HW-687 PWM speed controller - 5-35 V, 5 A, 90 W
This goes with it
Description
Product Overview
- Speed controller for DC motors and LED lamps, PWM-controlled operation
- Voltage range 5 V to 35 V, maximum current 5 A
- Control via PWM signal from a microcontroller or potentiometer
- DIN rail mounting possible, compact design
- Thermal regulation through cooling, thermal shutdown at approximately 80 °C
Product Description
The speed controller operates according to the PWM principle (pulse-width modulation) and controls DC motors or LED lamps within a voltage range of 5 V to 35 V. With a maximum current of 5 A, the module is suitable for medium-duty applications in prototyping and for controlling small motors.
Control is provided via PWM input signals, for example from microcontroller boards or analog potentiometers. The module converts the control signals into a variable voltage, continuously adjusting the motor speed or the brightness of LED lights. An integrated freewheeling diode protects against reverse voltages when operating inductive loads such as coil motors.
Applications include variable lighting in development projects, speed-controlled operation of fans, or controlling model motors via PWM commands. The controller can be easily integrated into electronics learning kits where motor control is to be demonstrated.
The module features thermal regulation and shuts down thermally when the temperature exceeds approximately 80 °C to prevent damage. On the input side, it processes a PWM signal at standard logic level, enabling connection to common development boards. The motor's power supply is independent of the control signal.
Safety Notice
The module is intended exclusively for building prototypes and for testing and development purposes and must not be installed in the household power circuit. Current consumption above 5 A or voltages exceeding the specifications pose a risk of fire and damage. Work on or near electrical installations must be carried out by a qualified electrician; if there is any uncertainty regarding the power supply or motor connection, consult a qualified electrician before commissioning.
