BK Precision 9141 Programmable DC Power Supply

The BK Precision 9141 is a versatile triple-output, multi-range DC power supply designed for demanding B2B applications. It offers three independent, floating output channels, each capable of delivering up to 100W of clean power with low ripple and noise characteristics, totaling 300W. This unit is housed in a compact 2U half-rack form factor, making it suitable for both benchtop use and integration into test systems. The multi-ranging capability allows for flexible output configurations, and channels can be combined to achieve higher voltage or current outputs as needed. Advanced features include list mode programming for complex test sequences, channel coupling and tracking, configurable delays, and direct data logging to a USB flash drive. It also includes adjustable voltage and current slew rates, along with comprehensive protection features such as Over Voltage Protection (OVP), Over Current Protection (OCP), and Over Temperature Protection (OTP). For connectivity, the BK Precision 9141 supports USB (USBTMC-compliant) and LXI compliant LAN, with a GPIB option available for enhanced system integration. Compatibility with LabVIEW, IVI-C, and IVI.NET drivers simplifies development and integration into automated test environments.
