Description
The Cytron 25A 7V-58V DC Motor Driver (MD25HV POT) is a robust, high-voltage, single-channel bidirectional motor driver engineered for demanding motion control tasks. Designed to handle DC motors ranging from 7V to 58V, this driver features a high-efficiency discrete NMOS H-Bridge architecture capable of sustaining 25A of continuous current without requiring bulky external heat sinks. It is an ideal solution for high-performance applications, including industrial automation, electric vehicles, and heavy-duty robotic platforms.
The MD25HV POT offers unparalleled versatility in control methods: it can be driven via PWM/DIR signals from microcontrollers like Arduino, Raspberry Pi, or industrial PLCs (with a wide logic voltage compatibility of 1.8V to 30V), or controlled directly using the included potentiometer and switch for standalone operation. The integrated 5V buck regulator simplifies system design by powering your host controller directly from the high-voltage motor supply. With advanced safety features, including active current limiting, thermal protection, and undervoltage shutdown, this driver ensures reliable operation even under stressful load conditions.
Note: Product images are for reference only. This unit does not have reverse-voltage protection. Please verify polarity during battery connection to prevent instantaneous damage to the driver circuitry.
