More Information

Introducing our new state-of-the-art speed controller, designed to provide unparalleled speed stability for a variety of applications. With a speed stability better than 0.25%, this controller ensures precise and reliable speed control in a wide range of operating conditions.

With a speed range of 1KHz to 7.5KHz, this controller offers versatility, allowing it to be used in various speed control applications. It also features a thermal stability of 1% maximum, ensuring optimal performance even in temperature variations.

One of the standout features of this speed controller is its DROOP adjustability. The minimum position of DROOP adjust is 15Hz per 6Hz change in load current, while the maximum position is 400Hz per 75Hz change in load current. This allows for easy and precise adjustments to meet specific speed control requirements.

This speed controller also offers external speed adjustment capability, with a range of 200Hz (external 1K|?), further enhancing its versatility and control options. Additionally, the AUX input sensitivity is 148Hz per 1V, with a 10Hz impedance rating of 1M|?. This makes it compatible with various inputs and ensures seamless integration into different systems.

For fine-tuning and customization, this speed controller features an IDLE adjustment of 160 per 20Hz, allowing for adjustments from 95% of the rated speed. This ensures optimal performance and adaptability for different operating conditions and speed requirements.

In terms of power specifications, this speed controller operates on a supply voltage of 12V and 24V DC battery systems, with a ground negative polarity. It consumes a low power of 50mA and can handle a maximum output current of 10A at 10V. The minimum continuous current implementation is 2.5A to cater to a wide range of applications.

To ensure durability and reliability, this speed controller is designed to withstand harsh environments. It operates in a temperature range of -40 to 85 degrees Celsius and can handle operating humidity of up to 95%. It can also withstand shock of 20-100HZ at 500mm/Sec, making it suitable for rugged applications.

In conclusion, our new speed controller offers unmatched speed stability, precise control, and versatility for a wide range of applications. Its advanced features, such as DROOP adjustability, external speed adjustment capability, and IDLE adjustment, make it a highly adaptable and customizable solution.
