Programmable Triple-Output DC Power Supplies with isolated Outputs
09 November 2015 - B&K Precision introduced a new programmable triple output DC power supply, the 9129B. The new linear power supply features three isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current. The 9129B provides two channels with variable voltage and current up to 30 V/3 A and a third variable channel rated for 5 V/3 A. With a compact 19" half-rack form factor and fully programmable outputs, the 9129B is offered at an economical price point.
Featuring a programming and readback resolution of 10 mV/1 mA, the 9129B provides convenient cursor keys and a rotary control knob for precise voltage and current settings. The power supply can be operated in constant voltage (CV) and constant current (CC) modes. Each channel output is simultaneously displayed on a bright vacuum fluorescent display (VFD).
Flexible series and parallel combination modes on the 9129B allow users to conveniently meter channels 1 and 2 connected in series or parallel. Tracking mode is also available for maintaining a user-defined ratio between the outputs, which allows for easy simultaneous adjustments.
Provided on the rear is a USB-to-TTL interface supporting SCPI commands for remote programming. A USB-to-TTL serial adapter and USB cable is included with the instrument. Users can also control their instrument, generate test sequences, and log measurement data via the provided PC software application or NI-certified LabVIEW driver.
Other features include built-in overvoltage protection (OVP), overtemperature protection (OTP), keylock function, and internal memory to store and recall up to 27 different instrument settings.
Available immediately, B&K Precision's 9129B is backed by a standard 3-year warranty and listed at a price of $695.
