Table 7-2

Voltage drop indicates as V = 100 X R X I X l

Rmeans resistance ( 52 /lo0 m) on the above table. I means electric current throughthe wire (A).

4! means the length of the wire (m).

The lengthof wire indicates round length, it means twice the lengthfrom generator to electrical tools.

7-2 DC OUTPUT

NOTE :Do not use DC and AC output simultaneously.

Due to a characteristic of the condenser voltage regulation, simultaneous use of DC and AC output creates voltage dropin DG output resulting in incapabilityforcharging batteries.

When the generator is employed to charge batteries, attentions should be paid to the specific gravity of electrolyte in the battery.

7-2-1 SPECIFIC GRAVITY OF BATTERYELECTROLYTE

The specific gravityof electrolyte variesby temperature ;so it must be converted to the one at20°C.

S20 = St + 0.0007 (t-20)

where

S20 :The specificgravity at 20°C

St :Measuredvalue

t : Temperature at the time of measurement(Electrolyte)
