What are the Common AC Stabilized Voltage Power Supplies?

Jul 09, 2016

AC stabilized voltage power supplies are also called AC voltage stabilizer. With the development of electronic technology, especially after electronic computer technology is applied to various industries and scientific research fields, most electronic equipment require stable AC power supplies and direct power supply from grid has not been able to meet the demand. Then, the appearance of AC power supplies solved this problem. The following are the common AC stabilized voltage power supplies.

1.Ferromagnetic resonant AC voltage stabilizer-composed of saturable reactor and corresponding capacitor and with the characteristic of constant voltage volt ampere.

2.Magnetic amplifier type AC voltage stabilizer-the magnetic amplifier and autotransformer connected in series and using electronic circuit to change the impedance of the magnetic amplifier to stabilize the output voltage.

3.Sliding type AC voltage stabilizer-stabilize output voltage through changing the transformer’s slide contact location.

4.Induction AC voltage stabilizer-stabilize output voltage through altering the phase difference of transformer’s secondary and primary voltage.

5.Thyristor AC regulated power supply-using thyristor as power adjustment device. High stability, fast reaction and noiseless.

What’s Digital Multimeter?

Digital multimeter is a kind of digital measurement instrument which has many applications. The digital multimeterhas the function like ammeter, voltmeter, ohmmeter and others.
Digital multimater has the portable unit which used for basic fault diagnosis and bigger size unit which can be placed on workbench. It is the digital instrument during electrical measurements. It also has many special function such as measuring voltage, resistance and current. As the multi-purpose digital measuring instrument, it is usually used in physics, electric and electron measuring areas.

The Difference of Spectrum Analyzer

Compared with the traditional spectrum analyzer working principle, the most obvious change of modern sweep-frequency spectrum analyzer is AD sampling. It also realizes the digital signal treatment. As long as we purchase the matchable option, it will possess the function like vector signal analyzer, signal demodulation, communication measurement. So we can pay at lowest cost then can realize the most complete function of the spectrum analyzer.

The Design of the Modern Spectrum Analyzer

The spectrum analyzer has developed more and more functions under the modern technology, it usually adopt the software radio design. Through constructing the strong universality hardware platform, it can realize the software controlling the functions, which make the spectrum analyzer master to possess features of software definition instruments. We can through update the software to realize some other functions, such as receiver, power meter, frequency indicator, which extends the measure ability and application field.
