Re: [PSES] interesting recall by CPSC

Doubt that safety required highest setting. So we called the two settings 'safe' and 'explode' for what the parts did when the plug was inserted. It failed safe as required. The customer called it dead on arrival and sent it back. Warranty costs provided a motivation for setting to the higher

Re: [PSES] interesting recall by CPSC

Why is the product called Dual-Voltage? Obviously it is a auto voltage from 100 to 240 Vac so there is no mis-placed to 110 V when used in 230 V countries. I have learnt some safety standards require the voltage setting to the highest before leaving the factory. It seems to look after such fores

The CPSC has issued a re-call for this "Dual-Voltage" unit for causing fires at 220V . But the rating label indicates an input rating of '100-240'. Also looks like the unit is Class II construction, and that each component is individually powered. Label image here
