Utility measurement

The main characteristics of a microwave in an environment of ordinary consumers are considered performance and volume. The dimensions of the appliance are determined in liters (13–42 l), and the power in watts (W). The numerical values ​​of the power parameters increase in proportion to the volume / liter of the apparatus. For a family of 4 people, a microwave with a volume of 20–28 l and a power of 1.5 kW is enough. But how to check the necessary parameters of a kitchen appliance for the needs of an average family?

The breadth of its functionality and targeted use in the kitchen depend on the design of the device:

  • 500-800 W - for defrosting, heating and cooking simple dishes;
  • from 900 W - cooking complex dishes using additional functions.

Low network parameters when several household appliances are turned on at the same time can reduce the power of the microwave oven.


It is necessary to make sure that the home / office power supply is reliable so that the load from working at full capacity of the microwave oven does not lead to fire hazardous overloads.

Appetites of modes

Tools combined in a home microwave:

  • 500–1700 W - magnetron, microwave heater;
  • 1.5 kW - grill (quartz / heating element);
  • 2 kW - a convector forcing hot air with a fan.

A quartz-type grill is more economical, since it consumes less energy than a heating element, which also takes up the useful volume of the camera. Adding grill and convection functions (what it is?) automatically increases the total energy consumption and power demand. Separate use of additional microwave tools is provided, which automatically reduces energy consumption.

Discrete and invertor principles

The amount of microwave energy supplied depends on the magnetron, a heater for intense radiation of radio waves. The principle of operation of a discrete device is based on the supply of a constant 100% of a given power. When switching to lower values ​​of power parameters required in various modes of the device, the emitter alternates on / off cycles for the time set by the timer. The duration of the periods depends on the selected mode - the longer the on, the more heating.

More advanced inverter technology of the microwave device involves a gradual increase in heating power. This principle of operation of the appliance optimally preserves the nutrients and texture of the products. There are electrical appliances equipped with two microwave emitters for even distribution of energy. In everyday life, the microwave power consumption varies from 500 to 1700 W - the speed of the processes in the device chamber depends on this value. In the industrial sector, the maximum power of the microwave oven is determined at 2500 watts.

It’s also useful to know about the basic microwave operating principles.

Where is the data indicated

In the accompanying documents of household appliances, the parameters of the microwave produced by the magnetron (heater) forces are not indicated - only the amount of electricity consumed by the microwave oven devices in totality. The output power emitted by the magnetron is proportional to the supply voltage.

And how do you know what power a kitchen appliance is? The specifications declared by the manufacturer are indicated:

  • on the back of the device in the plate with technical data;
  • in the attached user manual, instructions.


Depending on the purpose and the specific recipe, the microwave oven is used in modes referred to in various versions. The definitions of microwave heating levels are applied:

  • 10%, 100 watts - low, low. The mode of automatic heating of the dish at the end of cooking, defrosting / heating of delicate food.
  • 25%, 200-400 W - medium / low, below average. Thawing / heating of semi-finished products and raw foods; cooking dishes that do not tolerate significant temperatures.
  • 50%, 500 W - medium, medium. Slow cooking soups, fish / meat dishes; quick warming up of cooked food.
  • 70%, 700 W - medium / high, above average. Cooking fruits / vegetables, sauces / drinks, poultry and simple dishes.
  • 100%, 800–1000 W - high, maximum. Intensive cooking, rarely used.

The most popular among users is the average power of electronic devices. All values ​​are programmed by the manufacturer or set manually. Most modern models provide the function of remembering the modes used.

Types of control units

Depending on the type of the selected administrative panel, the power control of the device depends. Management systems are divided:

  • mechanical - rotary controllers of time, power, grill mode;
  • push-button - tactile board and display;
  • touch buttons.
Manual power adjustment

The mechanical type is suitable for elderly family members who are better off setting microwave modes in a familiar and understandable way. The button control unit is equipped with a timer, convenient for accurate observance of the conditions of the recipe. On-screen digital / text displays of such furnaces display prompts. Touch modification allows you to accurately program modes taking into account power.
