From: Hammy on 17 Jul 2010 09:36 What is something cheap and simple that can be used to dissapate 300W on a 200Vdc bus. I'm trying to think of something I could maybe pick up at a local homedepot or similiar. I need a 300W load to test out my PFC.

Two in series and then as many of those in parallel as needed. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam. Use another domain or send PM.

Two in series and then as many of those in parallel as needed. Sounds good one 60W bulb is about 200 ohms.I'll look around for some small cheap bulb mounts.

Maybe two or three electric irons in parallel. If this will be anything other than a temporary lashup, you'll want a fuse rated to interrupt 200VDC.
