EA-PSI 5040-20A 320W Programmable Desktop DC Power Supply

The EA-PSI 5040-20A is a high-performance programmable desktop DC power supply. This microprocessor controlled power supply is designed for laboratory and testing applications, serving as a reliable EA desktop power supply 5040-20A with a wide 90-264V AC input and 45-65Hz input frequency, featuring >0.97 active power factor correction (PFC) and high efficiency up to 92% for worldwide use and energy savings. It delivers a flexible 0-40V DC output, 0-20A output current, and 0-320W output power with an auto-ranging power stage that enables higher voltage at lower current or higher current at lower voltage within the maximum rated power, making it an ideal flexible power regulated output solution for diverse testing needs. The unit provides exceptional precision with <0.08% voltage load regulation, <0.02% voltage line regulation, <80mV PP voltage ripple, <10mV RMS voltage ripple, <1ms load regulation time, <0.2% voltage accuracy, <0.2% current accuracy, and <1% power accuracy, ensuring stable low ripple output for sensitive electronic equipment. It integrates comprehensive protection mechanisms including overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), and overtemperature protection (OTP) to safeguard both the power supply and connected devices. The blue LCD display clearly presents all set values, actual values, and status information simultaneously for easy monitoring. With 9 preset memory groups, users can quickly recall frequently used output configurations, streamlining workflow and reducing setup time. This remote controlled power supply supports multiple control interfaces: galvanically isolated analog interface for analog controlled power supply applications, USB controlled power supply, and Ethernet controlled power supply, and is fully compatible with SCPI command language, LabView VIs, and Windows control software for seamless integration into automated test systems. The 320W model utilizes a temperature controlled fan for efficient and quiet cooling, maintaining optimal operating temperatures. It has compact dimensions of 200x87x301mm and weighs 3kg, making it suitable for desktop laboratory setups. The 40V model is SELV compliant according to EN 60950 and meets EMC EN 55022 Class B standards. Its intuitive control panel with two knobs and five buttons ensures easy operation, and the built-in supervision features help reduce test equipment and eliminate the need for external supervision hardware.
