Voltage compliance issues

[Alexterrell]

Hi there,

The European Union introduced loads of regulations for Low voltage, but
then defines this as 75V - 1000V DC.

I'm working on a product that runs off 4.5 - 7.5 volts, powered by a
transformer or switch mode power supply. Obviously the transformer /
switchmode power supply needs to be approved and meet standards.

Can some one tell me if there are electical standards relating to
products running at 4.5 to 7.5 volts?

Thanks

Alex

If you had a battery operated device, you would not need to comply with this directive.

Since you have a power supply and it will have an input voltage of 220VAC, you must comply with the directive. However, only the power supply must comply with the directive not the device that is running with 4.5 to 7.5v.
