BK Precision 1697 construction comment/ question — Looking from the front towards the back of the 1697, two heat sinks are lined up along the right border of the circuit board. Another heat sink is towards the center rear of the board. The exhaust fan is towards the right side on the back. Now, the cover has three vents, two on the left and one on the right. If the cover were to be rotated 180 deg, the two vents would align with the two heat sinks. Did someone at BK P goof and the production mgmt decided to use the misformed covers anyway?
Need some troubleshooting help ideas – I have 2 BK Precision 1697 (circa ~2010?) units with the same problem. Both max out at 22V even though the [shift] [0] over Voltage limit displays 40.0V. Neither unit had been pushing current or potential limits when this problem developed, and neither have seen more than light use. Any ideas?
Any idea what kind of chip was used for the user interface? You complain about the shift key being needed for just about everything. Now I notice it has 16 buttons, which is a suspiciously 'digital' number. Could it be that their IO chip can only scan 16 buttons? And more capable chips were not available for some reason? So if you want separate buttons for voltage and current, you have to give up something else. Sometimes UI design is just as hard and constrained as EE. 🙂
Hey buddy, I am working in an electronics factory in Thailand and up to now I had the "feeling" that BK Precision is a local company, due to the fact that when I compare BKP tools we have here with other brands, like Agilent, Tektronix, etc, the BKP thingies always come last, so somehow I associated them with "local manufacturing" (in my narrow mind till now, BK=Bangkok). Now when you said they are Canadian, I looked on the web and found they are in fact… American. So, it happens to tougher guys too :P, hehe… BTW, good work here! (it is not for every blog I watch that I scroll down to look to their 9 years old videos, hehe, but right now I am quite curious to see the other three to see what will you do when you finish the fingers of both hands… :P:P).
That's nice, but I think for that price I'll still to making my own power supplies, even though I'll probably never be able to make a nice switch-mode one, way to many complicated "math-u-lations" and formulas.
Hi, electronic guru !
I'm going to buy a rigol ads1102 and I'd like to test my little lab power supply for ripple and so on. Could you tell me the connecting procedure and scope setting to do this? Really really thanks in advance.
oh my god that oscilloscope looks amazing , and WHAT !!! it's only 415$cad free shipping OMG !!!! this is so much better than my 40 years old HP oscilloscope
@chukchee Hmm, after thinking about this for a second he may have seen CA in print and assumed it was for Canada and not California, but you are right, they are in Yorba Linda California
Phenolic is fairly typical in supplies like this, so I wasn't going to mark it down for that.
The soldering was fine.
Yes, not the world's best construction board support etc, but adequate for a low end bench supply.
It's actually quite low priced for a PC controlled PSU.
A $330(US) switchmode bench supply gets a pass for using single-sided phenolic PCB? At that price, I'd expect at least FR4. Traces develop microfractures much more easily on phenolic than FR4.
Some of the soldering and lead trimming looked horrible. The vertical boards looked poorly supported. How was the solder work on the bottom of the main board?
On the plus side, the features were good to hear about, and thanks for the detailed spec checkout.
Thank you this video saved my day at work
I’m American and you sound like the British queen gay love lover.

Rebranded Manson, rebranded like almost every BK Precision product.

I was think about get some equipment from BK Prescision. Are they good?
there was an overshoot present, what was your overshoot voltage? What was the V/div on your scope? Would be good to know, you know matey!
why you never showing computer control part of PSU-s?
B&K Precision not canadian company! BK is US company.

Hmm … power supplies are evil .
you void the warranty, never recommend anyone to take the cover out lol

Are you sure they're Canadian? Aren't they in California?
