WARNING!
Choosing load it is necessary to remember, that at
reduction of the input voltage increases input current,
respectively maximum-owned power output of the regulator.
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.
