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

The EA-PUB 10920-250 6U WC is a high-performance, programmable bidirectional DC power unit designed for demanding laboratory and industrial applications. This water-cooled variant delivers a robust 60 kW of continuous power within a wide autoranging output range of 0-920 V DC and 0-250 A. Operating as both a precise power source and a regenerative electronic load, it can recover energy back into the AC grid with an exceptional efficiency of up to 96.5%, significantly reducing operational costs and heat dissipation. It features three-phase AC input (380-480 V ±10%) with active Power Factor Correction (typical 0.99), advanced digital regulation with 16-bit ADCs/DACs, and supports parallel operation of up to 64 units via integrated Master-Slave and Share-Bus systems for scalable power solutions up to several megawatts.

Key Features

• Bidirectional & Regenerative Operation: Functions as both a high-precision DC power supply (source) and an electronic load (sink), with energy recovery into the grid at up to 96.5% efficiency.
• High Power & Wide Autoranging Output: Delivers 60 kW across a flexible range of 0-920 V DC and 0-250 A, providing constant power over a broad operating area.
• High-Efficiency Active PFC Input: Accepts three-phase AC input from 380 V to 480 V with a power factor of approximately 0.99, minimizing grid impact.
• Advanced Digital Control: Equipped with 16-bit ADCs and DACs for high-resolution setpoint and measurement, with selectable voltage controller speed (Normal, Fast, Slow).
• Comprehensive Interfaces: Built-in USB, Ethernet, and isolated analog (DB15) interfaces. Optional industrial communication interfaces include CAN, CANopen, PROFIBUS, EtherCAT, PROFINET, and Modbus.
• Scalable Parallel System: Integrated galvanically isolated Master-Slave and Share-Bus allows seamless parallel connection of up to 64 units of different power ratings (same voltage class) to act as a single, high-power system.
• Robust Protection & Monitoring: Includes adjustable OVP, OCP, OPP, and overtemperature protection. Provides accurate measurement (Voltage ≤0.05% FS, Current ≤0.1% FS).
• Water Cooling Option (WC): Enhanced cooling solution for high-power density applications, ensuring reliable operation and reduced acoustic noise compared to forced air cooling.
• Application Versatility: Ideal for battery testing & simulation (cell/module/pack), fuel cell testing, on-board charger (OBC) test, solar array simulation, and battery recycling processes.
