SKYRC Watt Meter (WM010)




Price

S$38.00

Description

  • 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

Features

Application:

Watt Meter measures current, voltage, peak current (Amps), peak power (Watts), minimum voltage (Volts), power (Watts), energy (Watt-hours), charge (Amp-hours)  and temperature, peak temperature values for you, in real-time, for the circuit in which you connect it


Now you can stop wondering what's going on with your electric model and get answers that allow you to apply science to your hobby. The precise measurements you collect will help you fine tune your model to get all the performance that you paid for.


With watt meter function, it is now easy to determine things like: 

  • 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.

Functions:

There are two functions of this compact device:

1) Battery Checker - The LiPoPal can check the voltage of each cell of a lithium battery pack and remaining capacity in percentage %.

2) Self Voltage Balancer - This program can equalize the individual voltages to their lowest one. Balance operation automatically starts about 5 seconds after the battery pack is connected. When the voltage difference between cells over 0.02V, the balancer will start to work. The corresponding “V” will be blinking when it is balancing. When the voltage difference between cells reaches 0.01V or less, balance operation ends and the device enters the sleep mode and “SLP” will be displayed on the LCD.

(*1).0V minimum with auxiliary power.

(*2)50A continuous, 100A peak, assumes device’s wires are in free air and attached to connections at or below temperature of 35 flow.

100A operation time depends on ambient temperature and wiring temperature.

You can calibrate all values to zero by pressing “SW” button for more than 3 seconds.
