Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Open one up and take a look.
It could well be based around a UC3907 or just a common voltage reference

It's not not possible to permanently lower current.

It is possible to control the current limit while the device is operating
by continually sending a canbus message that sets the output current limit.

wronger than a phone book full of wrong phone numbers

Just registered to say thank you to poida for posting the explanation on how to set the voltage using the CAN bus. Thanks a lot!
