DC Motor Speed Regulator 5V-30V 12A

This DC motor speed regulator accepts input voltages from 5V to 30V DC and supports continuous currents up to 12A (360W). Its ABS housing measures 98 × 58 × 32 mm and houses a dual-MOSFET circuit with low internal resistance transistors and a high-speed driver stage — delivering stable, high-efficiency PWM regulation even at elevated duty cycles. Speed adjustment is performed using a digital encoder knob, offering superior accuracy, repeatability and longevity versus traditional potentiometers. Key configurable parameters include minimum and maximum output levels (preventing motor stall or LED saturation), PWM working frequency, and step resolution (adjustable from 0.1 to 25 per encoder click). Start and stop transition times can be individually set from 0.0 to 9.9 seconds — enabling gentle motor engagement and controlled shutdown. A front-panel push button provides immediate local control, while an external switch input supports remote or automated activation. Designed for practical deployment, it fits the industry-standard 5135 instrument case with detachable back cover — ideal for panel-mount installations in workshops, laboratories or OEM equipment. Package includes only the controller unit; no cables, adapters or accessories are supplied.
