HelloYou need to convert the voltage 190-250 DC to DC voltage of 380 volts, the current is 0.5 A.How to do this on a product powerint?Require mandatory isolation transformer.Thanks
Unfortunately we do not have any reference design available as of now for the isolated version. Could you please give some details about your application. We will see if we can suggest something.
We use the source shown in Fig.But it has low reliability at startup. They wanted to replace the source of your production.Required parameters:Input voltage 220DC +10% -15% output voltage:+24 V 2A-24V 2A400 V 0.4 AWe are considering the installation of 2 power supplies 1 to 24 and -24, one for 400V (+ -15%)thanks
You can use the following devices
1. LCS701HG/LG for 220V DC to 400V DC conversion and
2. TOP268VG/EG for +24V, -24V output.
Thank you.Can I take a design for RDK-239 and powered it postoyanke 220V circuit before removing the diode bridge BR1 (GBU806), or you need something else to replace it?
You can use the RDK -239 design for reference. But you have to modify the design according to your requirements. You can start the design with the help of PIxls. You can download the PIxls designer for free at following location
This consists of PIExpert and PIxls. You can Use PIxls for your design
If you need any design help contact one of our FAE's in geographical region. Please find our sales offices at following location
I think you can HiperPFS + HiperTFS duo for your application.
