Hi Guys,

From the 400v DC, 80W o/p source I want to measure the power whether it provides the accurate 80W. How can I test it. is it possible with multimeter or any other technique.

 

yes u can do it via multimeter,

Power = volt x current

put a load of 0.2 Amps on the source & read the voltage across the load
e.g
power = 0.2 x 400
power = 80w
 

Dear if u don't have any load of 0.2A then u can connect a resistance of 2kohm at the output side for the purpose of 0.2A load.
But resistance should not be less than of 80W.


Thnaks & Regards
