EA-PSI 9040-40 DT 1000W Programmable Desktop DC Power Supply

The EA-PSI 9040-40 DT 1000W is a high-performance, programmable DC bench power supply engineered for demanding laboratory, industrial, and research applications requiring substantial power. It delivers a robust output of 0-40V and 0-40A, providing a full 1000W of reliable power. Featuring a universal AC input range of 90-264V with active Power Factor Correction (PFC >0.99) and high efficiency up to 92%, it ensures stable, energy-conscious operation anywhere in the world. The unit incorporates a flexible auto-ranging output stage that intelligently manages voltage and current to deliver the maximum available power from its 1kW capacity. Control is simplified through an intuitive color TFT touch panel, while built-in USB, LAN, and a galvanically isolated analog interface provide seamless integration into automated test systems. Comprehensive protection features including OVP, OCP, OPP, and OT, combined with an integrated true function generator and internal resistance simulation, make this power supply an ideal solution for high-current testing, power device aging, and complex R&D projects where precision and reliability are critical.
