EA-PSB 10060-1000 4U Programmable Bidirectional DC Power Supply

The EA-PSB 10060-1000 4U is a high-power, programmable bidirectional DC power supply and electronic load in one robust 4U rack-mount unit. As part of the EA-PSB 10000 4U series, this 30 kW system delivers 0-60V and 0-1000A, seamlessly switching between source (providing power) and sink (absorbing power as an electronic load) modes. Its key feature is energy recuperation (recuperating device), feeding up to 95.1% of the absorbed DC energy back into the AC mains with high efficiency, making it ideal for energy-conscious testing and aging applications. Equipped with a 5" color TFT touchscreen (HMI), dual rotary knobs, extensive digital interfaces (USB, Ethernet), and a galvanically isolated analog interface, it offers precise manual and remote control. It supports advanced functions like a built-in arbitrary waveform generator, master-slave parallel operation (up to 64 units), and simulation modes for photovoltaic (PV), fuel cell (FC), and battery testing, establishing itself as a versatile and powerful solution for R&D, qualification, and production test environments.

Key Features

• Bidirectional Power & Electronic Load: Integrates a programmable DC power supply and a high-speed electronic load in one device, enabling seamless source-sink operation for testing batteries, power supplies, and other energy sources/sinks.
• High-Efficiency Energy Recuperation: Recovers up to 95.1% of the absorbed DC power in sink mode and feeds it back into the AC grid, significantly reducing energy costs and heat dissipation during long-term testing.
• High Power & Precision: Delivers 30 kW with 0-60V and 0-1000A output, featuring excellent regulation (CV ≤0.05% FS, CC ≤0.1% FS) and display accuracy (Voltage ≤0.05% FS, Current ≤0.1% FS) for demanding applications.
• Advanced Control & Interfaces: Features a 5" capacitive touchscreen, dual control knobs, USB data logging, Ethernet, isolated analog interface (DB15), and optional digital bus modules (CANopen, Profibus, Profinet, ModBus TCP, EtherCAT, etc.) for seamless integration into automated test systems.
• Comprehensive Safety & Protection: Includes user-adjustable OVP, OCP, OPP, overtemperature (OT) protection, and mandatory grounding for safe operation with high-power circuits.
• Versatile Application Functions: Built-in function generator (sine, triangle, rectangle, trapezoid, arbitrary waves), battery test simulator, and simulation modes for photovoltaic (PV) panels and fuel cells (FC) according to standards like EN 50530.
• Scalable System: Supports master-slave parallel operation with Share Bus and Master-Slave Bus, allowing up to 64 units to be combined for systems up to 1920 kW total power.
