Product description

Parameter: Working voltage: 3.3V~30V, with anti-reverse protection. Frequency range: 1Hz~150KHz, accuracy about 1%. Duty cycle range: 0-100%, 1% stepping. Number of pulses: 1-9999, or infinite (display '----'stands for infinity). Delay output time: 0.000s-9999s, the minimum can be set 1ms. positive and negative pulse width length: 0.000s-9999s, the minimum can be set 1ms. signal loading capacity:less than 30mA. Output signal amplitude: amplitude is equal to the supply voltage. Product size:79mm*43mm*30mm Feature: PWM mode - frequency (continuous), duty cycle. Note that the number of pulses cannot be set in this mode, and the pulse is always sent; PULSE mode - positive pulse width time, negative pulse width time, delay start time, and number of pulses are adjustable. Package Includes: 1x PWM Signal Generator

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.
