SkyRC - Watt Meter ("SK-500005")
Features :
Measures energy (Wh), charge (Ah), power (W), current (A) and voltage (V)
Measures peak Amps, peak Watts ,voltage minimum (sag), peak temperature.
Measures temperature in both Celsius & Fahrenheit (optional temperature probe is necessary)
Auxiliary battery to power watt meter for measurement down to 0V
Accurate & precise – 0.01 A current and 0.01V voltage resolutions
Rugged – handles 50 A continuous and 100 A peak at 60V
Small & light with a tough plastic case
Precision Alu-Chrom current sensing resistor, with only 0.001 Ohms resistance
Factory calibration stores constants in EEPROM to compensate for component tolerances
We use it to :
Current through an ESC and motor
The temperature & peak temperatures of ESC, motor
Estimate battery's running time for car or airplane
ESC, BEC and motor efficiencies
Charge put into and discharge from a battery
Presence of peak currents that can damage components
Presence of voltage sags that cause components to operate out of specification
Why power is lost during acrobatics or extreme conditions
Effect of gearing and propeller size and shape on power consumption and battery currents Clever hobbyists will discover new applications to further improve electric model performance.
