The ZDBLS1-2 is a simple sensorless brushless DC motor controller. Operation is between 5V and 14V and the controller will simply run the motor once powered up at a speed proportional to the input voltage. This is intended for simple pump or motor applications and enables users to quickly operate a sensorless motor without external signal inputs. The unit requires no programming and will simply drive appropriately matched motors once power is applied. The controller can operate up to 1.5A.
