Dual System PWM Pulse Frequency Signal Generator Duty Cycle Adjustable Module Square Wave Rectangular bBang

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-KPWM Normal 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 cycle Is 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 KHZ 4. 7.0.x.x.X (decimal point in dozens, hundreds of): a small unit 1 KHZ; Range of values is 1 KHZ to 150 KHZ Such as frequency display: 100 means that the PWM output 100 hz pulse 54.1 54.1 KHZ PWM output pulse means 1 means that the PWM output 124 KHZ pulses All 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 KHZ The frequency accuracy: precision in every range of about 2% Load capacity: The signal can be about 5 - 30 ma output current The output amplitude, pulse width modulation amplitude is equal to the power supply voltage The environment temperature: - 20 - and 70 . Material: plastic colour: grey black Package Contents: 1 x Signal Generator Only 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.
