PWM Generator 1 Channel PWM signal generator module with frequency and pulse filling adjustment. We have one channel for which you can set the frequency and filling pulses. The PWM signal has an amplitude of 5V and is a signal of type PNP i.e. at the output is given 5V relative to the mass. Please note that the current output capacity of the outputs is at 20mA, if you need more current, you should add an output transistor! The system can be powered by 6-30V or by feeding 5V directly to the micro USB port. The generator works with frequencies: 1-999Hz (. xxx) 0,1-99,9kHz (. XX.X) 1-150kHz (. xxx) The system can be used, for example. for timing stepper motor drivers. Technical parameters: Supply Voltage 6-30VDC Current consumption up to 50mA Number of channels 1 Frequency control 1Hz-150kHz Filling adjustment 1- Output current capacity 20mA Operating temperature -20 to 60 C Dimensions 55x36mm Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
