EA-PUB 12000-80 6U WC Programmable Bidirectional DC Power Supply

The EA-PUB 12000-80 6U WC is a high-power, water-cooled version within the EA-PUB 10000 series of programmable bidirectional DC power units. It functions both as a precise power source and as a regenerative electronic load, feeding up to 96.5% of the absorbed energy back into the grid. Designed for demanding industrial and laboratory applications, this 60 kW unit delivers a wide output range of 0 - 2000 V and 0 - 80 A with autoranging capability, ensuring full power across its operating envelope. With a robust three-phase AC input (380 - 480 V ±10%), active PFC (typical 0.99), and comprehensive digital interfaces, it is an ideal solution for battery testing, fuel cell simulation, solar array emulation, and high-power system development.

Key Features

• Bidirectional Operation: Acts as both a high-precision power supply (source) and a regenerative electronic load (sink) with energy recovery efficiency up to 96.5%.
• High Power & Autoranging: Delivers 60 kW (0 - 60000 W) across a wide voltage (0 - 2000 V) and current (0 - 80 A) range, maximizing flexibility for various test profiles.
• Programmable & Precise Control: Features CV, CC, CP, and CR regulation modes with fast crossover. Equipped with 16-bit ADCs/DACs for high-resolution setpoint and measurement.
• Water Cooling (WC Option): The WC version incorporates a water cooling system for efficient heat dissipation, suitable for high-density installations or environments requiring low acoustic noise.
• Scalable System Architecture: Integrated Master-Slave bus and Share-Bus allow parallel operation of up to 64 units, creating systems with power up to 3840 kW that behave as a single instrument.
• Comprehensive Connectivity: Built-in USB, Ethernet, and isolated analog interface (0-10V/0-5V). Optional industrial interfaces include CAN, CANopen, PROFIBUS, EtherCAT, PROFINET, and Modbus.
• Advanced Protection & Safety: Includes adjustable OVP, OCP, OPP, and overtemperature protection. Complies with major safety (EN/IEC/UL 61010-1) and EMC standards.
