EA-PSB 10060-60 2U Programmable Bidirectional DC Power Supply

The EA-PSB 10060-60 2U is a versatile and high-performance 60V/60A/1500W bidirectional DC power supply, integrating the functions of a precision laboratory power source and a regenerative electronic load into a single 2U rack-mount unit. It enables seamless transition between sourcing and sinking modes at the zero-crossing point, making it ideal for testing batteries, fuel cells, DC-DC converters, and other energy-related applications. With energy recuperation efficiency of up to 94%, it feeds absorbed DC energy back into the AC grid, reducing operating costs and heat dissipation. The unit features a 5-inch color TFT capacitive touchscreen, dual rotary encoders, built-in USB/Ethernet/analog interfaces, optional industrial communication modules (CAN, Profibus, Profinet, ModBus TCP, EtherCAT, etc.), and supports master-slave parallel operation of up to 64 units for scalable power systems.

Key Features

• Bidirectional Operation: Functions as both a programmable DC power source (0-60V, 0-60A, 0-1500W) and a regenerative electronic load with seamless mode switching.
• High Accuracy & Stability: Voltage regulation ≤0.05% FS, current regulation ≤0.1% FS, with excellent line and load regulation for precise control.
• Fast Dynamic Response: Current rise/fall time ≤10ms, voltage rise/fall time ≤20ms, suitable for dynamic load testing.
• Comprehensive Interfaces: Built-in USB, Ethernet (SCPI/ModBus), isolated analog interface (0-5V/0-10V), and optional plug-in modules for industrial buses (CANopen, Profibus, Profinet, EtherCAT, ModBus TCP).
• Master-Slave Parallel & Series Operation: Supports parallel connection of up to 64 units via Share Bus and Master-Slave Bus for current sharing and power scaling.
• Integrated Function Generator: Generates sine, triangle, rectangle, trapezoid, arbitrary waveforms, and specialized functions for PV simulation, fuel cell testing, battery testing, and MPPT tracking.
• Energy Recovery (Recuperation): In sink mode, inverted DC energy is fed back to the AC grid with up to 94% efficiency, reducing energy consumption and cooling requirements.
• Advanced Protections & Monitoring: Adjustable OVP, OCP, OPP, overtemperature protection, and user-definable events (UVD, OVD, UCD, OCD, OPD) with configurable actions (signal, warning, alarm).
• User-Friendly HMI: 5-inch capacitive touchscreen, dual rotary knobs with push-button function, quick menu, graph display for real-time U/I/P trends, and USB logging capability.
• Rack-Mount Design: Standard 19-inch 2U form factor (482mm width, 88mm height, 559mm depth), weight 9.5kg (1500W model), forced air cooling from front to rear.
