BK Precision - BK1786B Software

Introduction to the BK1786B

I recently acquired a BK Precision programmable power supply [External] BK Precision programmable power supply, type BK1786B. This is a DC power supply which can output voltages between 0 and 32 VDC, with an output current of up to 3 A.

The supply unit is completely digital and programmable: you can enter the desired voltage/current configuration by entering the values on a numeric keypad. You can enter values with a resolution of 10 mV/10 mA so it is quite accurate.

This kind of units is especially interesting for labo experiments, where you slowly need to increase the voltage between 0 and ... V. Of course there are so many other applications where you could use a programmable supply.

The BK1786B comes with an RS-232 connection, meaning you can connect to it with a computer. It comes with some software you can use to view, change, log the outputs. You can also setup testing programs for hardware.

The communication protocol is described in the manual: it describes everything you need to know to create your own software for the power unit. So I decided to try making my own applications for the BK1786B...

My software applications

Here you can view a list with software applications I developed for my BK unit.

My hardware applications

I have designed my own hardware add-on for my BK power supply. This hardware contains a PIC microcontroller that will communicate with the power supply. In the example code a LED is activated when the current limit is reached. View the complete project.
