EC Buying Function Signal Generator, ZK-PP2K PWM Pulse Frequency Generator, 1Hz-150KHz PWM Motor Speed Regulation/LCD Pulse Frequency Cycle Module Adjustable Driver Module/PWM Signal Generator
- ★ZK-PP2K PWM/pulse signal generator product introduction: This series of products are PWM and pulse signal generators. There are PWM mode and pulse mode. Only one mode can be used at a time, but the two modes can be switched at any time.
- ★Product Specifications: 1.Working voltage:3.3~30V (note that the positive and negative poles should not be reversed, otherwise it may burn) 2.Frequency range:1Hz~150KHz, the accuracy is about 2%. Motor speed regulation generally chooses 20KHZ 3.Duty cycle range:0-100%,1% step 4.Number of pulses:1-9999, or infinite (display '---' means infinite) 5.Delay output time:0.000s-9999s, the minimum can be set to 1ms 6.Positive and negative pulse width length:0.000s-9999s, the minimum can be set to 1ms
- ★Product Highlights: 1. It can directly drive loads such as LEDs, motors, solenoid valves, etc. 2. Two modes can be selected: PWM mode - one frequency (continuous), duty cycle. Note that switching times cannot be set in this mode, always, cyclically on and off; PULSE pulse mode 1 - positive pulse width time, negative pulse width time, power-on delay start time, and switching times are adjustable. 3. With the start and stop button, 4. Wide voltage input 3.3-30V,5.08mm terminal wiring
- ★Key operation instructions: 1. MOS switch type output, pay attention to no waveform, can directly drive the motor solenoid valve, etc. 2. When the number of switches reaches the set value, the output will be automatically stopped, and 'OUT' will disappear. 3. Press the ON key to control the presence or absence of the switch, and the disappearance of OUT means the output is turned off. 4. Power on and restart or ON key to turn on the output, and recalculate the switching times.
- ★Application scenarios: 1. PWM signal generator, square wave rectangular wave signal generator. 2. Used to generate square wave and rectangular wave signal to control DC motor or stepper motor driver; used for servo motor, stepper motor, substitute PLC pulse, etc. 3. ZK-PP2K can be matched with the driver to realize dimming, speed regulation, control solenoid valve, etc. ZK-PP2K can directly drive loads such as electric light motor solenoid valve.

Schumann Waves Generator,Schumann Resonance 7.83Hz Frequency Generator,Ultra-Low Frequency Pulse Generator Resonator,Schumann Wave Enhancer-Nature's Frequency 1 Pcs
- Power Range:The frequency of this product can be adjusted from 0.01Hz to 20000Hz, corresponding to five different brain waves in the human brain. Among them, the sleep wave δ wave is 0.5 - 3.5Hz; the drowsy wave θ wave is 4 - 7Hz; the relaxation wave α wave is 8 - 13Hz; the stress wave β wave is 14 - 30Hz.
- High-Quality Materials:Made of ABS material, it is impact-resistant, environmentally friendly, heat-resistant and low-temperature resistant. Internally equipped with high-stability frequency acquisition components, pulse chips, accurate correction capacitors, precise multi-turn adjustable resistors and shielded solid capacitors. The newly optimized circuit design has excellent performance.
- Schumann Resonance:The Schumann resonance spectrum is in the ELF band with a frequency of about 8Hz. The frequency of the hippocampus in the mammalian brain is also 7.83 hertz. Therefore, Schumann resonance is called "the brain wave of the earth" and "Nature's Frequency". Lightning anywhere on the earth will excite the electromagnetic oscillation of the resonant cavity and generate natural electromagnetic waves, that is, Schumann waves, which are about 8HZ.
- Silent Relaxation Experience:The product has no sound. Please choose and purchase carefully. In the Schumann wave environment, it is like being in nature, which can relax the body and mind and is very suitable for yoga meditation and sound healing. Reduce unconscious thinking activities in the mind, feel calm and stable, be in a pleasant and relaxed mood, and easily enter a meditative sleep state.
- Origin Explanation:We also call it the Nikola generator because Nikola Tesla first discovered and observed this phenomenon in Colorado Springs as early as 1899. Schumann systematically described this phenomenon in 1952. The main electromagnetic background of resonance is in the electromagnetic wave spectrum from 3HZ to 60HZ, and peaks appear near 7.83Hz (fundamental wave) and at 14.3, 20.8, 27.3 and 33.8Hz. And this frequency will be affected by ionospheric disturbances induced by the sun, temperature, humidity and other influences.
