EA-PSB 10360-15 2U Programmable Bidirectional DC Power Supply & Regenerative Load

The EA-PSB 10360-15 2U is a versatile 1500W programmable DC power supply that also functions as a regenerative electronic load (sink) in one compact 2U rack-mount unit. It delivers a precise output of 0-360V and 0-15A. As a true bidirectional power supply, it can seamlessly source power to a device under test or sink (absorb) power from an external DC source while recuperating (feeding back) the absorbed energy into the AC mains with up to 94.5% efficiency. It features a 5-inch color TFT touchscreen (800x480), two rotary encoders with push-button function, and supports multiple remote control interfaces including USB, Ethernet, analog (0-5V/0-10V), and optional digital interface modules (CAN, Profibus, ModBus TCP, etc.). With high accuracy (0.05% voltage, 0.1% current), fast dynamic response (20ms voltage rise/fall, 10ms current rise/fall), and comprehensive protection features (OVP, OCP, OPP, OT), it is an ideal benchtop or system-integrated solution for testing batteries, fuel cells, solar inverters, power supplies, and other DC components.

Key Features

• Bidirectional Operation: Functions as both a programmable DC power source (0-360V, 0-15A, 1500W) and a regenerative electronic load (sink), recovering energy back to the grid.
• High Precision & Stability: Offers excellent voltage and current regulation with ≤0.05% FS load regulation (CV), ≤0.01% FS line regulation (CV), and display accuracy of ≤0.05% for voltage and ≤0.1% for current.
• Fast Dynamic Response: Provides quick settling times with ≤20ms voltage rise/fall (10-90%) and ≤10ms current rise/fall (10-90%).
• Advanced Control & Interfaces: Equipped with a 5" capacitive touchscreen, rotary knobs, built-in USB, Ethernet, isolated analog interface, and a slot for optional digital interface modules (CANopen, Profibus, ModBus TCP, EtherCAT, etc.).
• Integrated Function Generator: Includes arbitrary, sine, triangle, rectangle, trapezoid, ramp, DIN 40839, PV/FC simulation, battery test, and MPP tracking functions for complex test sequences.
• Robust Protection & Safety: Comprehensive safeguards including adjustable OVP, OCP, OPP, overtemperature protection (OT), and meets safety standards (EN/IEC/UL 61010-1).
• Scalable System: Supports master-slave parallel operation of up to 64 units via Share Bus and Master-Slave bus for higher power or current requirements.
• Wide AC Input Range: Operates on 110-127V (±10%) or 208-240V (±10%), 45-65Hz single-phase AC, with automatic power derating on lower voltages.
