Brand

Model

Feature:
1. Great Control: This machine can generate square wave pulse frequency signal, which enables easy control on equipment.
2. Working Modes: Designed to have normal mode and fine mode, and the 2 working modes have different working frequency.
3. Clear Display: LCD screen ensures clear viewing on the date, making the operation and adjustment much more convenient.
4. Broad Utility: Allows for wide application in experiment, motor driving, MCU, PWM controller and so on, very useful.
5. Simple to Use: Has locking function, can also automatically save all the data after setting, and many other functions.

Specification:
Item Type: Frequency Generator
Material: PCB + ABS + LCD
Application: Square Wave Signal Generator
Model: XY-PWM1
Working Voltage: DC 3.3V-30V
Frequency Range: Normal Mode: 1Hz-150kHz; Fine Mode: 1Hz-15kHz. 
Frequency Accuracy: 2% in each range. 
Signal Load Capacity: The output current is about 5-30mA. 
Output Amplitude: The PWM amplitude is equivalent to the input voltage value. 
Working Temperature: -20℃~+70℃
Normal Mode Frequency Range: 1Hz-150kHz
Normal Mode Duty Cycle: 00 to 100%
Normal Mode Duty Cycle Stepper: 1%
Fine Mode Frequency Range: 1Hz-15kHz
Fine Mode Duty Cycle: 00.0 - 100%
Fine Mode Duty cycle Stepper: 0.1%
Application: 
1. As a square wave signal generator for experimental development;
2. As a motor driven square wave signal generator;
3. As an adjustable pulse generator for MCU; 
4. As a pulse generator, it controls related circuits (PWM dimming, speed adjustment). 

How to Use:
Frequency Display Description:
1. The frequency is divided into 4 ranges and switches automatically. 
2. XXX: The minimum unit is 1Hz, and the value range is 1Hz~999Hz. 
3. X.XX: The minimum unit is 0.01kHz, and the value range is 1.00kHz~9.99kHz. 
4. XX.X: The minimum unit is 0.1kHz; the value range is 10.0kHz~99.9kHz. 
5. X.X.X: The minimum unit is 1kHz; the value range is 1kHz~150kHz. 
6. For example, the frequency display 100 means 100Hz; display 1.01 means 1.01kHz; display 54.1 means 54.1kHz; display 1.2.4 means 124kHz. 

Package List:
1 x Frequency Generator

Note:
Please pay attention to electricity safety when using it.
