input power vs power consumption

input power vs power consumption

Furthermore, if the same microwave oven is only on for a minute its consumption would be 0.023 kWh (i.e 1.4 kWh / 60 minutes). Similarly, when keeping food warm, you can set the microwave to just 10% consumption or Power Level 1. Power rating is specified using the unit Watts (W) or Kilowatts (kW). Podcast 282: Stack Overflow’s CEO reflects on his first year, MOSFET power dissipation calculations - Diodes Inc. datasheets, Embedded System power requirement calculation, heat dissipation in watts of equipment in a box. Let us take an 1100 watt microwave oven that has an Input Wattage of 1700 Watts. What RBF policy will be default on SegWit v1 nodes? Input Power is the power, which is required by the appliance at its input i.e., from the plug point. As you may know, almost all microwave ovens have standby mode when plugged. How can I estimate the power dissipation if the only power listed is the power consumption? I'm currently running some power dissipation analysis or thermal calculation on a system and the way I do it is by looking at each part's data sheet and see if they list its power dissipation. The output power of the device is transferred elsewhere in some useful form. Flight Levels shall be transmitted by pronouncing each digit separately. Hence, it is important that you know the power of your microwave as well as the PRECISE cooking time for various type of foods in your microwave. There is no way to guess efficiency without actual measurements or asking the supplier. In a good design, are expecting to use 80% of the current from the source or what is the threshold? A typical microwave oven has an efficiency of 65%. All microwave ovens consume energy in standby mode. I use AM100S/5-A and specs: Output Power (max) of 100W, output current is 20A, output voltage is 5 volts, and its efficient is 75%. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Should I tell a colleague that he's serving as an editor for a predatory journal? It is the Input Power. Densely packed food or large portions of food are hard for microwaves to heat up. average electricity rate in United States. The Overflow #45: What we call CI/CD is actually only CI. Basically, if this rated power is not supplied, then the microwave oven may malfunction. Power at the load is the output power, which can be delivered by the appliance.

The mentioned microwave would have an energy consumption of 1.7 kWh IF it operated continuously for an hour at full 100% Power Level. Asking for help, clarification, or responding to other answers. On the other hand, a 1200 Watt microwave would consume 1.85 kWh of energy if it operated continuously for an hour. P in is the input power consumption in watts (W). Here it would not only defrost your food, but also consume mere 40% of the max power consumption. Power dissipated probably refers to the losses associated with the device that are usually dissipated as heat. This is especially true if you have low powered modeleval(ez_write_tag([[336,280],'kitchengearoid_com-large-mobile-banner-2','ezslot_8',113,'0','0'])); Hence, instead of increasing the time cycle for reheating the large meal, it is rather advisable to stir it from time to time. A power Supply transforms input to output with idle losses and dynamic losses dependent on load. You may be familiar with the common output powers for microwave ovens that range from 700W to 1250W for typical home use. However, the same microwave would half its consumption for the same cooking cycle IF its power level is set to 50%.eval(ez_write_tag([[728,90],'kitchengearoid_com-large-leaderboard-2','ezslot_1',111,'0','0'])); Most microwave ovens have a total of 10 power level settings ranging from 1-10 with each setting representing a 10% increment or decrement. If it transmits energy to other equipment, 85% is a reasonable efficiency. You might expect 80% at max load as typical. In turn, this would cost you half as much for the same time span.eval(ez_write_tag([[250,250],'kitchengearoid_com-leader-2','ezslot_11',129,'0','0'])); Hence at 50% power level a microwave oven with 1700 W input power would consume 0.85 kWh (1.7 kWh x 0.5) if operated continuously for an hour. Also, is there any way you can correlate the power dissipation of the load to figure out the power dissipation in the power supply that feeds it?

This tip is for the most energy savvy consumers. If the load has 15 watts of losses and its efficiency is 85% than it's input is 100 W and the power supply is fully loaded. The efficiency is zero only for the heater, but not computer, right? This translates to 0.186 cents per minute. The input power listed in the data sheet is usually the maximum value that may not occur under normal operating conditions. It only takes a minute to sign up. All I know for the load the power supply connects to is that it(the load) dissipates 15Watts. For other equipment, input power or "consumption" is essentially the same as dissipation. or 5W at 30W out. If a microwave oven has a rated power of 1400 Watts (1.4 kW), then its consumption would be about 1.4 kWh IF it were continuously on for an hour. A power Supply transforms input to output with idle losses and dynamic losses dependent on load. In other words it would cost you about 22.42 cents to operate it continuously for an hour (1.7 kWh x 13.19 Cents) at the full 100% Power Level setting. It does not have any energy output except for the possibility that it transmits data someplace else, but that would be a very small amount of energy. I used the worst case scenario because I don’t know how much current is drawn by the load. So what is the power consumption of a microwave oven? At an average, the power consumption of a microwave oven is about 1.4 kWh. eval(ez_write_tag([[250,250],'kitchengearoid_com-leader-1','ezslot_7',112,'0','0']));Take water for instance. I know that this load will not draw the max current from the power supply, but if I had to guess to avoid using the worst case scenario what would you say the this load would draw? New tubeless setup: losing air through spoke holes. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. It's a computer in this case.

How do I calculate power dissipation on this supply? Is the power consumption the power at the input of the electrical part? Taking a typical efficiency of 65% we get following Input Power for the corresponding Output Power as well as the corresponding consumption. The energy consumption takes both the rated power as well as the cooking time into consideration. Also recall from earlier that all microwave ovens have Power Level settings whereby you can select the percentage of the total output power for your cooking. Different food or tasks require different Power Level selection. The following are the typical OUTPUT wattage ratings for home microwaves. Thanks for contributing an answer to Electrical Engineering Stack Exchange! Power efficiency. Alternatively, if you used the same oven for 1 minute at 100% power level, then you would be billed about about 0.37 cents (1.7 kWh / 60 minutes X 13.19 Cents). It may be difficult to calculate loss dissipation from data sheet information. Copyright © 2020. At KitchenGearoid, instead of looking at the appliance specifications with a birds eye view, we aim to provide a microscopic view with the goal to detail each and every aspect. Created by You would have to consider that the efficiency of a computer is zero or almost zero.

What do you think? Depending on the purpose of loss dissipation, you may want to consider either typical actual operating conditions or worst case conditions. The power supply losses are 33.3 W at full load. You are billed based on the energy consumption and NOT on the rated power. In your example, the power adapter is rated to use a maximum of 58 W (0.24*240), but can output only 5*1.5=7.5 W. So, worse case based on the label, it will use 58 W, but only supply 7.5 W to your device, so about 13% efficient. Electric motor has input power consumption of 50 watts.
