Product Description

DESCRIPTION:

• PWM output, you can set the frequency, duty cycle;
• Frequency is divided into four ranges, automatic switching:
  1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
  2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
  3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
  4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
  e.g. frequency display: 100 indicates PWM output 100Hz pulse;
  1.01 indicates PWM output 1.01K pulse;
  54.1 indicates that the PWM output has a pulse of 54.1 kHz;
  1.2.4 indicates that the PWM output is 124 kHz pulse;

Duty cycle range: 0 ~ 100%;
All set parameters, power down save.

Module parameters:
1. Working voltage: 3.3 ~ 30V;
2. Frequency range: 1Hz ~ 150KHz;
3. Frequency accuracy: the accuracy in each range is about 2%;
4. Signal load capacity: the output current can be about 5 ~ 30ma;
5. Output amplitude: PWM amplitude equal to the supply voltage;
6. Ambient temperature: -20 ~ +70 °
