EA-PSI 9040-40 DT 640W / 1000W Programmable Desktop DC Power Supply

The EA-PSI 9040-40 DT is a high-power, programmable DC bench power supply designed for demanding laboratory, test, and industrial applications. It delivers a substantial output of 0-40V and 0-40A, available in two power ratings: a standard 640W model and a high-power 1000W version. Featuring a universal AC input range of 90-264V with active PFC (Power Factor Correction >0.99) and high efficiency up to 92%, it ensures reliable, energy-efficient operation worldwide. The power supply is equipped with a flexible auto-ranging output stage, intelligently adjusting voltage and current to deliver maximum available power. It boasts an intuitive color TFT touch panel for effortless setup and monitoring, and includes built-in USB, LAN, and a galvanically isolated analog interface as standard for seamless integration into automated test systems. Comprehensive protection features (OVP, OCP, OPP, OT), an integrated true function generator, internal resistance simulation, and a low-ripple, low-noise output make it an exceptional choice for high-current R&D, production testing, and educational applications.

Key Features
