EA-PSB 10750-12 2U 750V/12A/3000W Programmable Bidirectional DC Power Supply and Electronic Load

The EA-PSB 10750-12 2U is a versatile and high-efficiency programmable DC power supply that also functions as a fully-featured electronic DC load. As a 750V Programmable Power Supply with a 12A Programmable Power Supply current rating, it delivers up to 3000W Programmable Power Supply output. Its core innovation lies in being a true Bidirectional DC Power Supply, seamlessly integrating source and sink functionalities. In Sink Mode, it acts as an advanced Electronic DC Load with an Energy Recuperating System that feeds up to 95% of the absorbed DC energy back into the AC mains, drastically reducing operating costs and heat dissipation. This makes it an ideal TPS Power Supply solution for test benches requiring both power sourcing and loading.

This unit is packed with advanced application features. It includes a powerful built-in function generator for creating complex voltage or current profiles (sine, triangle, rectangle, trapezoid, arbitrary). Specialized modes allow it to function as a Solar Panel Simulator (PV) for PV Inverter Test, a Fuel Cell Simulator (FC), and a comprehensive Battery Test System for precise Battery Charge Test and Battery Discharge Test cycles. The 5-inch color TFT touchscreen provides intuitive manual control, while extensive remote control options are available via standard interfaces (USB, Ethernet, isolated analog) or optional plug-in modules (CAN, Profibus, Profinet, Modbus TCP, EtherCAT). For high-power requirements, up to 64 units can be combined in a master-slave parallel system with automatic current sharing.
