1. Product Description:
It often happens that the electrical equipment are damaged because of lack of power. The experts of power point out most 80% malfunctions of computer are caused by A.C. power supply directly or indirectly. So as to ensure the safe operation of electrical equipment, the power supply must be improved. Our products fulfill the requirements in such places for his spurious characteristic. Our products are suitable for the following fields: science department, university, corporation, hospital, broadcasting station, communication equipment, traffic system, test equipment and all automatic production equipment.
2. Product Characteristic:
A.C. Precision purity regulated power supply is our new, high characteristic electronic A.C. regulated equipment as KUPA doctor’s theory, combining Asymmetrical Digital Subscriber Loop colander net, which integrates multi-functions such as purity regulation and anti-disturbance. They are of wide range in regulation, fast speed in response, high precision in regulation etc.,to refrain all kinds of noise from power net and disturbance from peak.

4. Reference Picture:
- Q:Photovoltaic grid-connected system, with the inverter with the role of transformer. In the choice of inverter with a transformer and without a transformer, how should choose? That is the isolation, I do not quite understand. Who knows that high! Thank you!
- Inverter with a transformer is played a role in isolation, it can provide you with pure sine wave current, so that the PV grid-connected system can provide a more secure and reliable isolation.
- Q:Does anyone know the storyline to Transformers 2? A release date would also be great.
- The movie is called Transformers: Revenge of the Fallen. It comes out June 26th. Decepticon forces return to Earth on a mission to take Sam Witwicky prisoner, after the young hero learns the truth about the ancient origins of the Transformers. Joining the mission to protect humankind is Optimus Prime, who forms an alliance with international armies for a second epic battle.
- Q:I have just receive a gift from friends aboard. it is a transformer Universe Cyclonus with Nightstick. A Deluxe sized toy with Targetmaster partner.I have never heard about that. what is Transformer Universe? Is it a company similar as Takara Tomy?
- Transformers universe is a hasbro line Its not a company
- Q:How to tune to 14V? Why I tune the value of the above voltage meter has been always beating.
- 2, in the Proteus simulation diagram, double-click the transformer symbol, open the transformer parameter settings dialog box, which ??????????????? Primary Inductance 1H (set: can be fixed) ??????????????? Secondary Inductance 0.00406H (set by press)
- Q:Is the LTC transformer a regulated voltage transformer?
- If equipped with a load regulator is called on-load tap-changer If equipped with no load regulator is called no-load voltage regulator
- Q:How do I show the effects of putting a resistor in series with the primary of a transformer.Currently the transformer drops 120 to 6Putting the resistor on the 120 side what would happen? I am assuming it would drop the 120 down to some value which would then affect the secondary but I would like some numbers
- Transformer Resistor
- Q:Does anyone have any knowledge or experience with what happens if you try to run two different power supply transformers from the same AC line input. Can you do that? I have one transformer with a primary DC resistance of 28 ohms. I have a second transformer with a primary DC resistance of 265 ohms. I want to run these two transformers from the same AC power cord input. I tried connecting their primaries in series across the AC cord input, and the resulting secondary outputs from both transformers were lower than expected for a no-load condition. I am a little concerned about trying to connect the two transformer primaries in parallel.Any ideas?
- Connecting two or more transformer primaries in parallel is no different from plugging two or more electronic devices into the same outlet or power bar. Just be sure you understand what you are going to connect to the secondaries and how to construct your circuit properly.
- Q:440 kv(Primary side) and then at the receving station its step down from 440kv(primary side of the step down transformer) 33 kv.in the tranmission line,between both the primary side of the transformers the voltage is 440kv.then how the power flows in tranmission lines?
- A transformer can handle power flow in either direction. The primary may be either the LV or the HV side of the transformer, likewise the secondary. By convention the primary is the side where the power flow enters the transformer and the secondary is the side where it leaves. It is NOT that the HV side is always termed primary!! In this case the generating transformer (at the generator) has a 33kV primary and 440kV secondary. This is often called a step-up transformer. The power flows from the generator through the generator transformer and into the line. It then flows along the line to the second transformer at the receiving substation. Here the HV side is primary and the LV side secondary (in other words, as you mention, it is a step-down transformer). The power is flows through this transformer and out into the further circuits. The power is (substantially) preserved at each transformation by the transformed current levels being inversely proportional to the transformed voltage levels so that V x I constant. Although nominally the voltage at each end of the line is 440kV there may (or may not) be a small difference in the voltage magnitude and there will certainly be a phase difference. If the voltage magnitudes at each end are v1 and v2 respectively and the angle between v1 and v2 is A, then the power transmitted is (v1.v2 sinA)/X where X is the impedance of the intervening line
- Q:I am looking for a 220v transformer with these secondary voltages: 2x13v, 1x9v, 1x3vIt has to be at least 20va.I cant find this anywhere :/
- Unless okorder
- Q:Go transformers
- Between those two , Transformers.
