Basic components of linear regulated power supply
The explosion-proof electrostatic Voltmeter is a new type of high-performance and low-cost electrostatic Voltmeter (electrostatic potentiometer) that has been used and improved by users for more than 10 years on the basis of absorbing advanced electrostatic instruments at home and abroad. This instrument has good explosion-proof performance, and the explosion-proof label is Exia Ⅱ CT6. It can be used in various explosive gases (such as gasoline, Carbon disulfide, municipal gas, ethylene, acetylene, hydrogen, benzene, etc.).
This linear regulated power supply instrument is suitable for measuring the electrostatic voltage (potential) of charged objects, such as conductors, insulators, and human bodies. It can also measure liquid level potential and detect the performance of anti-static products. Widely applicable for measuring static electricity in scientific research, production, storage and transportation management departments such as petroleum, chemical engineering, oil depots, fire protection, electronics, national defense, aerospace, natural gas, printing, textile, printing and dyeing, rubber, plastics, spraying, pharmaceuticals, etc. It is an ideal instrument for on-site electrostatic detection.
Linear regulated power supply is a relatively early type of DC regulated power supply. The characteristics of linear regulated DC power supply are: the output voltage is lower than the input voltage; Fast response speed and small output ripple; Low noise generated by work; Low efficiency (LDO, which is often seen nowadays, appears to solve efficiency problems); High heat generation (especially high-power power sources) indirectly increases thermal noise to the system.
The linear regulated power supply consists of several basic components, including an adjustment tube, a reference voltage, a sampling circuit, and an error amplification circuit. In addition, it may also include some parts such as protection circuits, starting circuits, etc.
