EA-PSI 9040-20 DT 320W Programmable Desktop DC Power Supply

The EA-PSI 9040-20 DT is a versatile and efficient programmable DC bench power supply designed for demanding laboratory and test applications. It delivers a precise output of 0-40V and 0-20A with a maximum power of 320W. Featuring a wide AC input range of 90-264V with active PFC (Power Factor Correction >0.99) and high efficiency up to 88%, it ensures reliable worldwide operation and low energy consumption. The power supply boasts a flexible auto-ranging output stage, allowing it to automatically adjust voltage and current to maximize the available power. It comes standard with an intuitive color TFT touch panel for easy setup and monitoring, and includes built-in USB, LAN, and a galvanically isolated analog interface for seamless remote control and integration into test systems. Comprehensive protection features (OVP, OCP, OPP, OT), an integrated function generator, internal resistance simulation, and a low-noise output with low ripple make it an ideal choice for R&D, education, and production testing.
