Description
The Rhino MD20Amp Motor Driver is a compact, high-efficiency single-channel DC motor controller ideal for high-torque applications. With an input voltage range of 6V to 30V, it supports motors requiring up to 20A continuous current, and burst current up to 30A for short durations.
This driver uses MOSFET-based H-Bridge circuitry for efficient bidirectional control, speed modulation via PWM (Pulse Width Modulation), and includes overcurrent and thermal protection mechanisms. Its rugged design ensures safe and stable performance even in demanding robotics and industrial automation environments.
