PREMIUM ELECTRONIC COMPONENTS: Crafted with high-quality materials, this Schumann Wave Generator ensures durability and optimal performance. Ideal for professionals requiring dependable tools in electronics, automotive, or industrial applications. USER-FRIENDLY DESIGN: This generator is engineered for simplicity, featuring an easy installation process and straightforward instructions. It's designed to be accessible for both professionals and hobbyists, making it a versatile addition to any toolkit. The signal generation unit has been redesigned, incorporating frequency locking and waveform shaping technologies. Most current Schumann wave generators, regardless of the circuit used, operate in free oscillation mode, and the waveform is pre-adjusted. Afterward, they are set free. During this free-flowing process, the frequency can drift uncontrollably, and the waveform can also change due to various environmental interferences. Version 7.83-6's improved design eliminates frequency drift; if it does, it's pulled back to maintain a constant 7.83 Hz. No worries about waveform degradation; forced shaping is implemented. All of this is dynamically performed within the chip. Voltage:DC12V Plug Type:EU Plug,it applies to Indonesia, Germany, France, Spain, Italy and so on.
