Watt-Meter MX 8120     #92549
    
       
This measuring device is the ideal “assistant” for any electric
fl ight enthusiast, helping to optimise the combination of propeller,
motor and battery.
The MX 8120 also provides valuable information for battery
maintenance.
The screen constantly displays the actual values for voltage
[V], current [A] and power [W]. The unit also calculates and
displays the charge quantity [mAh] “moved” (i.e. charged-in or
discharged).

A separate battery is not required, as the MX 8120 draws the energy
it needs to operate from the energy source connected to it.
Typical applications for the MX 8120 are as follows:

• For testing electric power systems: Measuring the actual values
of current, voltage and power, and the quantity of charge drawn
from the fl ight or drive battery (connect the unit between the
battery and the speed controller)

• For charging batteries: recording and displaying the quantity
of charge and the actual values for current, voltage and power
(charge power) (connect the unit between the battery and the
charger).
