Save Costs With Peak-Rated Power Supplies

Notice in this table that in some instances we require different parameters for the peak power (Wp), peak duty cycle, and peak period (t = 5 s or less). In those cases, our non-peak power (a) changes accordingly. As long as we remain within the specified constraints, we can accommodate many different peak versus nonpeak power and duty-cycle scenarios to fit different applications. The blue numbers in this table relate to parameters from the example described above.

COST SAVINGS & OTHER BENEFITS
Via the previous examples, we demonstrate that by using a 600-W power supply with a high peak-power rating, we can support a short-duration peak load of up to 2000 W, over three times normal. Obviously, the cost of the 600-W supply is significantly lower than employing an 1800- or 2000-W continuous-rated supply.

In OEM lots, the cost savings for using peak-rated supplies can amount to 75% or more. Additional benefits are possible since the 600-W supply is significantly smaller and lighter than a 1800-W supply: 83 in.3 versus 177 in.3 and 3.52 lb versus 8.36 lb, respectively. Also, the 600-W supply is environmentally friendlier.
