B+K Precision Models BK9240(-GPIB), BK9241(-GPIB), BK9242(-GPIB) DC Power Sources

The B+K Precision BK9240 is a series of general purpose DC power supplies up to 200 W. The devices offer advanced list programming features, battery charge mode, and data logging. They can be used in production test, R&D, electronic service, education and other industrial and lab applications.

The battery charge mode provides configurable fail-safe settings to disable the output when a specified energy, capacity, or time threshold is reached protecting both the power supply and battery. Battery charge data including Wh, Ah, and time can be logged directly to a USB flash drive connected to the front panel USB host port. User-configurable battery charge profiles, instrument settings, and list mode programs can also be saved/recalled from the USB host port.

  • Isolated and floating output with front panel remote sense.
  • Up to 120 W or 200 W of multi-range power in a compact 2U half-rack form factor.
  • Clean output power with less than 1 mVRMS of noise.
  • Advanced list mode programming with internal storage for 10 list mode programs.
  • Battery charge mode with fail-safe conditions.
  • Direct data logging to a USB flash drive.
  • Overvoltage (OVP), overcurrent (OCP), overtemperature (OTP) protection, and key-lock function.
  • USB and LXI compliant LAN interfaces, optional GPIB.
  • LabVIEWTM, IVI-C, and IVI.NET drivers provided.
  • Remote PC control software available.
