Triple Output DC Power Supply 300W/60V/4A

Brand: BK Precision

B&K Precision’s BK9140 Series is a new generation of DC power supplies featuring a true three-channel design and multi-range operation with industry-leading power density and an enhanced feature set.

The two models in the series, the 9140 (32 V, 8 A) and the 9141 (60 V, 4 A), provide up to 300 W of total output power or 100 W per channel in a compact 2U half-rack form factor. The front panel features a vivid 4.3-inch LCD and output terminals that support sheathed banana plugs or spade lug type connectors. Other features on the front panel include dedicated output control buttons and a USB host port for datalogging.

The series also offers several enhanced features not available on any of B&K Precision’s existing triple output power supplies. For example, advanced list mode programming enables users to set up and execute more complex test sequences. Output sequencing allows users to link the output states between multiple channels with configurable on/off delays. Both models include LXI compliant LAN and USB (USBTMC-compliant) interfaces standard. Remote PC control software and drivers are provided to simplify instrument control and test system integration. For users requiring GPIB, this option is installed with models BK9140-GPIB and BK9141-GPIB.

The BK9140 Series is also cTUVus certified, indicating compliance with Canadian and U.S. National safety standards. The cTUVus mark demonstrates that these power supplies have been successfully tested and certified by a Nationally Recognized Testing Laboratory (NRTL) accredited by the Occupational Safety and Health Administration (OSHA).
