Please note: Prior to use, please be sure that it is an AC output supply that you require for your use. Most consumer electronics devices use a DC current for power. If you are in any doubt, please consult a member of staff for further information. Using an AC output adapter on an appliance that requires a DC current may cause permanent and irreversible damage to your equipment. Maplin Electronics accepts no responsibility for damage caused to equipment by using the wrong type of power supply.

Rated 1 out of 5 by from Confusing I ordered what I was hoping to be a fixed 12V AC transformer. However, the product turns out to be a dual-voltage 12 and 18 V unit, with no instructions as to how to switch between the two outputs, and no explanation about the co-axial connector on the housing. Only a time-consuming effort to contact the OEM resulted in the necessary information; it turns out that the equipment would not be CE-compliant unless it had two outputs: The fixed cord is the 12V/3A output, and the socket carries the 18V/0.5A output.

Rated 4 out of 5 by from Fine Installed 2 days ago .. powers my equipment successfully without emitting too much heat. Arrived 48 hours after placing order .. packaging could have been better and needs attention.

Rated 3 out of 5 by from Bulky It did the job, but it is very bulky and very heavy. I think the reason is that is trying to be more than one things at the same time, but this is not a item you can neatly hide behind your hi fi unit.

Hi there Could you advise if the output is centre positive or negative. I'll need the former. Cheers

This is an AC to AC adapter so there is no polarity.

On this occasion Maplin do not stock a product that exactly meets your requirements, or indeed anything close enough to offer you as an alternative.
