KT 15A Square Wave
Budget KT square wave controller for 250-500W e-bike conversions. 6-FET design with auto-detect 36V/48V. Square wave (trapezoidal) commutation — cheaper than sine wave but with audible motor whine and choppier low-speed operation. Best for geared hub motors where gear noise already dominates. Programmable via KT-series displays.
In brief: 24–48V controller. 7A continuous. 15A peak. Square Wave, dual mode support. From $51.
