hi guy
i have a problem with this type of alim. i suppose the printer dont turn on
i disassemble a alim. and i saw i connector with 3 pin gnd + 3v + Vo
this vo = is 24v ????

thankz at all

 

Welcome to AAC!
Why would an alim be interested in circuits?
Are you referring to one of these?

 

yea is mine board schematic , i want know if put out gnd + vh = 3v and Vo= ???? 3 pin out

 

According to that schematic I reckon the output voltage should be about 24.7V or 7.0V on the 'VH' pin, depending on the control voltage applied to the centre pin of the connector. An input of 3V on the centre pin would give the 24.7V output. The other pin is a GND connection.

 

ok thankz so much
