Brushless speed controller

The BL100 brushless dc speed controller has an input operating voltage up to 48 Vdc and 10 A of continuous current, 20-A peak. Closed-loop control with adjustable P and I values lets users fine-tune the controller.

The BL100 can be used in either analog or digital mode: Analog mode lets users adjust speed and direction via the onboard potentiometer and external potentiometer for higher resolution. Digital mode allows for communication via RS-485 (RS-232 and USB converter cards are available) and comes with a complimentary graphical-user interface that lets users configure acceleration and deceleration profiles along with controlling multiple speed controllers through assigned character addresses.
