Tabletop power supply EA-PSI 5080-20A

DCvariable-outputadjustable

Overview
The EA-PSI 5080-20A is a high-performance programmable desktop DC power supply engineered for professional laboratory and industrial testing. It features a wide universal input (90-264V AC, 45-65Hz) with >0.99 active PFC and up to 92% efficiency. The unit provides an auto-ranging DC output of 0-80V, 0-20A and up to 640W, permitting higher voltage at lower current or higher current at lower voltage within the rated power. It delivers very low ripple, fast response and integrates multiple protections and remote-control interfaces for automated test systems.

Performance and Accuracy
Output range and power: 0-80V DC, 0-20A, 0-640W (auto-ranging power-regulated stage). Precision and stability: <0.08% voltage load regulation, <0.02% voltage line regulation, <80mVpp / <10mVrms voltage ripple, <1ms load regulation time, <0.2% voltage accuracy, <0.2% current accuracy, <1% power accuracy.

Protection, Control and Interfaces
Integrated protections: overvoltage protection (OVP), overcurrent protection (OCP), overpower protection (OPP), overtemperature protection (OTP). User interface: blue LCD displaying set and actual values and status simultaneously; intuitive front panel with two knobs and five buttons; 9 preset memory groups for quick recall. Remote control: galvanically isolated analog interface, USB and Ethernet. Compatible with SCPI command language, LabView VIs and Windows control software for integration into automated test environments.

Thermal, Mechanical and Compliance
Thermal management: temperature-controlled fan providing quiet operation under sustained load. Dimensions: 200 x 87 x 331 mm. Weight: 4.3 kg. Electromagnetic compatibility: meets EMC EN 55022 Class B. Built-in supervision features reduce the need for external monitoring hardware.
