EA-PSB 11000-10 2U Programmable Bidirectional DC Power Supply & Electronic Load

The EA-PSB 11000-10 2U is a high-precision, bidirectional programmable DC power supply and electronic load in a compact 2U rack-mount design. With a voltage range of 0–1000V, current up to 10A, and power up to 3000W, it serves both as a programmable DC power source and a regenerative DC load, capable of feeding energy back into the grid with up to 95% efficiency. It features an integrated function generator for simulating solar panels (PV), fuel cells, battery test profiles, and various waveform outputs (sine, triangle, rectangle, trapezoid, DIN 40839, arbitrary). Equipped with USB, Ethernet, analog interface, and optional digital bus modules (CAN, Profibus, Profinet, Modbus TCP, EtherCAT, etc.), it supports master-slave parallel operation of up to 64 units. Ideal for R&D, production test, solar inverter testing, battery cycling, and power component validation.

Key Features

• Bidirectional Design: Functions as both a programmable DC power supply and regenerative electronic load in one unit, with seamless source/sink mode switching.
• High Voltage & Power: Delivers 0–1000V, 0–10A, and up to 3000W, with derating to 1500W when operated on 110–127V AC input.
• Energy Recuperation: Recovers up to 95% of energy in sink mode and feeds it back to the AC grid, reducing operating costs and heat dissipation.
• Integrated Function Generator: Supports PV simulation (EN 50530), fuel cell simulation, battery testing, MPP tracking, and arbitrary waveforms for dynamic testing.
• Precise Control & Monitoring: Color TFT touchscreen, rotary encoders, analog interface (0–5V/0–10V), USB logging, and remote control via SCPI/ModBus protocols.
• Expandable System: Share Bus and Master-Slave Bus allow parallel operation of up to 64 units for higher current or power systems.
• Industrial Connectivity: Built-in Ethernet, USB, analog I/O; optional plug-in modules for CANopen, Profibus, Profinet, Modbus TCP, EtherCAT, and more.
• Safety & Protection: OVP, OCP, OPP, OT, Safety OVP (for 60V models), remote sense, and configurable user events for reliable operation.
