B&K PRECISION DC

B&K Precision is a manufacturer of test and measurement instruments, including DC power supplies, with a history dating back to the 1940s. The company is known for producing benchtop and programmable power supplies used in engineering labs, production test, and repair facilities. 3G Electric supplies a range of B&K Precision DC power supplies, focusing on multi-range and dual-range models that offer flexibility in voltage and current output. These units are designed for applications requiring precise voltage and current regulation, with specifications such as load regulation of 0.01% + 3 mA and line regulation of 0.01% + 2 mV on certain models. The power supplies feature LED or LCD displays, and many include NIST-traceable calibration certificates. Enclosures vary from compact 1.75-inch-high rackmount units to larger 5.1-inch-high benchtop models, with dimensions accommodating standard 19-inch racks. Input power is via AC power cords or USB cables, depending on the model. The product line includes multi-range supplies like the 9240 and 9201B, which can automatically adjust voltage and current limits within a given power envelope, and dual-range supplies such as the 9172B and 9183B, which offer two output ranges for different load requirements. These instruments are suitable for powering circuits, testing components, and simulating battery conditions in R&D, manufacturing, and service environments. 3G Electric provides global logistics support, ensuring that these power supplies are available for procurement with datasheets and technical documentation to assist engineers in selecting the appropriate model for their specific test setup.

Frequently asked questions

Common questions about B&K PRECISION DC from 3G Electric.

What is the difference between multi-range and dual-range B&K Precision DC power supplies?

Multi-range B&K Precision DC power supplies, such as the 9240, automatically adjust the voltage and current limits within a constant power envelope, allowing a single unit to cover a wide range of output combinations. Dual-range models, like the 9172B, offer two distinct output ranges (e.g., high voltage/low current and low voltage/high current) that the user selects manually. Multi-range supplies provide more flexibility for varying loads, while dual-range supplies are simpler for applications with two common operating points.

Do B&K Precision DC power supplies come with NIST calibration?

Yes, many B&K Precision DC power supplies supplied by 3G Electric include NIST-traceable calibration certificates. This is indicated in the product specifications, such as for models 9240, 9182B, and 9201B. NIST certification ensures that the output voltage and current measurements are traceable to national standards, which is important for quality assurance and compliance in regulated industries.

What are the typical load regulation specifications for B&K Precision DC power supplies?

Load regulation for B&K Precision DC power supplies varies by model. For example, the multi-range 9240 has a load regulation of 0.01% + 3 mA for current and 0.01% + 3 mV for voltage. Dual-range models like the 9172B specify load regulation of less than or equal to 0.01% + 250 µA for current and less than or equal to 0.01% + 1 mV for voltage. These tight tolerances ensure stable output under changing load conditions.

Can B&K Precision DC power supplies be rack-mounted?

Yes, certain B&K Precision DC power supplies are designed for rackmount installation. For instance, the 9115B model includes a rackmount kit and has a 1.75-inch height, fitting standard 19-inch racks. Other models, like the 9240, have a 3.5-inch height and may be used in benchtop or rack configurations with optional accessories. Check the product specifications for rackmount compatibility.

What interfaces are available on B&K Precision DC power supplies for remote control?

B&K Precision DC power supplies offer various interfaces depending on the model. The 9241-GPIB includes a GPIB interface for remote programming. Many dual-range models, such as the 9172B and 9183B, come with USB cables (Type A to Type B) for PC connectivity. Some units also support RS-232 or Ethernet options. Refer to the datasheet for specific interface capabilities.
