XY-PWM Dual Frequency Generator 0-150KHz

Features:

• Two independent PWM outputs, allowing separate adjustments for frequency and duty cycle.
• Frequency is divided into three ranges.

XXX (no decimal point): Minimum unit is 1Hz, range is from 1Hz to 999Hz.

XX.X: Minimum unit is 0.1KHz, range is from 0.1KHz to 99.9KHz.

X.X.X.: Minimum unit is 1KHz, range is from 1KHz to 150KHz.

Duty cycle range: 0-100.

All parameters are saved when powered off.

• Suitable for serial communication.

Specifications:

• Operating voltage: 5–30V, supports micro USB 5.0V power supply.
• Frequency range: 1Hz–150KHz.
• Frequency accuracy: ±2 %.
• Output current: 8–30mA.
• Output amplitude: presented 5V V-pp (adjustable).
• Operating temperature range: -30 ~ +70 °C.

Parameter Setup:

1. Short press the SET button to toggle between the display of 4 parameters (FR1:PWM1 frequency; dU1:PWM1 duty cycle; FR2:PWM2 frequency; dU2:PWM2 duty cycle); the corresponding parameter will blink before switching.
2. Pressing UP and DOWN buttons can change the current parameter.
3. 2-channel PWM is set to three types of frequency values; in frequency display mode, a long press on SET can perform a transition; 3 types of frequencies share duty cycle (XXX: 1Hz~999Hz; XX.X: 0.1KHz~99.9KHz; X.X.X.: 1KHz~150KHz).

Usage:

• To generate square wave signals for experiments and development.
• To generate square wave signals for stepper motor units.
• To generate adjustable pulses for MCU.
• To generate variable pulses for circuit control.
