EA-PSI 5080-20A 640W Programmable Desktop DC Power Supply

The EA-PSI 5080-20A is a high-performance programmable desktop DC power supply. This microprocessor controlled power supply is engineered for professional laboratory and industrial testing environments, featuring a wide 90-264V AC input with 45-65Hz input frequency, >0.99 active power factor correction (PFC), and high efficiency up to 92% for seamless worldwide deployment and reduced energy consumption. It delivers a flexible 0-80V DC output, 0-20A output current, and 0-640W 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 for diverse testing requirements. The unit offers 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 components and devices. It integrates comprehensive protection systems including overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), and overtemperature protection (OTP) to safeguard both the power supply and connected equipment from damage. The blue LCD display clearly shows all set values, actual values, and status information simultaneously for real-time monitoring. With 9 preset memory groups, users can instantly recall frequently used output configurations, eliminating repetitive adjustments and improving operational efficiency. 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 640W model uses a temperature controlled fan for efficient and quiet thermal management, maintaining optimal operating conditions even under sustained full load. It has compact dimensions of 200x87x331mm and weighs 4.3kg, making it suitable for space-constrained desktop laboratory setups. It meets EMC EN 55022 Class B standards for electromagnetic compatibility. 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.
