Hi All,
I have a Makita DC10WD charger (US version) that I opened up to figure out how to convert it to 230V (actually doesn't need any work except the mains plug )
During the "reverse engineering" i tried to do I encountered a device with "funny" (custom?) marking - according to its connections it seems to be the flyback controller, its in a SOT23-6 (or similar) package and as you can see marked with a (rather unique according to my experience and web search) 72-63-22 marking.
from measurement it is a 65kHz device.
out of curiosity...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

Re: 150d bench power supply ammeter not working
You can use an isolated DC/DC converter such as this one:

(there are many options from different manufacturers - make sure you match the input range from your rectified 22V supply and output voltage and power that your displays need)Re: 150d bench power supply ammeter ...from different

Hi All,
Ran from Givatayim Israel,
EE by education and heart .
During the day I usually work on some wireless technology, and, when night comes, I try to repair our failing home appliances etc. (with modest success...) as well as work on some personal electronics projects.
thanks for a great forum!
