9129B

Data Sheet Triple Output Programmable DC Power Supply Model 9129B The 9129B is an economical triple output linear programmable DC power supply featuring isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current. Additionally, this supply 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 control the 9129B, execute test sequences or log measurements using the provided PC software application. 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. This power supply is suitable for a wide range of applications including education, service and electronic design. Features ■ 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 Output Rating ■ Voltage 0 - 30 V (CH1 & CH2) 0 - 5 V (CH3) Current 0-3 A (CH1, CH2 & CH3) Softpanel for remote control, test sequence generation, and datalogging available ■ Overvoltage (OVP) and overtemperature (OTP) protection including keylock function ■ Compact 19” half-rack form factor allows for side-by-side rack mounting of two units Technical data subject to change © B&K Precision Corp. 2021 www.bkprecision.com Triple Output Programmable DC Power Supply Model 9129B Front panel Bright vacuum fluorescent display indicates voltage and current for each output simultaneously Numeric keypad for direct entry of voltage and current values Function keys Cursor keys Rotary knob CH1, CH2, and CH3 Outputs Rear panel Thermostatically controlled cooling fan AC line input TTL interface 2 Line voltage selector Fuse box www.bkprecision.com Triple Output Programmable DC Power Supply Model 9129B Flexible operation Combined series mode 60.00V SE r 3.000A  5.00V 3.000A Channels 1 and 2 can be wired in series to increase the voltage. Selecting series combined mode provides convenient metering of the channels connected in series. Combined parallel mode 30.00V PA rA 5.00V 6.000A 3.000A  Channels 1 and 2 can be wired in parallel to increase the current. Selecting parallel combined mode provides convenient metering of the channels connected in parallel. Tracking mode 30.00V 30.00V 5.00V 3.000A 3.000A 3.000A  Tracking mode can be used to simplify adjustments across multiple channels by maintaining a user-defined ratio between outputs. Tracking mode can be set on channels 1 and 2. Application software Bipolar output configuration The independent and isolated outputs can be used to create positive and negative outputs between channels 1 and 2. +VDC + Channel 2 OVDC PC software is provided for front panel emulation, generating and executing test sequences or logging measurement data without the need to write source code. ■ Dashboard for LabVIEW apps. ■ Channel 1 Remote monitoring on iOS, Android, or Windows 8 compatible tablets or smartphones via NI Data -VDC Log voltage, current, and power values of each channel as well as timestamp, CV/CC mode, and output status. ■ Quickly develop a custom dashboard with indicators, charts, or gauges to monitor your power supply. ■ Create an unlimited number of external list files to be executed from PC memory.
