OverviewThe EA-PSI 9040-40 DT is a programmable desktop DC power supply delivering 0–40 V and 0–40 A. Available in 640 W and 1000 W power classes, it features an auto-ranging output stage, low-noise filtering and multiple standard interfaces for laboratory, test bench and industrial integration.
Key features- Auto-ranging 0–40 V / 0–40 A: Flexible U/I/P autoranging maximizes usable power across voltage/current combinations.
- Two power variants: 640 W (standard) and 1000 W (high-power) options for high-current applications.
- High efficiency & universal input: Up to 92% efficiency; 90–264 V AC input with active PFC (>0.99).
- Intuitive user interface: Color TFT touchscreen, two rotary knobs and multilingual menu (German, English, Russian, Chinese).
- Standard remote interfaces: USB (control and data), LAN (Ethernet), galvanically isolated analogue interface; supports SCPI and Modbus TCP.
- Integrated function generator & resistance simulation: Built-in true function generator and internal resistance regulation for dynamic testing.
- Protections & low noise: Configurable OVP, OCP, OPP, OT and low ripple (640 W: 8 mVpp / 0.8 mVrms; 1000 W: 10 mVpp / 1.5 mVrms).
