I have a question about the input voltage of ALTAIR04 IN eDesign

I want to design with ALTAIR04 in the software, but the input voltage must be less than 350V, I want to know that 

 it means ALTAIR04 can’t be designed in a input of 440V AC?, or it’s only the limit of the software ?

Hi Peter,

first of all thanks for your interest in eDesignStudio.

Up to now, ALTAIR04-900 design on eDesignStudio supports input voltage lower than 350V, but we are working so that it can sustain ultra wide-range operations. You'll find this updating in next release.

Meanwhile, you can check application note AN3290 (http://www.st.com/internet/com/TECHNICAL_RESOURCES/TECHNICAL_LITERATURE/APPLICATION_NOTE/CD00286662.pdf), where, at page 29, it's described how to modify standard schematic, as that provided by eDS, so that it can sustain even greater input voltages.

Best regards,

eDesignStudio team member

I have seen the application note, expect the updated software
