Subaru Robin Power Products R1200 Portable Generator User Manual


 
calculate the power consumption of the device involved.
The calculated power consumption is
adjusted depending on the type of the load, and according to paragraphs from (1) to (3).
(Power consumption) = (Mechanical equivalent of a device) + (Efficiency)
Efficiency
Motors: 0.6 2. 0.8
Fluorescent lamps: 0.7 x0.8
Example: As for a 40 W fluorescent lamp with a lighting output of 40 W, and assuming that the
power consumption of this lamp is 0.7, the power consumption can be calculated as
follows:
40 + 0.7 = 57 W
Furthermore, as per paragraph (2), the power consumption is multiplied by a factor of
1.2 to 2, producing a power consumption of 70 to 115 W. Therefore, with a generator
having a rated output of 1000 W, 8 to 14 lamps can be used.
Example: In the case of a 200 W motor, the mechanical equivalent of the motor is 200 W.
Assuming that the efficiency of the motor is 0.7, the power consumption is calculated
as 200 I 0.7 = 285 W. Similar to the above, the calculated power consumption is then
multiplied as per (3)a, or (3)-a, taking into account the type of the motor used and
the starting condition. The table below shows the range of loads applicable to the
generator with 1000 W rated output.

Note 1: With motor-driven tools specified in paragraphs (3) and (4), the generator of the
said capacities are required only when starting the motors for the respective
appliance.
Once the motor has started, power necessary for normal running is
only 1.2 to 2 times larger than the rated power, and the surplus capacity of the
generator may be used for other electric appliances.
Note 2: As for the tools using the motors specified in paragraphs (3) and (4), the power
requirement for starting the tools varies according to the types of motor and the
load conditions at the time of starting.
