Three isolated output channels each produce

100 W of clean power with low ripple and noise

characteristics. Combining all three channels increases the maximum power output to 300 W. Multiple outputs paired with advanced list mode programming, data logging, and protection features make these power supplies suitable for a wide range of benchtop or test system applications. Powerful list mode programming functions enable users to set up and execute complex test sequences directly from the front panel. Individual list programs can be assigned to one or multiple output channels and executed simultaneously or sequentially. Additional list mode features include triggering capabilities for synchronizing outputs or external instruments, and the ability to save/ recall list programs using an external flash drive connected to the USB host port. The USB host port is also used for logging voltage and current data to a flash drive at adjustable sampling intervals. This series provides system integrators with a LXI compliant LAN, USB (USBTMC-compliant), and optional GPIB interface for remote control and programming. The provided LabVIEWTM, IVI-C, and IVI.NET drivers further simplify system development and integration. In addition to OVP , OCP , and OTP protections, these power supplies support remote inhibit and voltage fault features to protect both the device under test (DUT) and the power supply.

Triple Output Multi-Range DC Power Supplies bkprecision.com Highly Configurable Test Sequence Generation To help control inrush current, the voltage slew rate is adjustable from 0.005 V/ms to 3.2 V/ms. The current slew rate is also adjustable from 1 mA/ms to 1000 mA/ms. Dwell or step duration can be set from 0.1 s to 9999 s. BOST / EOST (Beginning / End of Step Trigger) can be enabled for any step in the list to generate output triggers for synchronizing events with other externally connected instruments. At the end of a list program, the termination behavior can be set to a constant DC value, remain at the last programmed list step value, or run another user-configurable list program. Advanced list mode The 9140 series list mode programming features are useful for repetitive testing or other applications requiring a specific sequence of voltage and current settings. Further expanding test sequence capabilities, list mode programs work with channel combine, coupling, and on/off delay features for highly configurable and customizable testing sequences. The illustration below highlights some of the configurable options for setting up a list mode program. Extended list mode functionality Each list mode program contains up to 100 steps each. Step parameters can be configured from the front panel or on a computer and loaded into the power supply's internal memory. List memory is shared across all three channels, providing the capability to reference and run the same list or different lists simultaneously.

The 9140 Series multi-range power supplies extend rated power from one point to a curve, delivering 100 W per channel across a wider range of voltage/current combinations. Channel coupling Output sequencing Channel coupling links the output states between multiple channels. ON/OFF output delays for each channel can be set from zero delay to 1 hour in 0.1 s increments Microcontrollers and other processing devices often require specific startup power sequences in order to function properly. The 9140 Series' coupling mode, output delays, and slew rate can be configured to produce power up sequences for microcontroller testing applications. ON delay CH 1 CH 2

Triple Output Multi-Range DC Power Supplies bkprecision.com The tools you need: on the bench or in the rack Output monitoring These power supplies offer a graphical display mode display mode to visually monitor and observe measured voltage and current data on all three channels. Direct data logging Log voltage, current, or both at a user-defined sampling interval adjustable from 0.2 seconds to 5 minutes directly to an external USB flash drive. Data points for all three channels are saved as a CSV file with date and time stamp. Comprehensive protection and security Overvoltage (OVP), overcurrent (OCP), overtemperature (OTW/OTP) features help protect the power supply and DUT. The overtemperature warning (OTW) provides an additional layer of safety before the protection is triggered and the output is disabled. Other protection features include key-lock protection and remote inhibit, allowing the output to be disabled if fault conditions are met. The Kensington security slot in the rear panel helps prevent theft. Test system integration
