmable DC power supply (source) and regenerative electronic load (sink), with energy recovery to the grid at up to 96.5% efficiency.
• High Voltage & Power: Delivers 0-2000 V DC, 0-80 A, and 60 kW constant power, suitable for high-voltage applications like PV inverter testing and battery pack validation.
• Auto-Ranging (Autoranging): Provides a wide voltage and current range within a constant power curve, allowing a single unit to cover multiple test points without derating.
• Parallel & System Scalability: Equipped with galvanically isolated Master-Slave bus and Share-Bus for parallel operation of up to 64 units (up to 3840 kW total), supporting mixed power classes within the same voltage range.
• High Efficiency & Grid Feedback: Active PFC (≈0.99), up to 96.5% efficiency in both directions, reducing energy costs and thermal load.
• Advanced Regulation & Protection: Digital control with 16-bit ADC/DAC, selectable voltage controller speed (Normal/Fast/Slow), and adjustable OVP, OCP, OPP, and OT protection.
• Comprehensive Interfaces: Built-in USB, Ethernet, analog (DB15), Master-Slave bus, Share-Bus; optional CAN, CANopen, RS232, Profibus, EtherCAT, Profinet, Modbus.
• Application Ready: Ideal for battery test systems, fuel cell testing, on-board charger (OBC) test, solar array simulation, PV inverter test, battery simulation, SOH (State of Health) testing, and battery recycling/discharging.
