The basic components of a linear regulated power supply are
Explosion-proof Voltmeter
Explosion-proof electrostatic voltmeter is in the absorption of domestic and foreign advanced electrostatic instrumentation on the basis of the majority of users for more than 10 years and many times to improve the new high-performance, low-priced electrostatic voltmeter (electrostatic potential meter). The meter has good explosion-proof performance, and the explosion-proof mark is ExiaⅡCT6, which can be used in all kinds of explosive gases (such as petrol, 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 body and other electrostatic potential. It can also measure the potential of liquid surface and test the performance of anti-static products. Widely used in petroleum, chemical, oil depot, fire, electronics, national defence, aerospace, natural gas, printing, textile, printing and dyeing, rubber, plastics, spraying, medicine and other scientific research, production, storage and transportation ** management departments in the measurement of static electricity. It is the ideal instrument for on-site electrostatic detection.
Linear regulated power supply is a relatively early use of a class of DC regulated power supply. Linear regulated DC power supply is characterised by: the output voltage than the input voltage is low; fast response time, the output ripple is small; low noise generated by the work; low efficiency (now often look at the LDO is to solve the problem of efficiency and the emergence of); heat (especially high-power power supply), indirectly to the system to increase the thermal noise.
Linear regulated power supply by the adjustment tube, reference voltage, sampling circuit, error amplification circuit and so on several basic parts. It may also include some other parts such as protection circuits, start-up circuits and so on.
