- Q:Is the switching power supply and switching power supply the same?
- 24-volt switching power supply and 24-volt switching power supply is the same.
- Q:Can DC power supply be used as a charger for lithium batteries?
- Plus a current limiting resistor can be. Lithium battery to bring a protective plate, will automatically turn off after charging.
- Q:Power supply 4.5v can drive 3.6v lithium battery
- it is recommended:
1, carefully measure the output voltage of the regulated power supply.
2, if it is 4.5 volts, easy to transform the output can be connected to a "germanium diode" (its forward conduction voltage is 0.2 ~ 0.3V), will make the output voltage is basically reduced to the appropriate.
- Q:What is the meaning of the regulator accuracy?
- Regulator accuracy refers to the output voltage fluctuation range is smaller, the higher the accuracy, such as electricity is very unstable, about what low, high precision regulator can be controlled within a safe range, like the computer this Precious equipment requires high precision.
- Q:What is the use of negative pressure power supply output negative pressure
- Most analog amplifiers have negative voltage, and some digital circuits also use negative voltage. The amount of negative voltage, multimeter hit DC voltage DC block, red pen on the ground, black pen on the negative voltage can be measured.
- Q:With the transformer why use DC power supply
- The transformer output is AC, must be rectified into DC to use; In addition, the rectification is only the direction of the DC, the size will change over time, so some of the voltage fluctuations in the case of strict control but also after the rectification Filter circuit and voltage regulator circuit,
- Q:Design DC power supply,
- LM317 can output positive adjustable voltage
LM337 can output negative adjustable voltage
Both of these can meet your input voltage, output voltage range requirements.
- Q:Will the DC power supply and DC constant current source of the respective characteristics
- First, the DC power supply characteristics:
1, DC power supply output display: the output voltage and current LED display;
2, DC power supply using 19-inch standard size, can be combined to put in a variety of work platforms and racks;
3, small size, light weight, energy efficient;
4, constant voltage constant current: the output constant voltage constant current automatic switching, voltage and current values of continuous linear adjustment;
5, protection: overvoltage protection, overcurrent protection, over temperature protection, undervoltage protection, overload protection;
6, short circuit characteristics: the machine working state for a long time short circuit;
7, external compensation: the machine optional external compensation, can reduce the output loop due to a longer pressure drop;
8, overvoltage protection value: the output over pressure protection value can be protected, cut off after the protection output and lock, re-boot recovery;
9, communication function: optional special data interface, and other equipment data connection control, or with the PLC connection;
10, DC power supply external control function: optional 0-5V or 4-20mA signal control power supply output voltage and current;
11, a timer function: optional timer switch function.
- Q:What is the difference between DC regulated power supply and AC regulated power supply?
- DC power supply is a direct current, in the oscilloscope showed a linear waveform, used in the requirements of the DC voltage and current circuit
AC power supply output is AC, oscilloscope on the sine wave, used in the requirements of constant voltage, and a certain frequency of the circuit.
Your question is not very clear, I can only ask you to ask so much
- Q:What is the regulated power supply?
- That is, through the rectifier, filter to provide the required stable voltage power supply device
