This 5V DC 1A USB power supply comes complete with a Micro USB output lead and a set of AC interchangeable AC pins. The PSU has a 90-264V AC input for world use. It carries full international safety approvals and meet the latest ErP stage 2 requirements with high reliability (M.T.B.F of 50K hours at 25 degrees C.) The SW4149-B power supply can be used to charge a wide range of products.
We are dealing with partially sighted or blind listeners, who have players with external power supplies. Because of their difficulties, they sometime manage to break the wires from the PSU, or the PSU gives up. Unfortunately the replacements from the player supplier have changed and they are costing us nearly twice as much; particularly as we have to buy a USB to 1.3 mm lead.
Buying the 85-2890 means a small soldering job to fit a 1.3mm, but saves the Talking Newspaper several pounds on each occasion.
