1. Product Description:
Voltage stabilizer is a device which makes the output voltage stable. Regulator with constant voltage, control circuit, and servo motor, etc.. When the input voltage or load changes, the control circuit for sampling, comparison and amplification, then drive servo motor to rotate, and the pressure regulating carbon brush position change, by automatically adjust the number of turns of the coil, so as to maintain the stability of the output voltage.
The fixed output DC regulated power source is composed of isolation transformer, bridge rectifier,large capacity filter power tube of big power modular regulating circuit,protective circuit, it can work continuously for a long time with the function of sufficient output current,small wave,high stability,reliable performance,limited over-current protection and self-recovery.

4. Reference Picture:
- Q: even in a dc transformer, the cause varying current though not in polarity, can cause a change in the magnetic flux linked with a coil.
- Using a transformer with a varying DC signal was done all of the time with vacuum tube amps. Checkout the output transformer in the attached schematic and you will see its primary is being fed from high voltage(B+) DC. The output from the secondary is AC. Using a transformer is another way of blocking DC and passing the AC component of a signal. Note this doesn't mean that the DC is being pulsed on and off, rather it is varying with the applied signal. You can liken this to the algebraic sum of an AC signal with a DC bias voltage. 50VAC signal goes from +50 to - 50 volts Place that on a 100VDC and the result is a DC voltage that varies from 150V to 50V.
- Q: For most consumer electronics, there'll be a transformer within the adaptor that converts AC to DC. For the basic of the transformer, I'll just assume it's just a primary coil running the secondary coil.So, the primary coil keeps on running at full power, as long as electricity is needed for the appliances. Does this mean that even on standby mode, the adaptor still takes in full power from the power socket?
- Nobody has this exactly right, so here is what is happening: The transformer, with no load on the secondary presents a reactive impedance to the AC line which is fairly high. This is due to the inductance of the transformer. Any current flowing creates a magnetic field which induces a reverse voltage in the primary winding which in effect bucks the applied line voltage and limits current flow. Some energy is stored temporarily in the magnetic field during the positive half cycle of the applied line voltage, and then returned when the applied voltages reverses sign during the second half cycle. The net power consumption is fairly low, and is due to the resistance of the copper wire and magnetic hysteresis losses in the transformer's iron core. All of the above applies when there is no load on the secondary. When a load is applied to the secondary, the current flowing in the secondary circuit (which is also flowing in the secondary windings) creates a magnetic field which is in opposition to that produced by the primary winding. This decreases the EMF opposing current flow in the primary, so more current flows in the primary. Thus an applied load on the secondary presents a reflected load in the primary. Remove the secondary load and the reflected load disappears. So an unloaded transformer does not consume max power - but does consume a little power due to the copper and iron losses in the transformer.
- Q: I just saw the movie and it has left me with a thirst for more on the story of transformersbut where can I turnComics, animated series?Thanks
- Get the animated series. They totally rock!
- Q: The core part of the transformer is composed of sub-and sub-components, which are generally divided into two transformers. Urgent, quick answer What is the core part of the "what" and "what" sub-composition ah? The "What" son, this "what" is to fill you ah.
- The core part of the transformer is composed of (primary coil) and (secondary coil), generally divided into two types of step-up transformer and step-down transformer. (In fact, there is not a step up and not buck the isolation transformer) Did not hear the transformer "what son".
- Q: The difference between the reflection impedance of the ideal transformer and the hollow core transformer is different.
- The ideal transformer reflection impedance is the equivalent impedance of the load resistance equivalent to both ends of the primary coil, directly across the primary coil at both ends, in parallel with the primary circuit, and the nature of the reflection impedance and load impedance of the same nature.
- Q: I fried a transformer in my lathe. I went to the electrical supply near my house and the got me a new transformer and said it will work. The old transformer is 3 times bigger. they are both 100VA. the voltage on the original is 230v in and 100v out. It powers the on/off switches for the forward/ reverse micro switches. from the micro switch it powers the magnetic puill in for the contactors. The contactor say 100V.will using a 110v transformer cause and problems or issues?Should I return the one I purchased and order a 100V ?I have work piled up and waiting and really need this lathe operational ASAP.Thank You in advance for any information.Earle
- No, contactors and other electromechanical switches should be rated for at least twice the supply voltage, because of inductive voltage spikes during circuit opening.
- Q: A step-up transformer is connected to a generator that is delivering 131 V and 96 A. The ratio of the turns on the secondary to the turns on the primary is 859 to 1. What voltage is across the secondary? An-swer in units of kV.What current flows in the secondary? Answer in units of mA.
- Vp Voltage Primary Vs Voltage Secondary Np Number of Turns Primary etc The values you have given are primary, why? Because its Generator Transformer (GCSE stuff) Equation : Vp/Vs Np/Ns 131 / Vs 1 / 859 Vs 112529 V (large cause its a step UP transformer) 2). This equation is similar just slight different order: Vp / Vs Is / Ip (Hence you can rearrange this for power but not needed here) 131 / 112529 Is / 96 Is 0.11 A (2dp) Yet again you'd expect it to be small, because your transforming your voltage upwards to reduce your current (which of course creates less heat so less heat energy lost etc)
- Q: What are the transformer capacity?
- Transformer capacity has the following (unit kVA): 10 20 30 50 80 100 125 160 200 250 315 500 630 800 1000 1250 1600 2500 and so on
- Q: 1. a district 800 + a layer of 500mm2 shopping malls should choose how much capacity? 2. A 315kva transformer has been for a district 600 households electricity, ask there is a 70 households can access the transformer?
- In the actual choice, should adhere to the "small capacity, dense point" principle Distribution transformer location should be located in the load center, and the power supply radius of not more than 0.5 km. Distribution transformer load rate between 0.5 to 0.6 the highest efficiency, At this time the capacity of the transformer is called the economic capacity. But if the load is relatively stable, then the continuous production of the situation can be selected according to economic capacity transformer capacity.
- Q: Hi! Anything you wanna say about transformers, leave here!
- Transformers live action 2007 movie was defiantly more than meets the eye (especially since Peter Cullen came back as Optimus Prime!). I love Generation one more than the Unicron Trilogy.
