PWM DC Motor Speed Controller, 10-50V 40A Reversible Switch

Precision Digital Readout: 3-digit LED display provides real-time feedback on duty cycle, allowing for accurate speed adjustments without guesswork in tachometer-limited setups.<br>Full-Range Speed Control: Built-in potentiometer adjusts motor output from 0% to 100%; combined with the forward and reverse changeover, it suits bidirectional conveyor or tool tasks.<br>High-Current Handling: Supports 60A and 40A continuous current within a 10-55V DC input, reliably driving heavy-duty brush motors without overheating the internal MOSFET.<br>15kHz Quiet Operation: The 15kHz control frequency reduces audible motor whine, making it less intrusive during long machining, milling, or bench-top tool sessions.<br>Rugged Metal Shell: Solid metal housing acts as a heat sink and the circuit board from impact, dust, and stray workshop debris, prolonging in harsh environments.
