DC Power Supply Manufacturer
Chargers can be brought on the plane, but the charging treasure on the rules, 1, charging treasure less than 20,000 mA can be carried over the security check on the plane. 2, more than 20,000 mA less than 32,000 mA must be approved by the airlines to bring on the plane. 3, the charging treasure...
Description
The earliest DC power supply is relatively simple, generally using a transformer, the AC utility into another need for alternating current, and then after a simple rectifier filter circuit, the output DC, this DC is not stable, the voltage will be changed with the load of the lightness of the changes in the input utility or high and low changes.
The simplest way to change AC to DC is: first rectify the AC voltage into a unidirectional pulsating voltage, and then filter the unidirectional pulsating voltage is converted to a DC voltage with a small amount of ripple, if the requirements of a higher quality DC voltage, and then regulate the voltage so that it is more stable and smaller ripple. This operation can be completed AC to DC operation, that is, the basic principle of AC to DC power supply.
Industrial AC to DC device is usually called a rectifier. Rectifier is a rectifier, simply put, is the alternating current (AC) into direct current (DC) device. It has two main functions: first, to turn alternating current (AC) into direct current (DC), which is filtered and supplied to the load, or to the inverter; second, to provide charging voltage to the battery. Therefore, it plays the role of a charger at the same time.
The characteristics of DC power supply:
1. DC voltage and current regulator power supply line form for linear series adjustment type, with high stability accuracy, low ripple voltage and other characteristics.
2. the use of reference voltage suspension iteration technology, the output voltage can be adjusted from zero volts to the rated value; output current can be preset from zero amperes to the rated value.
3. Stabilized voltage (C.V), stabilized current (C.C) state automatic conversion.
4. Small power products adopt relay to change the AC voltage at both ends of rectifier bridge to reduce the tube voltage drop of regulator tube and improve the efficiency of the whole machine.
5. High voltage and high current products adopt SCR phase-shifting pre-regulation technology, which improves the efficiency of the whole machine.
6. optional output compensation function (with external sampling function), especially suitable for DC motors, electronic instruments, electrical products testing and inspection applications.
7. output over-voltage protection voltage value adjustable, when over-voltage output, the power supply automatically shut down the output and lock.
8. Professionally designed pipeline cooling technology effectively reduces the temperature rise of the whole machine, improves the product and prolongs the service life of the product.
So it is also important to choose the brand of switching power supply, want to know more about switching power supply information, you can consult Xiamen Eahunt Electronics.
