ToolKit RC WM150 Advanced Watt Meter

The Tool Kit RC WM150 1~50V 150A Advanced Watt Meter is a must-have for all users of electric powertrains for RC model airplanes. The full color wide angle backlit LCD display, supplies graphs and histograms showing current draw, voltage, and watts instantly and in real-time. The 32-bit ARM processor provides high-speed sampling and instant recording. This meter also acts as a USB flash drive so you can download your data to a computer or other device. A USB cable is provided in the box for data transfer and can be used to upgrade the firmware of the WM150.

The WM150 is very easy to use: Simply connect your motor to the ESC, then connect the ESC power and signal leads to the watt meter.  Then connect your battery supply. Once everything is connected the controller, the knob on the side of the unit controls the PWM output to the ESC to vary the speed of the motor from zero to full power. The WM150 has been designed for a wide input voltage of 1~50V and will handle current draws of up to a maximum of 150A. In addition, this device can act as a power supply and PWM generator, which makes it perfect for testing motors, and servos.

With the WM150 advanced watt meter, there’s no more guessing how much current your set-up is drawing or what power you are developing. You can test out different propellers and batteries to achieve optimum performance without overloading your gear.
