DC power supply can operate in tracking mode with user-configurable ratios between channels
B&K Precision's 9130B series triple output linear programmable DC power supplies, available from stock at Digi-Key, feature isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current. Additionally, these supplies can operate in tracking mode with user-configurable ratios between channels. The front panel keys and rotary knob with convenient cursors let users quickly set voltage and current values.
For remote control, the standard USB (USBTMC-compliant), RS232, and GPIB interfaces supporting SCPI commands can be used to remotely control the power supplies via a PC.
