The B&K Precision 9129B is a versatile, programmable DC power supply with three independently controllable and electrically isolated outputs. It is ideal for laboratories, development departments, training centers and service applications. Thanks to its flexible combination options in series and parallel operation, higher voltages or currents can be achieved. With the tracking function, user-defined voltage ratios between channels can be set and kept stable.
The device enables convenient operation via front buttons and rotary controls, offers memory options for up to 27 device settings and has comprehensive protection functions. With the supplied USB-to-TTL adapter, the power supply can be easily controlled via PC - even mobile via LabVIEW Dashboard apps for iOS, Android or Windows.
