Brushless DC motor speed controller
12 - 48 VDC, max. 20 A | BL100-RO
Lin Engineering
• Peak current up to 20 Amps Peak
• Continuous current up to 10 Amps
• Maximum wattage of 500 Watts
(more than 500 Watts requires a larger heat sink)
• Chopping frequency of 20kHz
• Three fault outputs via LED (flashes on and off)
-- Wrong connection of hall sensors by the user
-- Short or over-current
-- Motor is connected but no rotation
• Closed-loop with hall sensors for speed control
• Direction of rotation change via hi/lo input change
• Direction mode which allows potentiometer to be used to rotate motor
forwards and reverse
• Brake input, which will stop motor rotation suddenly using hi/lo input
• Speed control via 0-5VDC or 0-10VDC with external voltage input
-- Option of using on-board pot for evaluation purposes
-- User can input their own voltage using the boards 2-pins (Power and Ground)
-- A simple jumper on the board changes from on-board pot usage to user's
input
