An oscillator is an energy conversion device that converts DC energy into AC power with a certain frequency. The circuit that constitutes it is called an oscillating circuit. The oscillators can be mainly divided into two types: a harmonic oscillator and a relaxation oscillator.
The development of the oscillator is mainly based on the requirements of the international and domestic markets, and is suitable for laboratories and pilot laboratories of chemical industry such as paints, dyes, paints and inks; the ideal for small dispersion, sanding and ball milling that is urgently needed by scientific research units. Test Instruments.
installation
1. The "oscillator" adopts a low-leg spring frame bottom, which has a good stability effect on the body. The user only needs to place four springs in the spring seat on the bottom of the body and perpendicular to the ground.
2. Please confirm whether the voltage and frequency used by the instrument are consistent with the voltage and frequency supplied by your company.
3. The power supply of the equipment is three-phase, 380V, 50Hz. It should be equipped with electric switch and 3A fuse, and then connected with the equipment. Note that the equipment casing must be grounded reliably before use to avoid danger.
4. Be sure to ground the instrument and install it in a safe place.
5. When the instrument is not in use, please cut off the power to prevent accidents.
The role of the oscillator
The oscillator is simply a frequency source and is typically used in phase-locked loops. In detail, it is a device that can convert DC power into AC power without external signal excitation. Generally divided into positive feedback and negative resistance. The so-called "oscillation" implies the communication, and the oscillator contains a process and function that never oscillates to oscillate. Such a device can be converted from DC power to AC power, and such a device can be called an "oscillator."
Any communication or electronic system should have a normal range of level values ​​at some given point, and the components that adjust to normal levels are amplifiers and attenuators. The low level point is the noise introduction point, and the too high level point will cause overload, which causes the amplified component to have intolerable nonlinear distortion. It is not difficult to understand the role of the attenuator. The attenuator is available in both fixed and variable versions.
PMG generator - Permanent Magnet Generator. It's AC generator, alternator, not DC. The efficiency of this kind generator is not bad, around 50% ~ 85%. And power range very wide, from 50W, 100W to 100KW, 200KW, voltage is 12V / 24V / 48V / 96V / 220V / 380V, etc. These generators could be used on wind turbine or something else DIY.
