Enhance your electric bike's performance with this high-quality 40A Sine Wave Electric Cycle Controller, designed for compatibility with a wide range of brushless motors. Supporting 36V, 48V, and 52V systems with power ratings from 1500W to 2000W, this controller ensures smooth and efficient motor control whether your motor has hall sensors or not. Equipped with advanced features and durable materials, it is an ideal choice for reliable and stable electric bike operation. Key Features: · **Wide Compatibility:** Compatible with 36V1500W, 36V2000W, 48V1500W, 48V2000W, 52V1500W, and 52V2000W brushless motors, both with and without hall sensors, offering versatile use for various electric bike setups. · **Self-Learning Function:** Automatically detects motor parameters for optimal performance and prevents motor reversal by using the learning line feature, simplifying installation and enhancing safety. · **Efficient Heat Dissipation:** The controller’s outer casing features a groove design made from aluminum alloy and ABS materials, providing excellent heat dissipation to protect internal circuits and prevent thermal overload during extended use. · **Safe XT60 Plug:** Includes an XT60 plug with an insulating plastic case designed to resist burning and enhance battery safety during operation. · **Three Operating Modes:** Offers flexible control with a 3-mode setting and learning line that prevents motor reversal; if reversal occurs, simply reconnect the learning lines for forward rotation without continuous connection. · **Speed Limit Line:** Integrated sine wave technology reduces noise and ensures smooth, stable riding. The speed limit line allows easy speed limit adjustment—disconnecting the two speed limit wires disables the speed limit function for unrestricted performance.
