Rack-mount power supply EA-PS 9080-50 1U

DCCERoHS

The EA-PS 9080-50 1U is a microprocessor-controlled unit from the EA-PS 9000 1U series, built for R&D, workshops, electronic testing, and prototype validation. As a 1500W model, it offers 0-80V adjustable voltage and 0-50A variable current (manual/remote adjustment). Its 1U 19“ rack-mount design (19“x1Ux500mm) saves space; the control panel has rotary knobs, pushbuttons, a blue LCD (shows values/status/alarms), and a panel lock to prevent unintentional misuse. It delivers efficient, precise performance: up to 91% efficiency cuts energy loss; active PFC (PF=0.99) works with 100...264V AC grids (45...65Hz). Voltage accuracy <0.1% (rated value), load regulation <0.05%; current accuracy <0.2%, load regulation <0.15%. Low ripple ensures stability—100 mV PP (HF)/5.2 mV RMS (LF) voltage ripple, 4 mA RMS current ripple. It auto-adjusts voltage/current (autoranging) to stay within 1500W, and derates to 1000W at <150V AC input. Galvanically isolated interfaces enable reliable control: analog (15-pole D-Sub, 0...5V/0...10V signals for setting/monitoring), digital (USB + Ethernet, supports SCPI/ModBus RTU). It’s compatible with LabView VIs for custom apps, includes "EA Power Control" software (Windows) for multi-unit management, and supports remote sensing + parallel operation via Share Bus. Safety features include OVP, OCP, OPP, OTP (shuts off DC output on anomalies). Temperature-controlled fans handle cooling. It meets EN 60950/EN 61326/EN 55022 Class B, operates at 0...50 °C (stores at -20...70 °C), and weighs ~10.5 kg—ideal for high-current, medium-power tasks.
