Programmable DC power supply delivers 3000W of output power

The 9115 Series has been extended by B&K Precision with the addition of a new multi-range programmable DC power supply, model 9117. The new instrument can deliver up to 3000W of output power in any combination of voltage up to 80V and current up to 120 A within its power rating.

While offering more than twice the output power as current models in the 9115 Series, the 9117 continues to provide a high density, compact form factor with its 2U 19in rack mountable design.

The power supply's extensive remote interface offerings, increased current range, and low cost-per-watt make it suitable for a variety of benchtop or ATE system applications requiring higher power. Conventional power supplies with fixed output ratings limit the range of voltage and current operation available to the user. The 9117's multi-ranging 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 eliminating the need for large bulky power supplies or multiple units.

Front panel features from the current 9115 Series models carry over to the 9117, which include a bright VFD display, independent voltage and current control knobs, cursors, and a numerical keypad for direct data entry.

The new model also provides internal memory storage to save and recall up to 100 different instrument settings and configurable overvoltage and overpower protection limits. In addition to the standard USBTMC-compliant USB, RS-232, GPIB, and RS-485 interfaces supporting SCPI commands, the 9117 adds a LAN remote interface. The power supply still offers adjustable voltage rise and fall times, master/slave mode for series or parallel connectivity, remote sense, and an analog interface with control and monitoring functions.

The instrument provides external sequence programming capability via remote PC control software.
