Output Device¶
This week, our group - Darren, Terry, and me (Jason) try to measure the power consumption of an output device.
Group assignment

The machine we use for testing¶
This week, we used the Wantek DC Power Supply nps306w Buy here it’s built-in voltage, current and power meter to measure the power consumption of the servo motor or LED ring.
Servo motor and LED ring consumption measurement¶
This is the electrical specification for TowerPro MG90s server motor.
▼ You can see that the horse is stopped, switched, blocked and also affects the required current.
Now let’s measure the actual current and power!
TowerPro MG90s Servo motor
| Status | Volt | Current | Power |
|---|---|---|---|
| Idle | 4.9V | 0.00A | 0.00W |
| Normal Rotate | 4.9V | ~0.13A | ~0.18W |
| Full load | 4.9V | ~0.68A | ~3.33W |

| Volt | Current | Power |
|---|---|---|
| 4.9V | 0.03A to 0.04A | 0.14W to 0.19W |
