Controller KT48SVPRCKB 48V 45A sinus
KT48SVPRCKB 48V 45A Sine Wave Controller for Electric Bicycles
The efficient and modern KT48SVPRCKB controller is designed for electric bikes with a 48V system. Thanks to sinusoidal technology, it ensures exceptionally smooth and quiet motor operation, significantly improving riding comfort.
Compared to standard block (square wave) controllers, the sine wave model:
- reduces motor noise
- improves acceleration smoothness
- increases energy efficiency
- minimizes wear on drive components
The controller is equipped with high-quality, waterproof HIGO connectors, ensuring reliability and resistance to weather conditions. They allow for quick and safe connection of essential system components.
Additionally, the controller supports lighting connection, enabling convenient control of lights directly from the e-bike system. It also supports a Bluetooth (BT) module, allowing extended functionality through wireless communication (e.g., with a mobile app).

Comments
After connecting the controller to the KT-LCD3 or KT-LCD8s display, it can be programmed for a specific installation. It allows you to activate assistance, limit up to 25 km/h, limit current and much more. The display is optional, the controller also works without it, but then has basic functionality.
On sine (and vector) controllers, the motor develops a speed approximately 8% lower than indicated in the motor data, but in return it achieves 8% higher torque.
DO NOT use with BIONX motors and electric scooter motors. These engines are not compatible with KT controllers and may lead to a serious failure.
The controller MUST NOT operate mounted in a plastic box if the box does not have ventilation holes. Make at least 4-8 holes with a diameter of 15 mm in the walls of the box and a water drainage hole. The controller is splash-proof and any water getting into the box will not harm it.
The store guarantees repair or replacement of equipment for up to 24 months for consumers and 12 months for companies from the date of purchase. Complete the complaint form available on the store's website.
