EA-PSI 5040-10A 160W Programmable Desktop DC Power Supply

The EA-PSI 5040-10A is a high-performance programmable desktop DC power supply. This microprocessor controlled power supply is ideal for laboratory and testing environments, featuring a wide 90-264V AC input with 45-65Hz input frequency, >0.95 active power factor correction (PFC), and high efficiency up to 92%, enabling seamless worldwide use and reducing energy consumption. It delivers a flexible 0-40V DC output, 0-10A output current, and 0-160W output power with an auto-ranging power stage that allows higher voltage at lower current or higher current at lower voltage within the maximum rated power, making it a versatile flexible power regulated output solution. The unit offers exceptional precision with <0.08% voltage load regulation, <0.02% voltage line regulation, <80mV PP voltage ripple, <10mV RMS voltage ripple, <1.5ms load regulation time, <0.2% voltage accuracy, <0.2% current accuracy, and <1% power accuracy, ensuring stable low ripple output for sensitive equipment. It comes with comprehensive protection features including overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), and overtemperature protection (OTP) to safeguard connected devices. The blue LCD display clearly shows all set values, actual values, and status information at a glance. With 9 preset memory groups, users can easily recall frequently used output settings without repeated adjustments, enhancing work efficiency. This remote controlled power supply supports multiple control interfaces: galvanically isolated analog interface, USB controlled power supply, and Ethernet controlled power supply, and is compatible with SCPI command language, LabView VIs, and Windows control software for seamless integration into automated test systems. It uses natural convection cooling for quiet, maintenance-free operation, has compact dimensions of 200x87x301mm and weighs 3kg, making it perfect for desktop laboratory use. 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 integrated supervision features help reduce test equipment and eliminate the need for external supervision hardware.
