Hi Tim,
Out of interest, are there (no doubt pricey) bits of test kit that
will induce the dialed-up load?
There probably is Ralph but I think were entering into the realms of
expensive and serious testing kit which probably requires a degree of
something or other to operate....................
Yes, I agree, probably too pricey for your one-off need, that's why I
only asked out of interest and not as a solution for you. Perhaps
companies that would find them handy, like UPS makers, can easily knock
up their own as required so there's no market.
Cheers, Ralph.
Stage lighting equipment would probably do, along with a meter.
(Perhaps an Arduino outputting DMX-512 and measuring the current used
if you wanted to be accurate about it.)
The dimmer packs I've used can dim 10 Amps per channel, in 256
dimming steps, and the follow-spots have their own dimmer, along with
a 1.2kW bulb.
Either way that is a lot of light and heat you'll be generating...
Any thoughts as to where you'll put it? :)
I picked up the meter this afternoon, I have a 500w spot light so I
will have a play with that and maybe get another 500w spot light to
give me a 1000w to test with.
Just an update of how thing went, I used two 500w halogen spotlights to
act as load on the UPS this gave me a load of 34%. The lights ran for
about 15 minutes (never made a note when I turned the power off) before
the battery died. The battery was recharging when I left so I will have
to wait till after the weekend to see the results (at least the battery
indicator light was not flashing).
Thanks for all the advice
