Description
Overview
The B&K Precision 9140 series provides three isolated, galvanically-floating output channels in a compact 2U half-rack form factor. Each channel delivers up to 100W of clean power, combining to 300W total output. These multi-range power supplies are designed for benchtop and test system applications requiring precise voltage and current control with advanced programmability and protection features.
Key Features
- Three independent galvanically isolated output channels: 100W per channel or 300W combined
- Multi-range operation delivers rated power at multiple voltage/current combinations
- Output ripple and noise as low as 1 mVrms
- Outputs can be combined to increase voltage up to 180V or current up to 24A
- Advanced list mode programming with up to 10 saved programs
- Channel coupling and tracking functions with configurable delays
- Direct data logging to USB flash drive at adjustable sampling intervals
- Thermostatically controlled fans for quiet operation
- Adjustable voltage and current slew rates
- Built-in web server for remote control of basic settings
- Overvoltage (OVP), overcurrent (OCP), and overtemperature (OTP) protection
- NISPOM-compliant data sanitization for secure factory reset
- LXI compliant LAN, USB (USBTMC), and optional GPIB interfaces
- LabVIEW, IVI-C, and IVI.NET drivers provided
Applications
- Benchtop testing and development of multi-channel systems
- Test system integration with isolated channel requirements
- Device characterization and qualification testing
- Automated production and burn-in testing
