DC power supply with three isolated outputs
B&K Precision's 9129B triple output dc power supply features three isolated outputs that can be adjusted independently or combined in series or parallel to output higher voltage or current and has overvoltage and overtemperature protection.
B&K Precision's 9129B triple output dc 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. It has a 19-in. half-rack form factor and fully programmable outputs and 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. 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.
