How do you manage power amperage for your sim

[kurt-olsson]

Hm... A small problem here.

Around 100 Korrys each 80-100ma ~ 8amps
Backlight will be total of around 25-30 panels each around 200-500ma. ~ 8-15 amps
Computers 4-5 amps

I have a fuse that takes 10amps before cutting out.


What max kw draw do you have and how did you solve this issue?

My outlet is 220V * 10 Amps = 2200kw

Korrys example is 24V * (0,08A * 103) = 197kw
Backlight 5V * (~0,5A * 25 panels) = 62kw

If all stuff added, i might hit max kw.

I had my electrician wire two 20 amp service outlets (110vac) that my systems plug into.

I use a UPS on the one circuit and all computers are driven by that. All other electrical needs via direct plug in at the wall with a power strip.

The current drawn from the mains supply will be much lower than the DC current load across your supply.
For example your 8amps @24v  works out to approx 192 watts,  divide that by the 220v input and you are less than 1amp.  Add 15% for the power supply efficency rating and you are somehere in the ballpark.
I measured one of my supplies the other day, 26 amps at 28v DC load.   This was only drawing 2.5A from the AC supply.

Rob would be a good one to advise how much load for all real panels & Korries
His would draw more AC current though, as he will be running on 110v

Thanks for your replies, very interesting reading.
Ive seen from Robs Youtube video that his setup draws 30amps on 5V = 150kw. So i can use his measure as a guidence.

With my calculations i should be fine with an 10Amp fuse with 220AC.

I will be on the lookout for ampmeter gauges so i can monitor my amp readings.

I think you need to check your math. 30 * 5 is 150W, not kW.

150kW is a lot of power.

For reference a house in North America (120V) with 200 Amp service for the entire house....that breaker trips off at 24kW.

In case there is confusion on the notation:
k - is a scale of measurement meaning x1000
W is the unit of measurement, in this case Watts, a measurement of power.
150,000 Watts = 150kW
1,500 Watts = 1.5kW
150 Watts = 150W

i started out with 225 amps and now  have 500 amps coming in broken out to brk boxes .. plus i hace AC  power running alot of stuff last thing i want is failures but this is tx andbevrrything is big   lol

[jackpilot]

but this is TX and everything is big   lol

we already knew but nice of you to pinpoint it!!

This is very very true, my bad.
