BK 9115B Voltage: 0 - 80 VCurrent: 0 - 60 ACompact, high density, 1U rackmount form factorHigh programming and readback resolutionMulti-ranging operation (output up to max power rating within maximum voltage and current rating) Multi-Range Programmable DC Power Supply, No GPIB The BK Precision 9115 can replace several supplies on your bench or in your rack. Unlike conventional supplies with fixed output ratings, this multi-range power supply automatically recalculates voltage and current limits for each setting, providing full output power in any Volt/Amp combination within the rated voltage and current limits.For benchtop applications, this model provides a numerical keypad for direct data entry along with convenient cursors and analog-style knobs to quickly make incremental voltage or current changes. Systems integrators benefit from the standard USB (USBTMC-compliant), RS-232, and RS-485 interfaces supporting SCPI commands.
