schematic of a 305D ... any mod suggestions?
Honestly not sure if it was from the drop or not...
Since the volts reading is stable it suggests the output current is also stable but the meter is faulted, likely the IC itself in the module.To confirm this, attach a good ammeter to the output and adjust the current. You should see the good ammeter read linearly as you adjust up and down while the PSU ammeter reads all over the place. Short circuit the output, and the CC LED should light, a final note that the current module is working by testing the short circuit protection.If the above works, then its easiest to replace the ammeter module rather than repairing it.Quote from: alex27riva on November 28, 2014, 07:40:06 pmHi, how can i fix this problem?
