EA-PSB 11000-30 3U 10000W Programmable Bidirectional DC Power Supply for Industrial & Laboratory Use

The EA-PSB 11000-30 3U is a high-performance programmable bidirectional DC power supply that integrates the functions of a DC power source (source mode) and an electronic load (sink mode), making it an ideal EA-PSB 11000-30 3U Bidirectional DC Supply for versatile testing scenarios. As a 19" Rack 3U DC Supply, it balances space efficiency with robust performance, delivering a rated power of 10000W Bidirectional Supply (derated to 6000W when operating at 208V ±10% 3ph AC input) to meet the demands of industrial production testing and benchtop power supply from psu applications. This unit supports a wide DC output range: 0-1000V voltage and 0-30A current, with energy recovery efficiency up to 95.5% (at 100% power and voltage) in sink mode—minimizing energy waste and reducing operational costs for power supply supplies users.

Compatible with standard ac supplys (208V ±10%, 3ph AC / 380-480V ±10%, 3ph AC, 45-65Hz), the EA-PSB 11000-30 3U 10000W features comprehensive programmability, supporting four core operating modes: Constant Voltage (CV), Constant Current (CC), Constant Power (CP), and Constant Resistance (CR) (Resistance Mode DC Supply). It is equipped with a built-in Function Generator DC Supply that creates sine, triangular, rectangular, trapezoidal, and arbitrary waveforms (up to 99 points) for dynamic load simulations, plus specialized functions like solar panel MPP tracking and battery charge/discharge testing. For control, it supports 0-5V Analogue Control DC Supply and 0-10V Analogue Control DC Supply via a galvanically isolated 15-pole D-sub interface, plus digital options including LAN Controlled DC Supply (100 MBit Ethernet for HTTP/TCP/IP), Modbus TCP DC Supply, RS232 DC Supply, and CAN DC Supply (via optional IF-AB interface modules). As a power supply with usb, it includes front USB ports for data logging and rear USB for communication/firmware updates, enhancing operational flexibility.

This dc power supply delivers precise performance: load regulation CV ≤0.05% FS, line regulation CV ≤0.01% FS, and display accuracy (voltage ≤0.05% FS, current ≤0.1% FS) to ensure stable power for sensitive equipment. It uses forced air cooling (front inlet to rear outlet) with temperature-controlled fans, operating reliably in 0-50°C (32-122°F) ambient temperatures. Comprehensive safety protections include Overvoltage Protection (OVP, 0-110% U Nominal), Overcurrent Protection (OCP, 0-110% I Nominal), Overpower Protection (OPP, 0-110% P Nominal), and Overtemperature Protection (OT) to safeguard the device and connected loads. Compliant with global standards (EN 61010-1, UL 61010-1, CSA C22.2 No 61010-1, EN 55011 Class B), it is suitable for battery testing, solar inverter validation, fuel cell simulation, and industrial component power cycling. It also supports master-slave parallel operation (up to 64 units) for scalability, fitting both bench power supply needs and large-scale test systems.
