Pamata raksturlielumi un vajadzības of a DC kontrolēta barošana padeve
An elektronika ierīce kas var nodrošināt a stabils līdzstrāva jauda padeve to a slodze. The power supply of the DC stabilizēts power supply is galvenokārt maiņstrāva barošana padeve. Kad spriegums of maiņstrāva jauda padeve vai slodze pretestība izmaiņas, the DC output spriegums of the spriegums stabilizators būs paliks stabils. DC stabilizēts jauda padeve Ar attīstību elektroniska iekārta virziens augsts precizitāte % 2c augsta stabilitāte un augsta uzticamība % 2c augstas prasības ir uz priekšu jauda piegāde elektroniska iekārta.
Ievads līdzstrāva regulēta barošana barošana padeve
In today's society, people greatly enjoy the convenience brought by electronic equipment, but any electronic equipment has a common circuit - the power circuit. From supercomputers to pocket calculators, all electronic devices must be supported by power circuits to work properly. Of course, the style and complexity of these power supply circuits vary widely. The power circuit of a supercomputer is itself a complex power system. Through this power system, all parts of the supercomputer can receive continuous and stable power supply that meets various complex specifications. A pocket calculator is a much simpler battery-powered circuit. But don't underestimate this battery power supply circuit. The relatively new circuit is fully equipped with advanced functions such as battery energy reminder and power-down protection. It can be said that the power circuit is the basis of all electronic equipment, without the power circuit, there would be such a wide variety of electronic equipment.
1. The output voltage value can be set arbitrarily and work normally below the rated output voltage value.
2. The steady current value of the output current can be set patvaļīgi zem the rated output current value and work normal.
3. The voltage and current status of the DC regulated power supply can be automatically switched and have corresponding status indications.
4. Precīzs displejs un identifikācija ir nepieciešami priekš izejas sprieguma un strāvas vērtībām.
5. For DC regulated power supplies with precise requirements for the sum of output voltage and current, generally multi-turn potentiometers and voltage and current fine-tuning potentiometers are used, or direct digital input is required.
6. There must be a complete protection circuit. The DC regulated power supply should not be damaged when a short circuit occur at the output end or in in an abnormal working state, and it can work normal normally immediately immediately after the abnormal situation is eliminated.
