Subaru Robin Power Products RGV12100 Appliances without any indication as to power consumption

NOTE 2 : Motor-driven appliances mentioned in lets (3) and (4) vary in their required motor starting power depending on the kind of motor and start-up load. If it is difficult to determine the optimum generator capacity, select a generator with a larger capacity.

(5)Appliances without any indication as to power consumption

Some appliances have no indication as to power consumption; but instead the work load (output) is indicated. In such a case, power consumption is to be worked out according to the numerical formula mentioned below.

(Output of electrical appliance) ＝ (Power consumption) (Efficiency)

Efficiencies of some electrical appliances are as follows: Single-phase motor ・・・・・・・・・0.6 to 0.75

Three-phase motor・・・・・・・・・・0.65 to 0.9

Fluorescent lamp ・・・・・・・・・・・0.7 to 0.8

The smaller the motor, the lower the efficiency.

Example 1 : A 40 W fluorescent lamp means that its luminous output is 40W. Its efficiency is

0.7and accordingly, power consumption will be 40÷0.7=57W. As explained in Item(2), multiply this power consumption value of 57 W by 1.2 to 2 and you will get the figure of the necessary capacity of a generator. In other words, a genera- tor with a rated output of 1000 W capacity can light nine to fourteen 40W fluores- cent lamps.

Example 2 : Generally speaking, a 400 W motor means that its work load is 400 W. Efficiency of this motor is 0.7 and power consumption will be 400÷0.7=570 W. When this motor is used for a motor-driven tool, the capacity of the generator should be multiple of 570W by 1.2 to 3 as explained in the Item (3).

570 (W)×1.2 to 3=684 (W) to1710 (W)
