Features: Description: This signal generator is a device that provides electrical signals at a variety of frequencies, square wave, pulse and output levels. It supports dual mode: PWM mode and PULSE mode. The two modes can be switched at any time.It is used as a signal source or excitation source for testing. Widely used in production practice and technology. Two modes can be selected: PWM mode - frequency (continuous), duty cycle, Pulse number is not adjustable, continue to send waveform; PULSE mode - positive pulse width time, negative pulse width time, delayed start time, and adjustablenumber of pulses. Can combine the driver to realize dimming, speed regulation, control solenoid valve, etc. Wide voltage input 3.3-30V, with anti-reverse protection, 5.08mm terminal wiring. Specifications: Model: PP1K Color: Black Material: Plactic&Metal Working Voltage: 3.3V-30V Frequency Range: 0Hz-150KHz Duty Cycle Range: 0-100% Number of Pulses: 1-9999 Signal Loading Capacity: 30mA.
