Dual System Pwm Pulse Frequency Signal Generator Duty Cycle Adjustable Module Square Wave Rectangul

Module stressed: 1. The dual mode, the duty cycle is 0.1% good model; The lock function, prevent wrong operation;2. The frequency and duty cycle, LCD LCD is very clear, using encoder potentiometer to adjust, very convenient; PWM output frequency and duty cycle can be set separately;3. The module is described: PWM output, frequency and duty ratio can be separately;4. The duty cycle of the upper and lower limits can be set up; KPWM switch, and PWM output can be turned on and off a key;5. The wide frequency range and high precision; Serial communication is possible;model: XY-KPWMNormal mode: Frequency range 1 hz~000~150 KHZ duty cycle, duty ratio 1%Good mode: Duty cycle 1 hz to 15 KHZ range of 00.0~0.1% duty cycleIs divided into four frequency range, automatic switch: 1. XXX (no decimal point): a small unit is 1 hz, value range is 1 hz ~ 999 hz.2. X. (decimal point in ), small unit 0.01 KHZ, and the value range is 1.00 KHZ to 9.99 KHZ.3. .Decimal point X (10): a small unit 0.1 KHZ; Values range from 10.0 KHZ to 99.9 KHZ4. 7.0.x.x.X (decimal point in dozens, hundreds of): a small unit 1 KHZ; Range of values is 1 KHZ to 150 KHZSuch as frequency display: 100 means that the PWM output 100 hz pulse54.1 54.1 KHZ PWM output pulse means1 means that the PWM output 124 KHZ pulsesAll save the parameter set to turn it off.parameters: Working voltage: 3.3 ~ 30 v.The frequency range: 1 hz ~ 150 KHZ normal mode; A good pattern 1 hz to 15 KHZThe frequency accuracy: precision in every range of about 2%Load capacity: The signal can be about 5 ~ 30 ma output currentThe output amplitude, pulse width modulation amplitude is equal to the power supply voltage The environment temperature: - 20 ~ + 70 .Material: plasticcolour: grey blackPackage Contents: 1 x Signal GeneratorOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +\/- 1-3cm.
