Description

BET PWM-G Series Frequency Square Wave PWM Generator module is a kind of pulse frequency, square wave, PWM signal simulation device. It outputs 2-channel independent pwm frequency signal, the duty ratio is adjustable. Output frequency signal range is 1Hz-1kHz-150kHz (Customized input is available), the min. input frequency is 1Hz, the max. frequency is 150KHz, it’s accordingly duty cycle range is 0-100. That pwm signal generator can be used to control and drive stepping motor, used as square wave generator to provide square wave signal source for meters, sensor, MCU or other devices, be applied in light and speed control and adjustment.

PWM Generator Module Highlights:
>> 2-channel independent PWM output, frequency and duty cycle adjustable.
>> High accuracy, wide frequency range.
>> Serial ports communication is available.

PWM Generator Applications:
>> Square wave signal generator to output square wave signal.
>> Used as deriving module to control stepping motor.
>> Output adjustable pulse for MCU.
>> Output adjustable pulse to control PWM circuit or adjust light and speed.

PWM Generator Parameters:
1. Operating Voltage: 5-30VDC, support micro USB 5.0V power supply.
2. Frequency range: 1Hz-150KHz.
3. Frequency accuracy: about 2% in each frequency range.
4. Signal load capacity: output current is in 8-30mA.
5. Output amplitude: default 5V Vp-p (can be changed by adding external power supply).
6. Operating temperature range: -30~+70℃.

7. 3-type frequency range:
A. XXX   (No decimal point): the min. unit is 1Hz, value range: 1Hz-999Hz.
B. XX.X  (Decimal point in tens position): the min. unit is 0.1kHz, value range: 0.1KHz-99.9KHz.
C. X.X.X. (Decimal point in each digit): the min. unit is 1kHz, vaule range: 1KHz-150KHz.
E.g.: LED Display 100 indicates PWM output pulse 100Hz.
LED Display 54.1 indicates PWM output pulse 54.1KHz.
LED Display 1.2.4 indicates PWM output pulse 124KHz.

8. Value range of duty cycle: 0-100 . The three types of frequency value range are in the same duty cycle. All the settings is saved in power off state.

PWM Generator Parameters Setting:
1. Short press【Set】button, switch four parameters displayed: FR1: PWM1 Frequency, dU1: PWM1 duty cycle; FR2: PWM2 Frequency, dU2: PWM2 duty cycle. The LED flashing before setting it.
2. Press 【Up】,【Down】Buttons to revise the current value.
3. 2-channel PWM signal output, 3-type frequency range preset in the same duty cycle: Long press 【SET】button to switch the frequency range: XXX: Range 1Hz-999Hz; XX.X: Range 0.1Khz~99.9Khz; X.X.X: Range 1KHz-150KHz.

PWM Generator Serial Ports Control:
