KT36/48SVPRCLDB 36–48V 30A Sinus Controller – Black
KT36/48SVPRCLDB 36–48V 30A Sinus Controller – Black
The KT36/48SVPRCLDB is a modern, high-performance sine wave controller designed for electric bicycles equipped with 36V or 48V electrical systems. Thanks to advanced sine wave control technology, it delivers exceptionally smooth, quiet, and comfortable motor operation, enhancing the riding experience for both everyday commuting and more demanding routes.
Compared to traditional square wave controllers, a sine wave controller offers several key advantages:
- Significantly reduces motor noise
- Provides smoother starts and acceleration
- Improves the overall performance and refinement of the drive system
- Increases energy efficiency
- Reduces wear on electrical and mechanical components
The controller supports both 36V and 48V systems and delivers a maximum operating current of 30A, ensuring excellent acceleration and stable performance even under higher loads.
The KT36/48SVPRCLDB features a durable black aluminum housing that effectively protects the internal electronics from harsh operating conditions. It is designed for long-term reliability, durability, and seamless integration with electric bike systems based on KT components.
This controller is an excellent choice for riders looking for a high-quality motor controller that provides smooth motor operation, improved energy efficiency, and a superior riding experience.

Reverse GearNotes
When connected to a KT-LCD3 display, the controller can be configured to match a specific e-bike system. The display allows you to enable pedal assist, set the 25 km/h speed limit, adjust the current limit, and configure many other parameters. The display is optional—the controller also operates without it, although only its basic functionality is available.
With sine wave (and vector) controllers, the motor's maximum speed is typically around 8% lower than its rated specification. In return, the motor delivers approximately 8% higher torque, resulting in stronger acceleration and improved climbing performance.
Do NOT use with BIONX motors. These motors are not compatible with KT controllers and may suffer serious damage if connected.
If you plan to operate the controller close to its maximum power output, ensure it has adequate cooling. For example, do not install it in a completely enclosed space without airflow. The controller can be mounted outside an enclosure, but it should always be installed with the cables facing downward to prevent water from entering the housing along the wires.
The controller supports motor temperature monitoring. To use this feature, the motor must be equipped with an NTC 10k temperature sensor.
