1. Summary
SVC-D Series AC automatic voltage regulator is the latest product studied and produced by ourselves. These products adopt 8 digits CPU control produced by the well-known MOTOROLA company, which can stabilize the precision and set up the delay time. The products also have many protection functions on delay, over-voltage invert-delay, lack voltage, over load invert-delay, lack voltage, over load, over temperature, machine malfunction and so on. They have digital display, blue-screen lightproof, dynamic panel display and it can show the working status of the machine. When the machine works abnormally, on the panel there is corresponding due and short or long warning.

Q: actually we are trying to make a dc transformer,in which we want variable dc voltage at primary sidewe are doing this by using a rheostatwhich will change the value of current continously thus accordingly the value of voltage varyare we thinking right or wrong????: Once you have converted AC to low voltage DC you can use the volume control knob off a radio or amplifier to vary your DC voltage on the secondary side. You could use a ceiling fan adjuster or light dimmer to vary the AC voltage on the primary side.

Q: Hello everyoneI have a 110V hardware plugged in at home (we use 220V) by way of a step down transformer and I was wondering if transformers 'use' more power than usual. I don't want a nasty electircal bill.Because even when the hardware is 'off', the transformer itself is still on. It still hums. I am wondering if the transformer is constantly pulling power out of the wall socket 24/7 if I leave it on.Any help will be greatly appreciated. Thanks all.: There are 2 considerations here, they are called load losses and no-load losses. The load losses are directly related to the impedance of the transformer and the current flowing through the transformer. I would estimate that the load losses would be approximately 10% unless you have a really cheap transformer. That is simply the price you pay for transforming voltage. You will always have load losses. The transformer manufacturer can reduce these losses by using larger conductors inside the transformer. The second is called no-load losses and these are the losses that will occur even when no load is connected and no current is flowing. These losses can also not be avoided completely. However, you can build transformers to reduce no-load losses by using either more core-steel or higher grade core-steel. These losses are related to the magnetic fields generated inside the transformer. I can't predict the exact value of no-load losses but I would assume that it would normally be less than 5%, again assuming it is not made extremely poorly. So if you had a transformer rated at 500 watts, I would estimate that you would have less than 25 watts of no-load losses. So, as the person said in one of the other answers, I wouldn't worry about unplugging it every time I stopped using it, but I wouldn't leave it plugged in for days on end either.

Q: 80 kilowatts of electrical appliances need much transformer?: The selection of the transformer is based on the current. 80KW electrical current is 210A210 times (380 multiplied by 1.732) 138kva above the transformer can

Q: How many times does a copper wire have to go around the input side of a transformer to get the necessary amount of magnetism from 110 volts?How thick does the wire around the transformer have to be if the input it 110 volts? Can it be one wire as thin as a garbage bag tie, or does it need to be as thick as the original wire, but stripped and coiled around the transformer core?: The number of turns required is NErms/(1.414 pi f B Ac) where Erms is the primary RMS voltage, f is the frequency, B is the peak flux density which is a function of the material, and Ac is the cross sectional area of the core. The current density in the wire and the physical size of the transformer determine the temperature rise due to I^2 R (and core losses). It should be less than 400 amps/cm^2.

Q: I am looking for a transformer with an output of 6 volts, and 1.8 amps, or any transformer that can run that cycle. Please, let me know. I've been looking for months now, and cannot find anything. Please help. Where would I buy it? Lowes?: If you don't find it you have got to make it. This is a common transformer. Probably you are finding difficulty with it's current rating.

Q: does anybody know what Transformers 2: Revenge of the Fallen is going to be about? Like what is the whole plot, or storyline?: The battle for Earth has ended but the battle for the universe has just begun. After returning to Cybertron, Starscream assumes command of the Decepticons, and has decided to return to Earth with force. The Autobots believing that peace was possible finds out that Megatron's dead body has been stolen from the US Military by Skorpinox and revives him using his own spark. Now Megatron is back seeking revenge and with Starscream and more Decepticon reinforcements on the way, the Autobots with reinforcements of their own, may have more to deal with then meets the eye. I'd take that with a pinch of salt though as it's probably fan invented.

Q: Can dry transformers and distribution cabinets be placed in the same room?: Yes. Dry-type transformers are usually placed in the room with a shell, low-voltage cabinet is with the dry-type transformers together. The general practice is to flush the cabinet. And then connect the transformer with the low voltage cabinet directly in the cabinet to go. Outside can not see the connection of copper.

Q: I would like to attend a Transformers 2 Premiere where the cast will be present. Is that possible? Are these shows usually closed/private? Do I have to be in Hollywood? What should I do?: Transformers: okorder

Q: What is a transformer paused?: 3. If the user fails to apply for the resumption of electricity, the power supply enterprise shall, from the date of expiry date, calculate the basic electricity bill according to the capacity stipulated in the contract; 4. During the period of suspension, the user shall apply to the power supply enterprise five days before the scheduled restoration date when the user applies for the resumption of the suspension of electricity consumption. The suspension time is less than fifteen days, the suspension of the basic electricity charges during the period;
