    RS switch mode power supply

    Hi Guys, Has anyone come across this SMPS from RS, 445-107. Blurb says its class 1, because it has an earth pin. I cannot get a circuit from the earth pin to the '-' of the output. I have sent RS a question about this but have not had a reply. Must fail it as a class 1 appliance.
