Product Description
"This speed controller was developed especially for low voltage electric motors.
The main fields of application are: Infinitely variable speed control of direct current drilling machines, model cars, windscreen wiper motors and for power tools.
Due to the pulse width control, which works with a frequency of approx.
20 kHz, the power loss remains low even at low speeds.
By using a MOSFET transistor, the output current can be continuously adjusted from 0 to 5A with a potentiometer, whereby the electronics are protected in the event of a sudden blocking of the motor.
The adjustment range of the motor extends from complete standstill to maximum speed.
With another additional potentiometer, the device offers a possibility to set load-independent speed stabilization.
This avoids torque and speed losses at higher loads and ensures smooth motor running even at low speeds.
high clock frequency (approx.
20kHz), thus low-noise operation.
