Hello,
I am new here and a newbie diy'er. I did a search, but have not found an anwer to the following question.
I just pulled some parts from an old UPS system (circa 1993) including a few Arcol Aluminum encased power resistors with cable terminations. I looked them up but was unable to find their specific model number. They resemble the current HS series and measure similarly to a HS50 although the top of the body is square rather than round.
Can anyone here identify it's power rating?
On the front:
ARCOL 90.51 (could be an I instead of a 1)
A118-3/15R =/-5%
Thanks,
Gary

Hi,
if it's a similar size to the HS50 then it probably has a similar power rating.
However, continuous power dissipation at the maximum rating will need a big or a fanned heatsink.
