Q:i have plenty of 3 phase 220 in my shop, but one of my machines requires 440 3 phase. i was going to use a 75 kva transformer with 440 primary 220 secondary in reverse to supply the machine. it is a 15 hp motor 40 amps. i figured my minimum kva requirment to be 37.5 but more cant hurt for the potential high cutting rates i may need to achieve. i simply wanted to buy the transformer, hook the 220 3 phase supply to the primary, and the output to my machine. I think this will provide me with 440 output. the motor plate says 7-1/2 hp/15- hp. 40/20 amps. Any help is welcome, i hate to buy the transformer and not have this unit work. i would change the motor wiring, but the diagram is gone, and the wires are not numbered, also i believe id have to change all the heaters, which are hard to come by, as well as various other parts in the panel. just seems the transformer is the easiest way to get this machine up and going in prouction.: The only real problem you have to worry about is the capacity of the primary winding to supply enough current for your needs without burning up. That information should be on the transformer. Otherwise, transformers work both ways!

Q:I have a doorbell that quit working. I don't know how to tell if it is the bell or the transformer: Verdugo: go to the transformer and check for power coming out you should get a 24 volts dc. Then, check for power across the switch you should get the same, then check for power at the bell. If you have power at the transformer and not the switch then re-wire the system. The key is having power. If you have power at the switch and nothing happens when you press on the switch and you do have power at the door bell when you press the switch then the bell is bad. That simple. Just follow the circuit. and just comdem where it stops. you can also check for continuity at the switch. if you don't get any signal when you press on it. the switch is bad.

Q:I have a 25 volt 2 amp transformer from radioshack and a non push dimmer from walmart. The dimmer has two black wires and one green. The transformer has on one side two yellows and a black and on the other side two blacks. I need to know how to hook the dimmer up to an outlet then how to wire it to the transformer.: The number of wires on the transformer don't match with the stated voltages. The two blacks are probably the 120 volts input (assuming this is the US) but the 3 wires on the secondary imply you have a center-tap secondary, possibly 25 volts center tapped at 2 amps. I'm also assuming that the hot wire is sized to operate on 25 volts. The transformer should come with some sort of labels for the wires, if not take it back and get one that does. Once you get the transformer straightened out, here is a wiring list. AC hot from line cord black wire to one side of a 1 amp fuse holder AC neutral from line cord white wire to one of the line connections of the transformer AC ground from line cord green wire to transformer case and to case of dimmer (green) and to metal case this is all mounted in. Other side of fuse holder to one of black wires of dimmer Other black wire from dimmer to the second of the line connections of the transformer One of secondary wires on transformer to one side of the hot wire Other secondary wire on transformer to other side of the hot wire Tie the center tap of the secondary, if there is one, to ground. If not, tie one of the secondary wires to ground. You will note that I included a small 1 amp fuse. You can get a small metal box to mount this stuff in, or a electrical junction box. The latter is better as it has punchouts for cable in and out. Be sure to clamp the wires where they enter and leave the box.

Q:I have a bulb that currently uses a 120V primary to 6V secondary transformer. The load is a 30Watts. I would like to know what transformer I could use to power 8 bulbs (6v 30W each) ? Thanks. How can I calculate that?: Assuming you wire the bulbs in parallel. You need a similar transformer (6v secondary) but one that is rated at 240 watts (or a bit more), 40 amps. Note that the current will be 40 amps and will need quite a heavy wire, #4 or 5. You could also put the bulbs in series, and would need a 48 volt secondary, still at 240 watts. You would have problems of any series string, if one bulb goes out, they all go out. You can also use parallel series combos, 3 pairs, or 2 strings of 3 each as a compromise. edit. Later thought of another alternative that may help. Get a transformer with a 12vCT 240W secondary. Wire like you would 2 phase house wiring, 3 bulbs to each outside terminal, and all 6 to the CT. This means the wire only has to handle 20 amps and can be smaller, and you will not have the series string problem. 12VCT transformers are fairly common. Or if you can find it, and the wiring is still a problem, get a transformer with 2 secondaries each of 12VCT at 10 amps.

Q:I realize this may be super simple but i cant for the life of me figure out how to open a wall mount transformer it seems like they are snapped shut with no way to open?: They are glued, or even sonically welded. They are made to be replaced not repaired. They can be open by sawing a knotch in the corner and prying open with a screwdriver.

Q:I am a transformer factory salesman, the company let go to the field to run business, if you go to a strange city, where the main starting from where the few places, and which units to contact? If the local sales in the transformer factory, then work well to carry out? What are the sales channels?: 1. Power supply company tender 2. Cabinet manufacturers 3, the installation company 4, direct customers, to the planning bureau to find, in advance to know which new project 5, design institute, know some late 6. Power supply company front desk, people come to install more late

Q:Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts. Does the EMF (electromagnetic field) it generates pose any health threat to the household? Thanks-jj: This Site Might Help You. RE: is pole mounted transformer emf harmful? Hi, there is a utility pole in my lot and there is also a cylindrical shaped transformer hanging off of it. I did some research on it and it is used to step down the voltage from 7000 volts to 120 volts. Does the EMF (electromagnetic field) it generates pose any health threat to the household?

Q:Is the transformer a power supply?: Narrow power supply: refers to the other forms of energy can be converted into electrical energy devices, such as: generators, a variety of batteries; where the transformer does not belong to the power supply. Generalized power supply: refers to the ability to output electrical devices. It includes generators, various batteries; transformers; regulators; etc.; where transformers are power supplies.

Q:Hi,Should i wait for the Asus Transformer Pad Infinity, or should i buy the New iPad ?Thanks,Patrick: Hardware is negligible without software. The Google.play site (Formerly the Android Market) has plenty of apps to choose from. Basically, your investment is in the simplistic ease of the New iPad or the flexibility of Android 4.x. It's really a matter of which O/S you wish to support. I calculate the iPad IPS display has 25.7% more pixels than the new Asus model. Will you even notice the difference? Not at those screen sizes. Besides, the Asus has a 16:10 Ratio for a better movie experience. Personally, I have already seen that even the new iPad can't match wits with a Tegra 3 tablet when running certain games. Comes close, though. I'm waiting with baited breath for the Asus Transformer Pad Infinity. In my opinion, so should you.
