Feature: 1. CLEAR DISPLAY: With liquid crystal display, the current mode and parameters at a glance, very clear, simple and practical, support key trigger control, high and low level trigger, switch quantity control, suitable for most occasion 2. AUTOMATIC DATA STORAGE: All parameters are automatically saved after being set, so they will not be lost during shutdown 3. GENERATED SIGNAL: The signal generator is a device that produces electrical signals of various frequencies, square waves, pulses and output levels 4. SUPPORT DUAL MODE: Come with PWM mode and PULSE mode, used as test signal source or excitation source, very practical 5. EFFECTIVE PROTECTION: One button pause function, with reverse connection protection, reverse connection no burning, support UART data upload and parameter setting Specification: Item Type: PWM Pulse Frequency Generator Operating Voltage: DC6V-30V Frequency Range: 1Hz to 150KHz Frequency Accuracy: 2% Timing Range: 0.01 seconds (minimum) ~ 9999 minutes (maximum) adjustable continuously Output Capacity: Can control DC 30V 10A or AC 220V 5A within the device Static Current: 15mA Working Current: 50mA Operating Temperature: -40-85℃ Trigger Signal Source: High level trigger(3.0V~24V), low level trigger(0.0V~0.2V), switching control(passive switch) Uses: Widely used in production practice and technology. Package List: 1 x PWM Pulse Frequency Generator Note: After all parameters are set, long press the setting button to save the parameter setting and exit the setting interface.
