LED brightness adjustment, frequency, duty cycle can be adjusted. Motor speed adjustment, frequency and duty cycle can be adjusted. Drive the solenoid valve to pull and release, automatic cycle, delayed output, number of cycles (or infinite loop) can be set. Control equipment to turn on and off, perform switch fatigue tests, voltage drop and other tests to verify the reliability of the customer's equipment. Delayed start load, delay time can be set, after the delay it will turn on or intermittently.
3.2 PWM mode (the display has \"% \" for PWM mode) The factory setting is PWM mode, FREQ+ and FREQ- keys set the frequency, DUTY+ and DUTY- buttons set the duty cycle; short press the STOP button controls the signal output or stops, the stop output is 0, the screen displays \"OUT \" mark that There is output, otherwise it stops output; the default factory frequency is 1KHZ and the duty cycle is 50%.
If you want to switch to PULSE mode, long press the SET button (more than 6 seconds), do not release, you will see the screen change, \"% \" disappears, it is PULSE mode.
Color: As shown. material: plastic
1. Highlights: 1.1 can directly drive LED, motor, solenoid valve and other loads
Two modes can be selected:
PWM mode - frequency (continuous), duty cycle. Note that the number of pulses cannot be set in this mode, and the pulse is always output.
PULSE pulse mode - positive pulse width time, negative pulse width time, delayed start time on power-on, and number of pulses are adjustable.
With start and stop button, can control the output and stop of the signal
Wide voltage input 3.3-30V, 5.08mm terminal connection
2. Technical parameters:
2.1 Working voltage: 3.3~30V (note that the positive and negative poles must not be reversed, otherwise it may burn out)
2.2 Frequency range: 1Hz~150KHz, accuracy is about 2%. Motor speed control usually chooses 20KHZ
2.3 duty cycle range: 0-100%, 1% step
2.4 number of pulses: 1-9999, or infinite (display '----' stands for infinity)
2.5 delayed output time: 0.000s-9999s, minimum can be
