The Mini-KVD is an electric motor controller designed by Kelly Controller for small electric vehicles such as electric bikes, scooters, and tricycles. It is a compact and lightweight controller with a nominal voltage range of 12V to 48V and a one-minute peak current of 120A or 200A. The controller uses high-quality components and advanced software algorithms to provide smooth and efficient motor control. It features a waterproof design, making it suitable for use in various weather conditions. Additionally, the Mini-KVD comes with several safety features such as over-current protection, thermal protection, and short circuit protection. The controller also supports regenerative braking, allowing the vehicle to recover energy during braking. Overall, the Mini-KVD is an ideal controller for small electric vehicles that require high-performance and reliability.
