BK Precision 9140 Series Vs GPP4323
« on: November 17, 2023, 12:11:00 pm »
Hey everyone,

I'm in the process of selecting a new power supply for my lab and I'm currently torn between the BK Precision 9140 and the GPP-4323 models.

While the price difference is significant, the BK Precision 9140 series stands out to me with its compact 2U size, which is a perfect fit for my limited lab space. However, it only has 3 channels.

On the other hand, the GPP-4323 offers four tunable channels with CC and can also function as a DC load, providing additional versatility.

If cost isn't a limiting factor, which one would you recommend? Also, any insights on the perceived quality of BK Precision versus GW Instek? I'd appreciate your thoughts and experiences.

No hands on experience but possible the fan noise may be higher on a smaller unit. I also get the feeling the BK Precision 9140 is a switching PSU while the GPP4323 is a linear PSU for sure. For developing / testing analog circuits you will want a linear PSU because a switching PSU pushes too much noise into the circuit under test.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
