EA-PSB 10080-120 2U Programmable Bidirectional DC Power Supply

The EA-PSB 10080-120 2U is a high-performance 3000W programmable power supply that integrates the functions of both a precision DC power source and an electronic load (sink) into a single 2U rack-mount unit. As a bidirectional DC power supply, it enables seamless energy recuperation, feeding up to 95% of absorbed DC energy back into the AC mains with high efficiency. It delivers 0-80V and 0-120A output with exceptional accuracy (0.05% for voltage, 0.1% for current) and fast dynamic response (10ms current rise/fall, 20ms voltage rise/fall). Featuring a 5-inch capacitive color touchscreen (HMI), built-in function generator for complex waveforms, and extensive remote control interfaces (USB, Ethernet, Analog), it is ideal for testing batteries, fuel cells, solar inverters (PV simulation), power supplies, and other DC components in R&D, production, and laboratory environments.

Key Features
