EA-PSI 10750-12 2U 3000W Programmable DC Power Supply

The EA-PSI 10750-12 2U is a high-performance, programmable DC power supply designed for demanding test systems and industrial applications. Housed in a compact 19-inch, 2U rack-mount chassis, it delivers a wide output range of 0-750V DC and 0-12A DC, with a maximum power of 3000W (1500W when derated for 110-127V AC input). It achieves high efficiency of up to 95%, ensuring minimal energy loss and heat generation. The unit features a color TFT touchscreen interface for intuitive manual control and is equipped with a built-in function generator capable of producing sine, triangle, rectangle, trapezoidal, and arbitrary waveforms. For system integration and automation, it offers standard USB and Ethernet ports, an isolated analog interface (0-5V/0-10V), and a slot for optional digital interface modules (CAN, CANopen, Profibus, Profinet, ModBus TCP, EtherCAT, RS232). Its master-slave and Share BUS capabilities allow parallel operation of up to 64 units, creating systems with total power up to 192kW. With precise regulation, comprehensive protection features, and robust construction, the EA-PSI 10750-12 2U is an ideal, reliable power source for R&D, production testing, and complex system simulations.
