Programmable Triple Output DC Power Supplies

B&K Precision introduced its latest programmable triple output DC power supplies, the 9130B Series. The new linear triple output power supply line offers three isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current. Each model in the series offers a different configuration of variable output voltage and current on two channels: 0-30V, 0-3A (9130B); 0-30 V, 0-6 A (9131B); and 0-60 V, 0-3A (9132B). The third channel output is rated at 0-5 V, 0-3 A for all models. With a compact 19" half-rack form factor and fully programmable outputs, these DC power supplies are practical tools for use in a variety of applications including production testing, automated test, and circuit design.

Triple output power supplies give users the flexibility to configure multiple channels to meet their application needs. Each output can be used independently or connected in series or parallel with other channels. This allows for various output configurations such as positive and negative outputs for powering bipolar circuits and devices.

All models in the 9130B Series feature high programming and readback resolution of 1 mV, 1 mA with low noise and excellent load regulation. Additionally, each model provides constant voltage (CV) and constant current (CC) modes, a bright vacuum fluorescent display (VFD) indicating each channel output concurrently, and convenient cursor keys with rotary control knob for precise voltage and current settings.

Flexible series and parallel combination modes on the 9130B Series allow users to conveniently meter channels connected in series or parallel. Tracking mode is also available for maintaining a user-defined ratio between outputs, which allows for easy simultaneous adjustments across multiple channels.

The rear panel offers output terminals with remote sense connections and standard USB (USBTMC-compliant), RS232, and GPIB interfaces supporting SCPI commands for remote programming. Users can easily control their instrument, generate test sequences, and log data via the provided PC software or NI-certified LabVIEW driver.

Other features include a timer-controlled output function along with internal memory to store and recall up to 36 different instrument settings. All three models offer built-in overvoltage protection (OVP), overtemperature protection (OTP), and keylock function.

Available immediately, B&K Precision's 9130B Series models are all backed by a standard 3-year warranty and listed at the following prices:
