The schedule of dependence of admissible output power vs. input voltage is shown in the Fig. 2. It is necessary to strictly adhere to this dependence.In determining the load stabilizer should take into account the total power consumption of all the consumers, connected to the stabiliser. Full power is the power consumption of electricity internally, it consists of active and reactive components. In the characteristics of instruments of active power is always stated in watts (W), full - in volt-amps (VA). Full power (VA) active power (W) connected by a factor of cos , which is also indicated in the characteristics of the consumers. For consumers, that convert electricity into heat and light (incandescent lamps, heaters, cookers, irons, etc.), reactive component of the no. Reactive component is among consumers, which includes electric or induction coil (vacuum cleaners, refrigerators, electric meat grinder, kitchen combines, an electric drill, elektrorubanki, polishers, pumps, etc.). In this case, for the calculation of the full capacity of the need to value rated power divided into cos. For example, if the nameplate capacity of the drill is 600 W, and the value of cos for her - 0,8, the full power drill will be 600/0, 8=750 W.Besides it is necessary to take into account that many of the devices, for example - refrigerators, at the moment of start consuming significantly more power than in normal mode. In such cases, the value of the inrush current must also be specified in the instructions to the unit. Therefore, in cases when the load is the electric motor, which is the main consumer of this device (for example, submersible pump, fridge), to avoid overloading the stabilizer at the moment of switching on the device, you must have a three-time power reserve.Proceeding from the above, it is recommended to load stabilizer with 20-25% of the stock from its maximum power: ensuring the "lenient" regime of work of the stabilizer can significantly increase its service life.ATTENTION!In determining the actual load on the regulator should take into account the influence of reactive component by power consumers and values starting currents.
