- Q:What is the regulated power supply?
- That is, through the rectifier, filter to provide the required stable voltage power supply device
- Q:DC power supply function is?
- Is the AC voltage through the rectifier regulator, the final output stable DC voltage, according to the power quality, ripple factor can be very small.
- Q:With a computer power supply how to make a separate power supply for other electrical appliances?
- 5, PS-ON (green line):
Responsible for the operating system management power switch, is a motherboard signal, and + 5VSB together referred to as soft power. Less than 1V when the power is turned on, greater than 4.5V when the power off, the realization of software switching machine, the network remote wake-up function (set wake-up time, through the keyboard boot) (and GND then short-circuit can start the power supply)
6, -5V (white line):
(Negative voltage rarely used, such as SFX removed -5V)
7, -12V (blue):
PG signal (Power Good, gray line, + 5V signal (+ 3.0 ~ + 6.0V)): before the system starts, the power supply (0.1 seconds to 0.5 seconds after the power is turned on to issue the signal) for internal inspection and testing, To the motherboard a signal, so the power is controlled by the power supply on the motherboard monitoring components. PG signal is very important, even if the output is normal, if there is no PG signal, the motherboard still can not work; if the PG signal timing is not right, will open the machine.
- Q:Siemens CNC system 810D what regulator power supply good? Or is it good?
- The Voltage regulator wide range of industrial, mechanical and electrical equipment and other large range. Regulator classification is only regulator accuracy, reaction time, work physics is different. There is also a question to tell you that the Hills UPS in China really few agents, are generally anti-licensing or OEM traders up to (professional industry said). If you are a Siemens system, may wish to consider looking for manufacturers to do with Siemens - Mei Ze power to talk, a surname Yin (Yin), 27659789-8009, people say. Service tracking fast. (I was his client). But if it is the original Siemens, may be equipped with a stable. May be equipped with a 20KVA. Because you have to take into account the momentary impact current of the machine. hope this helps.
- Q:Design DC power supply,
- Directly to buy a test of the power supply, but also their own design plate, trouble
- Q:What is the use of negative pressure power supply output negative pressure
- It depends on how you use it! General amplifier circuit used more.
- Q:How the DC regulated power supply outputs a negative voltage
- 1, the power supply is the two output terminals to negative as a reference, you can think it is a positive power supply, with positive as a reference, it can be considered a negative power supply.
- Q:Regulated power supply and load configuration
- 5, the power supply products can not be long-term full load with the load operation, must be in the power matching ratio on the left a certain degree of margin, generally to maintain a 30% margin more appropriate.
6, the power supply is stable for the load to provide a stable AC power supply or DC power supply electronics. Including AC power supply and DC power supply two categories.
- Q:On the 1.2V DC power supply problem
- The simplest is the diode buck, but the load current changes in the larger case, the stability is not too high.
The best is to use MOS regulator for the regulator, the circuit is slightly more complex.
- Q:Strange op amps and trips made of adjustable regulated power supplies, how does it work and where is it?
- I was the first time I saw this structure, I understand this:
LM338 - 5.0 is a precision 5V voltage reference, the dynamic internal resistance is very low, the typical value is 0.6Ω, op amp LM308 is the emitter follower connection, 2,3,6 feet equal, that is, V2 = V3 = V6 = 5V, Rs and triodes constitute a parallel regulator circuit, and the op amp is the controller.
Vin ↑, V3 ↑, V6 ↑, Io ↑ (op amp output current), I7 ↑ (op amp supply current), Ie ↑, URs ↑, Uout ↓.
