Do you still need a solution? 480W custom $2/W is not unreasonable. What load type is this Resistive, Capacitive or ?
With a 80/6 ~13 ohm load a 6,000 uF cap will discharge in 13*6m= 48 ms where it decays 63%. NG.
> this is a 63 Ah battery and I am burning 4 x 10A LED, does that mean this thing will only run for an hour and a half?
DC 36V/48V Step Down to 12V 20A 240W DC DC
No. But it does mean one 12Vout converter can only power 2 Lamps
A total power of 480W out load might need 530W input or so to...
BC Hydro had some suggestions
Here are some of the first things you should check for low p.f.
- Check if you have any rack-mounted film caps rated for xx kVARs
- Large fans and motors only partially loaded have low pf.
- Equipment with a high number of transformers (such as lighting ballasts)...
We can only guess unless you tell use the model (link to specs and your brown-out levels and qualification test results. You cannot guess without testing them.
The max current of 4A is quite low for high-quality batteries. This limits the I^2R=P power dissipate and R is the sum of each cell ESR or Rs which rises rapidly below 10% charge (SoC).
The power capacity W=VI and voltage drop at max load depend on the above parameters.
Battery cells are like...
All mechanical structures will have at least one resonant frequency in each axis depending. The stiffness must raise the frequency to limit the displacement that has a 2nd order attenuation with rising frequency. The acceleration transfer function can be defined by the classic 2nd order equation...
The best light intensity depends on the background light intensity as the eye pupils adjust to the field of view.
So there is no fixed optimum intensity is just enough to minimize eye strain from being too dark or too bright.
My estimate is that the contrast ratio or SNR of reflectance for...
