Two things wrong with the Samlex SEC-1235M

The Samlex SEC-1235M is a well priced and performing switchmode power supply. Two things have been bugging me though - the lack of Anderson Powerpole output and the loud fan.

AD5X wrote a comprehensive review of the power supply[1], in which he addressed the fan issue by including a 100 ohm resistor in the fan circuit. I performed the same modification and now the fan is not audible over the ambient noise. A bit of time with a multitool to cut out an opening for a panel mount Powerpole housing and it’s good to go.

Now I can’t really think of anything wrong with the SEC-1235M.
