PD2530
Free Instruments Project's PD2530 is a commercial quality, dual channel, dual quadrant bench power supply. Its features include:
- 1mV resolution to 25V.
- 0.1mA resolution to 3A.
- High accuracy (0.1% typical after calibration).
- Source, sink, and downprogramming modes.
- Series, parallel, and bipolar modes.
- Ganged operation between multiple units.
- Dual setpoints and oscillation, including ganged oscillation.
- Hybrid topology with a switchmode preregulator and linear output stage.
- Always-up readouts of the instantaneous output voltage and current.
- Four dedicated, smooth rotary controls for all setpoints.
- USB, RS-232, and Ethernet SCPI control interfaces
- Web control and status interface
