01TRANSFORMERS & REGULATORS
Precise control for variable DC motors
A compact module that sits between your power source and the motor, this regulator brings order to variable speed applications. Its clean interface replaces guesswork with clear digital feedback.
Designed for hobbyists and engineers, it manages current flow with precision. The unit suits projects requiring stable, adjustable performance without complex wiring or external microcontrollers.
02PERFORMANCE
Smooth starts without electrical shock
When the system powers up, the controller ramps the current gradually rather than delivering a sudden surge. This soft-start approach protects the motor windings from thermal stress during ignition. By managing the initial draw, the device extends the operational lifespan of connected machinery while maintaining consistent torque output.
FUNCTION
Adjustable frequency and duty cycle
The internal processor allows users to tune the working frequency between one and ninety-nine kilohertz. This range accommodates various motor types, from standard brushed units to specialized actuators. A rotary switch provides continuous variable control, enabling fine-grained adjustments to speed without discrete steps or abrupt changes in performance.
RELIABILITY
Memory retention and polarity protection
Should the power supply fail, the controller retains the last saved parameters, preventing the need for recalibration upon restart. Built-in reverse polarity protection guards against incorrect wiring connections, safeguarding the circuit board from damage. These features make the unit robust enough for experimental setups where conditions may vary.
AT A GLANCE
The key points
- Regulates DC voltage from 5 to 30 volts at 150 watts
- LED digital display shows duty cycle and frequency
- Soft-start feature prevents inrush current on startup
- Rotary switch allows continuous variable speed adjustment
- Stores set parameters automatically after power failure
Highlights
- [Power Parameters] Voltage
- 5-30V; Current: 5A; Power: 150W [Protection Function] When the motor starts, the current increases slowly without inrush current, which effectively protects the motor and extends the life of the motor
- Setting Method
- Normal display mode: ◎ Short press the potentiometer: Turn the output signal on/off
- Tips
- ◎ The duty cycle is displayed by default
