Product Description:

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.

 

2. Product Characteristic:

It is available for any places that requires DC power supply as laboratory,industrial control,telecommunication,electrical maintenance,accumulator charging,electrolysis and electroplating, etc。

Q:What is an electrical transformer, and how does it work?
I know this isn't what you asked for, but it gives a much better answer than I'm willing to type.
Q:How to use transformer 10 in DC circuit
DC-DC converter can be used, its working principle is: the input DC voltage through the oscillator into high-frequency AC, and then by the high-frequency transformer boost, and then rectification to get the required DC voltage.
Q:Flyback Transformer Questions?
The flyback transformers used in TV's work at about 15000 hertz (the horizontal scan frequency). The transformers used in switching power supplies are smaller and work at a higher frequency, but they normally have a low voltage output. The transformer produces a high AC voltage, and a rectifier diode changes it to DC. Reversing the diode gives you a negative output. The picture tube provides capacitance to smooth out the voltage and holds the voltage for a while after the power is turned off. If you don't use a picture tube, you might need a capacitor if you want a steady output voltage. Shorting out the capacitor will remove the voltage.
Q:Transformers manga?
I don't know but that'd be sweet!
Q:What should I name my Transformers series?
Huge transformers fan? you got me ;D Sounds pretty cool. can I read it when youre done? The Ultimate Alliance Rise of Unicron it would be great if you could add more details so I could think of more names : just give a rough outline perhaps?
Q:Transformer Coupled Amplifiers?!?
1) Its basically impedance matching: the relatively high output impedance of the first stage can be matched to the much lower Hie input impedance of the second stage. Also any attenuation caused by the shunt resistance of the bias resistors working against the output impedance of the first stage (as shown in the R-C C coupled figure for question 2) can be eliminated by applying the bias network voltage at the low side of the transformer secondary, with that point bypassed with a capacitor to provide a good ac ground 2) Replace the 4K collector resistor with the transformer primary winding, eliminate the capacitor C3, connect the high side of the secondary directly to the base of Q2, connect the junction of R1 R2 to the low side of the secondary and add a capacitor from that point to ground to provide adequate low impedance at the lowest frequency of interest. Transformer coupling is efficient, but bandwidth is limited by the transformer, and the overall gain will vary with individual transistors. Both of these warts can be improved by applying negative feedback from the output back to the input stage.
Q:What happens when power transformer used past amperage?
Try it and find out.
Q:Asus transformer and asus transformer prime?
Yes the transformer is different and older than the transformer prime. It has NVIDIA Tegra 2 processor vs the tegra 3 in the prime. Tegra 3 is a quad core 1.3 ghz processor and the tegra 2 is a 1ghz dual core. You should definitely get the prime but dont buy it yet. ASUS sold out the first batch which had a few issues, and they are releasing the bugs fixed second batch soon with Android 4.0 Ice Cream Sandwich pre installed (I could be wrong here), so wait till then and buy it with the keyboard dock which doubles the battery! I'm waiting for the prime to come out soon too! It is very thin and thinner than the galaxy if not the same. Hope this helped.
Q:Transformers and Efficiency?
Q1. Let the number of primary turns Np; number of secondary turns Ns. Let the primary voltage Vp; secondary voltage Vs. Then fundamental transformer theory gives us: Vp/Vs Np/Ns. So: Ns (Vs/Vp).Np i.e.: Ns (220 / 11,000).3200 64. The turns ratio is 50:1 Q2. The product of volts and amps is called the V-A of the transformer: volts x amps. An ideal transformer would generate zero losses in transferring electrical energy from primary winding to the secondary winding. But there is no such thing as an ideal transformer: the transference of energy means that some energy gets lost: in heat, eddy currents and hysteresis losses. For this Q, the input VA 220 x 3 660 V-A, and the output V-A 110 x 5.6 616 V-A. The V-A efficiency (V-A out) ÷ (V-A in) 616 / 660 0.933 93.3 % N.B. This is not the same as the watts efficiency, power in ÷ power out: the V-A efficiency does not take power factor into consideration.
Q:why the low voltage winding is wound at first in a 3 phase core type transformer?
The low voltage winding is placed closer to the core because the high voltage winding requires more space due to its MV insulation. If designers put the LV winding outside the MV winding, the tank would be larger because the _MV_ winding size would be about the same size. More insulating oil would be required, and the leakage reactance would be significantly higher. Remember, higher leakage reactance means that the voltage regulation (more aptly voltage drop) under load will be higher, which is not desirable. And, of course, a larger tank and more oil make for a more expensive transformer. Edit: MV winding is about the same size for either configuration, due mainly to insulation requirements.
