6-2 DC OUTitJT
When the generator is employed to recharge batteries, attentions should be paid to the specific
gravity of electrolyte in each battery.
6-2-l MEASUREMENT OF ELECTROLYTE’S SPECIFIC GRAVITY
The specific gravity of an electrolyte varies according to temperature; so it is converted to one
in case of 200C.
s20 = St + 0.0007 (t - 20)
where
S20: The specific gravity at 200C
St :
Measured value
t : Temperature at the time of measurement (Electrolyte)

6-2-3 BATTERY CAPACITY
The battery capacity is expressed in the unit of AH (amperehour). One AH stands for the
capacity capable of one ampere current for one hour.
6-3 SIMULTANEOUS USE OF AC/DC OUTPUT
With a generating engine of rated 1000 W output, AC and DC are simultaneously available but, in
this case, be careful not to exceed the total power consumption.
50 Hz
below 700 W
60 Hz
below 900 W
Note:
Max. DC output is 100 W (12V x 8.3A).
