What are the parameters of this resistor?

Hi,

I attach a picture about two resistors. I don't know neither their value in ohms nor their wattage. Does anyone know how to identify them according to the mark on it? Is there a way to replace them since they are open, and I don't where to buy them.

Google is your friend!

Often if you just put all of the text you can find on a component into a search engine you will find something useful on the first page or so of results. Even if you only gleen a manufacturer's name, that can be a lot.

In this case, Googling: KRAH-RWI 27/07 D VHPR 60 V 11R75K

Returned many hits. The first one was an Amazon listing for a part number that appears different, but probably related. This may give you an idea of where to buy them.

But the fifth entry was for "Encapsulated high power resistors - KRAH" with a link to the company's website.

http://www.krah-gruppe.de/modules.php?name=Produkte&op=anzpro&kat=gekapselt&newlang=English

That page has their product line and the third one was the VHPR 60 -500 and a description that identifies this as a 60 W High-power resistor in a metal casing.

Following the link to the data sheet:

http://www.krah-gruppe.de/media/datenblaetter/Datenblatt VHPR 60-500 mit Ueberlastfaktor Stand 12 2013.pdf

Based on the information in there, this would appear to be an 11 Ω 60 W resistor intended for vertical mounting, possibly with a 10% tolerance and 77 ppm/K temperature coefficient, although the order designation is a bit iffy on those last two points.
