XY-KPWM signal generator, 1 channel, for generating electrical PWM (Pulse Modulation) signals at various frequencies, between 1Hz and 150kHz, offering square waves and adjustable output levels through the integrated potentiometer.
It is ideal for use as a signal source or excitation source in tests and experiments, having wide applications in production and technology. The generator is perfect for generating the control signal of motors, dimmers and speed control systems in general.
The module comes in a plastic case for protection and safe use. and is equipped with a high-definition LCD screen for clear viewing of the parameters.
Supports UART for easy integration into controlled systems.
It allows adjusting the frequency and filling factor, being easily adaptable for a wide range of applications.
The module keeps its last settings in memory when the power is interrupted.
It works in two selectable modes: Normal Mode and Precision Mode for fine adjustments. The Normal mode allows adjustment between 1Hz and 150KHz, rotating the encoder in accelerated mode leading to a faster change of parameters. The Precision mode instead allows adjustment between 1Hz and 15KHz.
It is equipped with a setting lock function to prevent accidental modification. The blocking is done by long pressing for 5 seconds on the encoder.
includes ON/OFF button for activating or deactivating the PWM output.
