DROK Signal Generator, DC 3.3-30V Function Generator 5-30mA LCD Display PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave Signal Generator

DROK Signal Generator, DC 3.3-30V Function Generator 5-30mA LCD Display PWM Pulse Frequency Duty Cycle Rectangular Wave Square Wave Signal Generator

• PARAMETER ---- operating voltage range DC 3.3v~30v; frequency range 1Hz-150kHz; output current 5-30mA; duty cycle range 0-100%.
• APPLICATION ---- as square wave signal generator for experimental development; as square wave signal generator for motor driver; as adjustable pulse generator for MCU; as pulse generator, control related circuits (PWM dimming, speed regulating).
• SERIAL COMMUNICATION ---- support serial communication, TTL level.
• DATA AUTO STORAGE ---- all parameters will be saved automatically after setting and therefore won't lose when power off.
• OTHER FEATURES ---- with LCD display to display frequency and duty cycle value; with case; PWM output, can set frequency and duty cycle separately by buttons; frequency value is divided into 4 range and switched automatically, with high precision.

<strong>Parameter:</strong><br /> 1. Working voltage: DC 3.3v~30v<br /> 2. Frequency range: 1Hz~150kHz (divided into 4 ranges);<br /> 3. Frequency precision: 2% of each range;<br /> 4. Signal load capacity: output current is about 5-30mA;<br /> 5. Output Amplitude: PWM amplitude equal to the input voltage value<br /> 6. Environment Temperature Range: -20~+70℃<br /> 7. Duty cycle range: 0-100%.<br /> <br /> <strong>Application:</strong><br /> 1. As square wave signal generator for experimental development; <br /> 2. As square wave signal generator for motor driver;<br /> 3. As adjustable pulse generator for MCU; <br /> 4. As pulse generator, control related circuits (PWM dimming, speed regulating).<br /> <br /> <strong>Setting Parameters:</strong><br /> There are 4 independent buttons on the module for setting the frequency value and the duty cycle value. <br /> Supports short press (increase or decrease one unit by one unit) and long press (fast increase or decrease).<br /> All setting parameters will be saved when powered off to achieve data guaranteed.<br /> <br /> <strong>Frequency Display Instruction:</strong><br /> The frequency is divided into 4 ranges and switched automatically.<br /> 1. XXX (without decimal point): minimum unit is 1Hz, value range is 1Hz~999Hz.<br /> 2. X.XX (the decimal point is in the hundred digit): minimum unit is 0.01kHz, value range is 1.00kHz~9.99kHz.<br /> 3. XX.X (the decimal point is in the ten digit): minimum unit is 0.1kHz; value range is 10.0kHz~99.9kHz.<br /> 4. X.X.X (full decimal point): the minimum unit is 1kHz; the value range is 1kHz~150kHz<br /> <em>e.g.</em> Frequency displays 100 represents 100Hz; displays 1.01 represents 1.01kHz; <br />                       displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHz<br /> <br /> <strong>Package Included:</strong><br /> 1x Signal Generator<br />
