Product Usage Instructions
Connections/Wiring:
The SmartElex 30S can be connected to a 7V-28V battery or power supply. Follow these steps:
- Connect the power input to the terminals labeled B+ and B-.
- Ensure the input voltage is within the specified range of 7V to 28V.
- Use appropriate wire gauges for power connections to prevent overheating.
- Connect motor terminals to the motor terminal of the driver.
FAQ
- Q: What should I do if the Error LED is glowing?
- A: The Error LED indicates Under Voltage Lockout, ensure the input voltage is above 7V.
- Q: How can I prevent overheating of wires?
- A: Use appropriate wire gauges for power connections and avoid using undersized wires.
Introduction
SmartElex 30s is a dual-channel motor driver capable of supplying 30 amps continuous with peak currents up to 85 amps (2Sec) per channel. It can be operated from PWM
Features

Connections/Wiring
SmartElex 30S can be used with power supplies or batteries. Input power is connected to the power terminals labeled B+ and B-. The input voltage range is 7V to 28V. The input current is dependent on the motors being used and the load placed upon them. As a general rule of thumb, you should use the thickest wire that is practical to make power connections, especially on the battery leads. Using undersized wire will lead to the wire getting hot, and can lead to elevated temperatures on the SmartElex 30S as well. The main power connections to the SmartElex 30S are on the rear edge of the board. Connections are made to large black screw terminals. These terminals will accept 10 to 28 gauge wire. Using stranded wire it is possible to run twinned 10 gauge wire connections to the battery terminals. This is often a good idea if your design will be running both motors near or above the 30 amp continuous limit. For the motor connections, single 12 gauge wires should be sufficient for all applications.
