Product Description:

A versatile, panel-mountable PWM signal generator module designed for applications requiring precise control over pulse frequency and duty cycle. Operating within a voltage range of 3.3V to 30V DC, it delivers a square wave output with frequencies ranging from 1Hz to 150kHz and a duty cycle adjustable from 0% to 100%. The module features a clear LCD display and user-friendly interface, making it ideal for various electronics projects, motor control, and signal testing.

Key Features:

  • Output Frequency Range: 1Hz to 150kHz
  • Duty Cycle Range: 0% to 100%
  • Operating Voltage: 3.3V to 30V DC
  • Output Amplitude: Equal to input voltage
  • Output Current: 5mA to 30mA
  • Display: LCD screen showing frequency and duty cycle
  • Control Interface: Four push-buttons for frequency and duty cycle adjustments
  • Serial Communication: TTL interface supporting UART commands
  • Memory Function: Retains settings after power-off
  • Operating Temperature: -20°C to +70°C
  • Dimensions: 79mm × 43mm × 37mm
  • Panel Cutout Size: 76mm × 40mm

Control Modes:

  • Normal Mode: Frequency adjustable from 1Hz to 150kHz with 1% duty cycle steps
  • Precise Mode: Frequency adjustable from 1Hz to 15kHz with 0.1% duty cycle steps

Applications:

  • Motor speed control
  • LED dimming
  • Signal generation for microcontroller testing
  • Servo control
  • Laboratory experiments

Usage Notes:

  • The module's output is a square wave PWM signal with amplitude equal to the input voltage.
  • Ensure the connected load does not exceed the maximum output current of 30mA.
  • For higher current applications, use the PWM signal to drive an external transistor or MOSFET.
