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.

Q:I'm building a ark welder and i know they get very hot, iv seen some people in ''the internet'' submerging their transformers in transmission fluid to keep em cool under excessively heavy work loads.My question is what effects does oil have on wire insulation?And what about the transformer varnish and core insulation wads and paper?: Transformers can be submerged in oil like the oil cooled transformers.The transformer varnish, cfore and paper can withstand transformer oil. Just use a clean transformer oil.

Q:I have 13 lights with 12 volts 35 Watts on each light for each tree, the outlet is 120 volts current now. Should I buy 300Watt or 600Watt low volts transformer to supply all lights? Need your advise!: you need to drop lights down to 25 watts ,and use the 300 , the 600 is just 2 300s not a solid 600. check out malibu lights web site.

Q:I have a transformer 12v and 12v need to reduce these further to be able to grow or shrink the rotational speed electromotor.Which device or component would be used to reduce the speed of electromotor?I making a mini escalators: A transformer has AC output, so first get DC, which needs a rectifier and capacitor. Following this is a voltage regulator using an LM317 (adjustable 3 terminal regulator). This can delivers ~1 amp. You should know what maximum current your motor draws under load. The first link is an example for 1.25V-15 V with an 18V transformer. Use a 12V transformer, and a 1000 ohm potentiometer as a variable resistor instead of 2000 ohms (R2). This will give voltages from 1.25V to 7.0V DC. Use the formula to calculate other resistors for a different voltage. Get the LM317 in a TO220 package, and you will need a heat sink, at least as big as in the picture. You can probably find a kit of parts for this in an electronics shop.

Q:Do you really think Transformer 2 is any better than Paul Zart Mall Cop? Not that Mall Cop was a good movie. Transformer 2 just went on and on, boring, boring.: Transformers 2 was better. The action was good and so was the story. Plus transformers has Megan Fox. Mall Cop wasn't that funny to be honest.

Q:If defects of one phase transformers can be improved by 3 phase transformer,then why not a 4 phase transformer used: If you use more than three the phase angle between phases will be different. Between phase 1 and 3 the voltage will be double where as between phase 1 and 2 cosine 45 of the phase voltage. So it will be very confusing to correctly connect phases.

Q:Transformer how to do no load test: Transformer no - load test 1, the transformer no-load test power capacity of choice: To ensure that the power waveform distortion does not exceed 5%, the test sample of the no-load capacity should be 50% of the power capacity; the use of pressure from the pressure, no-load capacity should be less than 50% of the regulator capacity; The no-load capacity should be less than 25% of the generator capacity. 2, no-load test is to measure the rated voltage under no-load loss and no-load current, test high side of the open side, low side pressure, the test voltage is low voltage side of the rated voltage, test voltage is low, the test current is rated current percentage A few or a few thousandths.

Q:i have been looking at transformers and i wanted to know a few things. will they do dc current? do they just add x amount of volts or do they multiply by x or just change to x? also there is a sort of container that goes around them is that carbon???? it goes all the way around and then through: Transformers only operate on AC current because they use a phenomenon known as electromagnetic induction, which requires a changing magnetic field. They multiply the input voltage by a constant value which depends on the ratio of the number of coils in the input and output circuits.

Q:After the calculation, due to the different cooling, the current density is different, I finished a winding section 96.5mm ?, secondary winding section 1562.5mm ? What are the specifications of the copper row? Another request for a transformer copper specifications table.: Answer: no love language, all the text is boring.

Q:What is the transformer through the full and half through the problem, the definition of a little more, the best reference, or sent to my literature.: Dual split transformer compared with the general power transformer, there are four important impedance parameters: (1) through the impedance: two low-voltage winding in parallel, the high and low voltage winding short-circuit impedance, that is, high-voltage winding short circuit, two low-voltage winding in parallel after adding the current equivalent impedance. Where the reactance component is referred to as crossing the reactance. (2) half-crossing impedance: one of the two low-voltage windings open, the other low-voltage winding between the high-voltage winding short-circuit impedance, that is, high-voltage winding short circuit, a low-voltage winding open, and the other does not open the low-voltage winding power Value impedance. Where the reactance component is called a half-pass reactance.

Q:If on the secondary coil we tapped the center to ground, why is it that the top to middle is opposite in polarity when compared to the middle to bottom of the inductor? Also does this only happen if their is a change in current and not constant current going through the transformer?: the first question think of it as a single coil, 24 V transformer when you measure from bottom wire to the top wire you will measure 24V if you measure from bottom to center it will be 12 V the same from the center to the top maybe it is easier to understand if it were 2 batteries in series images.google.ca/images?hlfrsou at the moment in time that the top is +12, the bottom is -12 therefore giving the 24V this is always like that regardless of the nature of the load Anita
