Universal Regulated 600mA AC/DC Power Adaptor (OR-AD600)
on 11 December 2014
Universal Regulated 600mA AC/DC Adaptor Power (OR-AD600) - Arrived very quickly indeed, so FULL MARKS to the seller for that.
However, please note that this is a "Switch Mode" power supply, rather than the traditional "linear' power supply.
I bought this to replace a power supply for a small high quality audio system that I had removed to power some Christmas decorations. Once I connected the power supply, a great deal of radio interference was caused to the radio section of the hi-fi and to nearby radios, making it unsuitable for use on audio and radio systems and perhaps electronic musical instruments.
Unfortunately cheap "switch mode" power supplies and chargers (that tend to be supplied with most gadgets these days), are poorly designed,omitting the necessary suppression components for low cost. This can cause all sorts of noise problems for audio and radio systems.
I therefore moved the original 'linear' power supply back to the audio system and used this power supply on the Christmas decoration. It certainly does power the Christmas decoration well but, of course, causes noise and interference to nearby radios.
To conclude; Super speedy service from the seller - excellent. The power supply itself is suitable for low power lights and decorations but, as with all 'switch mode' power supplies, I would not recommend use on audio systems and definitely do not use a switch mode power supply to power portable radios. Get a good linear power supply.
