The ToolkitRC WM150 Watt meter allows testing of motors and other DC devices. The most common usage is to control a brushless ESC and measure the resulting power usage of motors. Up to 150W can be measured via the unit. The voltage and current data is graphed and can be visible on the built in colour screen.

Features:

- Output PWM signal with an accuracy of 1 microsecond.
- Low voltage alarm. When the voltage is lower than 6V and USB power is not supplied, it will alarm.
- Real-time detection of voltage, current, power - displayed graphically
- Firmware upgradeable
