Feature: 1. This signal generator provides electrical signals at various frequencies, square wave, pulse, and output levels. It supports dual modes: PWM mode and PULSE mode, which can be switched at any time. It serves as a signal source or excitation source for testing and is widely used in production and technical applications. 2. Two modes are available: - PWM mode: continuous frequency and duty cycle adjustment; pulse number is not adjustable; continuously outputs waveform. - PULSE mode: adjustable positive pulse width, negative pulse width, delay start time, and number of pulses. 3. Can be used with a driver to enable dimming, speed control, solenoid valve control, and other functions. 4. Wide input voltage range: 3.3V–30V; includes reverse polarity protection; 5.08mm terminal block wiring. Specifications: Model: PP1K Color: Black Material: Plastic & Metal Working Voltage: 3.3V–30V Frequency Range: 0Hz–150kHz Duty Cycle Range: 0–100% Number of Pulses: 1–9999 Signal Load Capacity: <30mA Package Weight: 40g Package Size: 7.9 x 4.3 x 3cm Positive and Negative Pulse Width: 0.000s–9999s Package List: 1 x Signal Generator
