Customer Service Warranty Service Product Description Description: HW-515 Micro USB DC 2CH Adjustable PWM Signal Generator Duty Cycle Pulse Frequency Module Board Digital LED Display Tube Descriptions: The frequency is divided into three ranges: XXX (without decimal point): the smallest device is 1 Hz, the range is 1 Hz ~ 999 Hz; XX.X (Decimal point in ten): The minimum block is 0.1 kHz; 0.1 kHz ~ 99.9 kHz XXX (there are Three decimal points): the smallest block is 1 kHz; 1 kHz ~ 150 kHz range Display frequency, for example: "100" means output PWM pulse 100 Hz; "54.1" means that the output of the PWM pulse is 54.1 kHz; "1.2.4". Indicates that the PWM pulse output is 124 kHz Duty cycle in the range: from 0 to 100; The three-frequency duty cycle is the same, all parameters are non-volatile. Parameter settings: The module has three buttons (set), (up), (down); Press (set) to switch the display with four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency PWM2; dU2: PWM2 duty cycle), before passing the parameters, there will be a corresponding parameter name flash. Press (up), (down) keys to change the current parameter value (long press can quickly add or subtract quickly). Two PWM each has three preset frequencies, frequency display interface, long press (set) key to switch between three types of frequencies, three kinds of frequency cycle is the same value. (XXX: 1 Hz ~ 999 Hz; XX. X: 0.1 kHz ~ 99.9 kHz; XXX: 1 kHz ~ 150 kHz,). Set PWM frequency "S1FXXXT": PWM1 XXX HZ Frequency Setting (001 ~ 999) "S1FXX. XT": Set the frequency of the PWM1 XX. X kHz (00.1 ~ 99.9) "S1F: XXXT": tuning the frequency PWM1 XXX kHz (0.0.1 ~ 1.5.0 ..) 'S1': PWM1 'S2': PWM2 'F': frequencies D: Duty cycle 'T'-final flag Install PWM Duty Cycle "S1DXXXT": Installing PWM1 Duty Cycle XXX; (001 ~ 100) "S2DXXXT": set PWM2 Duty Cycle XXX; (001 ~ 100) Setting a successful return: down; Setup failover: drop. Features: Two independent PWM generators can set the frequency, duty cycle; Wide frequency range, high accuracy; You can order a series of communication. Specifications: Operating voltage: 5-30V, support for micro USB 5.0 in power Frequency range: 1 Hz ~ 150 kHz Frequency accuracy: ± 2% Output current: <30mA Output Amplitude: default 5Vp-p (network) Operating temperature range: -30 ~ + 70 Size: 41*28mm/1.61*1.10" Thickness: 1.6mm/0.06" Serial control Transmission Rate: 9600 BPS Data bit: 8 Stop bits: 1 Parity: no Gas Pressure Regulator: No Scope: 1. As a square wave signal generator that generates a square wave signal; 2. To provide a signal to the stepper motor driver; 3. Adjustable pulse generator for the use of chips; 4. Variable pulse signal, a control circuit (PWM dimming, speed). Notes: 1. There may be slight size deviations due to manual measurement, different measuring methods and tools. 2. The picture may not show the actual color of the item because of different photographing light, angle and display monitor. Included: 1 X PWM Signal Generator pictures payment We accept PayPal.
