2 Channel Dual Independent PWM Generator

2 Channel Dual Independent PWM Generator Price in Pakistan

• Two independent PWM generators can set the frequency, duty cycle;
• The wide frequency range, high accuracy;
• serial communication option
• Frequency is divided into three ranges:
• XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz;
• XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KH
• X.X.X. (there are three decimal point): the smallest unit is 1Khz; the range 1KHz ~ 150KHz
• Frequency display example:
  “100” indicates that the PWM output pulse of 100Hz;
  “54.1” indicates that the PWM output pulse of 54.1KHz;
  “1.2.4.” Indicates that the PWM pulse output 124KHz
• Duty Cycle in the range: 0 to 100;
• Three frequencies duty cycle is the same, all the parameters non-volatile.
• Working voltage: 5–30V, support micro USB 5.0V power supply;
• Frequency range: 1Hz ~ 150KHz;
• The frequency accuracy: ± 2%;
• Output Current: <30mA;
• Output amplitude: Default 5Vp-p (settable);
• Operating temperature range: -30 ~ + 70 °.

Settings:

• Module has three buttons [Set], [Up], [Down];
• Press [Set] key to switch the display four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before the handover parameters, there will be corresponding parameter name flash.
• Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast).

Scope

•  As square wave signal generator which generates a square wave signal;
• to provide a signal to the stepping motor driver;
• Adjustable pulse generation for chip use;
• produce variable pulse signal, the control-related circuit (PWM dimming, speed).
• Fifth, the serial control
• Baud rate: 9600 bps
  • Data bits: 8
  • Data bits: 8
  • Stop bits: 1
  • Parity bit: none
