Modular Power Supply -PWM Signal Generator Module Highlights Generic Brand PWM Signal Generator Module Description: The frequency and duty cycle of the LCD display are very clear. Two independent PWM generators can set frequency, duty cycle. The wide frequency range, high precision. Can serial communication. The frequency is divided into four ranges, automatic switching: 1. XXX (without decimal point): the smallest unit is 1Hz, and the value range is 1Hz ~ 999Hz. 2. X.XX (100-bit decimal point) is 0.01Khz, and the value range is 1.00Khz~9.99Khz. 3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz; and the range is 10.0KHz~99.9KHz. 4. XXX (ten-bit and 100-bit decimal point): the smallest unit is 1 kHz; and the range is 1KHz~150KHz. Frequency display: 100 indicates 100Hz PWM output 1.01 is the pulse of 1.01K PWM output 54.1 is the pulse of 54.1KHz PWM output 1.2.4 is the pulse of 124KHz PWM output. The duty ratio range: 0~100% specification: Working voltage: 3.3~30V Frequency range: 1Hz~150KHz Frequency accuracy: about 2% Signal load capacity: output current about 5~30ma Output amplitude : PWM amplitude is equal to supply voltage Ambient temperature: -20 ~ +70 ? Size: 5 x 4cm / 2 x 1.6inch Package Include: 1 Piece Signal Generator Module
