B&K Precision Expands 1U System Power Supply Offerings

May 21, 2013. B&K Precision has expanded its DC system power supply offerings with the introduction of the Model 9115 multirange programmable DC power source. The 9115 can deliver up to 1,200 W in multiple combinations of voltage up to 80 V and current up to 60 A. With a high-density, compact 1U form factor and standard 19″ rack-mountable design, this DC power supply can replace multiple power supplies on a bench or in a rack, making it suitable for a variety of bench-top or ATE system applications.

Conventional power supplies with fixed output ratings often limit the range of voltage and current operation available to the user. The 9115’s multiranging capability automatically recalculates voltage and current limits for each setting and can provide wide voltage and current operating ranges without forfeiting high output power, thus saving valuable bench space by eliminating the need for large bulky power supplies or multiple units.

On the front panel, the 9115 features a high resolution, 1-mV/1-mA VFD display, independent voltage and current control knobs, cursors, and a numerical keypad for direct data entry. The instrument also provides internal memory storage to save and recall up to 100 different instrument settings.

For programming and remote control, the 9115 offers a plethora of features to the user: adjustable voltage rise and fall times, sequence (list mode) programming, master/slave mode for series or parallel connectivity, remote sense, a DB25 analog interface with control and monitoring functions, and standard USBTMC-compliant USB, RS-232, GPIB, and RS-485 interfaces supporting SCPI commands.

Furthermore, the 9115 provides configurable overvoltage and overpower protection limits and a front-panel key-lock function to prevent accidental damage to a device under test.

Available immediately, B&K Precision's 9115 multi-range programmable DC power supply has a list price of $1,695.
