Using a MOSFET circuit design and high quality components with very low temperature coefficients, the power supply is extremely stable and capable of outputting current as low as 1 mA with a 100 uA settable resolution. This power supply was designed for electrical and electronics applications requiring precise levels of low current, including 4-20 mA current loop testing, calibration, or basic IC testing.

• Low 1 mA settable current limit with 0.1 mA resolution
• Output on/off button
• Exceptionally low current ripple and noise (<0.4 mArms)
• Excellent regulation
• Constant voltage (CV) and constant current (CC) operation
• Two large, easy-to-read LED displays provide good visibility in bright or low light conditions
• CV and CC mode indicator
• Automatic recall of saved voltage and current settings upon power-up
• RS-232 interface
• Isolated output
• Overload and reverse polarity protection
• Power-on self test
• Model 1739 B&K Precision

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.

• 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
• 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
• Suitable for a wide range of applications including education, service and electronic design
• Model 9129B B&K Precision
