PWM speed controller / motor controller 5 A, 12 – 24 V
Features:
This speed controller is designed specifically for low voltage electric motors. The main applications are: Variable speed control of DC Drills, model cars, windshield wiper motors and other power tools. Due to the pulse width control, which is about 20 kHz, with a frequency, the power loss is low even at low speeds. By using a MOSFET transistor, the output current from 0 to 5A can be continuously adjusted with a potentiometer, the electronics are protected in case of sudden blocking of the motor. The setting of the motor extends from a complete standstill to full speed. With another additional potentiometer to set the device offers a way load-independent speed stabilization.So that the torque and speed losses are avoided at higher loads, and reaches a steady engine operation, even at low speeds.
Highlights:
1.High frequency (about 20kHz), noise-free operation.
2 high efficiency by using Power MOSFET.
3 current limit adjustable.
4 Adjustable “I x R” – compensation (load compensation).
5 Electronic short-circuit and overload protection.
6 panel mounting.
7 Compact size.
