Feature: 1. Split digital display, forward rotation and reverse rotation, input voltage is DC10‑55V. 2. Speed adjustment adopts PWM technology, which has the characteristics of high conversion efficiency, wide speed adjustment range, and stable performance. 3. The aluminum shell is difficult to crash and can protect the product from accidental strikes. 4. The input current is required to be greater than the operating current of the motor, the output current is determined by the load. 5. Continuous current is within 60A, power conversion 3000W, speed regulation mode is on\off linear potentiometer 270 degrees.
