DollaTek PWM Signal Generator PWM Motor Speed Controller Light Control LCD PWM Pulse Rate Duty Ratio Adjustable Module PWM & PULSE Dual Mode Motor Drive Controller

• The signal generator is a device that provides electrical signals with different frequencies, rectangular waves, pulses and output levels and can directly control LED/motor/solenoid valves. It can also be used as a test signal source or stimulation source.
• PWM mode: adjust the frequency and the duty ratio. PULSE pulse mode: set the positive and negative pulse time, the number of pulses and the delay time.
• Features: LCD HD display. 1 channel signal output. High precision detection Support activated/disabled output. With start-stop button.
• Parameter memory function: the PWM motor speed controller can automatically save the set parameters to avoid data loss after a power failure.
• Voltage Input:3.3-30V, Connector Cable: 5.08mm Our motor regulator supports reverse polarity protection.

Features: Direct drive LED / motor / solenoid valve. PWM mode: support frequency adjustment and touch level adjustment.
