DC 4-30V Single Signal Generator PWM Pulse Frequency Adjustable Cycle LCD Screen 1Hz ~ 160 kHz 5-30mA Signal Generator

Description: The PWM signal generator is a device that provides electrical signals at a variety of frequencies, square waves and output levels. it is used as a signal source or excitation source for tests. Widely used in production practice and technology. Features: -With outer shell; - Led screen; - Admits frequency adjustment; - Admits the adjustment of the service cycle; -High precisio'n detection; -Supports the shutdown memory function; -PWM output of 1 channel. Specifications: Work voltage: DC 4.0 V-30 V; Frequency range: 1Hz 160 kHz; Frequency accuracy: 2%; Service cycle range: 0.00% -100%; Output current: around 5-30 mA; Output amplitude: equal to input voltage; Size for the screen: 48 * 29 * 22mm; Frequency set range: Enter the configuration interface by pressing the "SET" button in the normal operating state to select the frequency range. change the frequency range automatically. (The screen will flash automatically, the first line is the frequency, the second line is the service cycle) Pay attention to the position where the decimal point moves when the button is pressed. Screen xxx. Without a decimal point, the minimum frequency is 1Hz. The frequency range is 1Hz 999Hz. Screen 'X. XX '. The decimal point is the penultimate, the minimum frequency is 0.01khz. The frequency range is 1.00 kHz 9.99 kHz. Screen xx. x. the decimal point is the third last, the minimum frequency is 0.1khz. The frequency range is 10.0 kHz 99.9 kHz. Screen x. the decimal point is fully lit, the minimum frequency is 1 kHz. The frequency range is from 1 kHz to 160 kHz. For example: Screen 109: the PWM output frequency is 109Hz; Screen 1. 39 ": the PWM output frequency is 1.39 kHz; Screen 27. 3 ": the PWM output frequency is 27.3 kHz; Screen "1. 3.4": the PWM output frequency is 134 kHz; Service cycle game range: Enter the configuration interface by pressing the "set" button in the normal operating state to select the service cycle. The range of the service cycle is 0.00% -100%. Use steps: 1. connect to the power supply; 2. Short press button to set the frequency or service cycle; 3. Short or long press button 'UP' or 'DOWN' to modify the frequency or service cycle; 4.flashes automatically for 6 seconds, the parameters are saved automatically; 5.connect to the load. Application: Generator of square wave signal, generating square wave signal for experimental development; It is used to generate a square wave signal that controls the motor controller; Generates adjustable pulses for use by the MCU; Attenuator; Speed regulator; Package includes: 1 x Signal Generator 1 x Cable 2 x DuPont male pair male line; Detail pictures:
