B&K Precision Model 9129B Triple Output Programmable DC Power Supply

B&K Precision model 9129B is an economical triple output linear programmable DC power supply. It features isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current. The 9129B can operate in tracking mode with user-configurable ratios between channels. The front panel keys and rotary knob, with convenient cursors, let users quickly set voltage and current values. Up to 27 different instrument settings can be saved and recalled. The power-on state of the outputs can also be configured.
The USB to TTL interface supporting SCPI commands can be used to remotely control the power supply via a PC. Alternatively, users can use the provided PC software application to control the 9129B, execute test sequences or log measurements. This software also integrates with Data Dashboard for LabVIEW
apps (enabling iOS, Android or Windows 8 compatible tablets or smartphones to remotely monitor select measurement indicators).

Features and Benefits

Three independent and electrically isolated outputs
Displays voltage and current settings for all three channels simultaneously
Low noise, linear regulation
Series and parallel modes combine channels to increase the output voltage or current
Tracking mode allows users to set up channels to maintain a programmed ratio
Fully programmable channels with Output On/Off control
Store and recall up to 27 instrument settings
Communicate via USB interface supporting
SCPI commands using the included USB to TTL serial adapter
Overvoltage (OVP) and overtemperature (OTP) protection including keylock function
Compact 19 in half-rack form factor allows for side-by-side rack mounting of two units
