JDXF-35 Voltage Transformer Outline Drawing
Srructure drawing
- Q: Hello everyoneMy last question may be a little misleading and I couldn't respond to my own question so please forgive me when I rephrase it again.I have a 65w stepdown Input230/240 AC, Out: 115V AC. 65VA transformer and I wanted to know if I should be concerned about how much electricity the transformer draws just by the fact that it is plugged into the wall socket even when the hardware connected to it is not on.I don't need an exact figure. Just a layman's terms as what your typical transformer would draw. An absolute average idea of the average transformer.If I turn the transformer off, all my appliances will need to be reset when I turn the transformer back on again.So does an average one consume as much as a light bulb, or say something much more. like a computer etc.I just need a general idea. Thank you.
- No-load losses are primarily due to the so-called iron losses, i.e, hysterisis and eddy-current losses, and to a smaller extent, I-square-R losses. They vary quite a bit, but you can use a ballpark estimate of 5% to 15% of your transformer rating. Estimate between 5W to 10W of losses for your 65W transformer.
- Q: I really want a better transformers than 4 1 was great 2 was crap 3 good 4 worst of them all
- Yes, there will be a Transformers 5. When we don't know. Many people are thinking 2016 or 2017, but i have a friend that works in the movie theater and she knows the next movies for the next 2 years and Transformers 5 was not on the list. Is that because Transformers 5 has no name yet? Maybe. So Im assuming its coming out in 2017 or 2018. As for Paramount pictures they are not even thinking about Transformers 5 yet. As they stated once its one movie at a time.
- Q: The book said the main transformer power failure operation should first stop the load side after the power side, is to prevent the transformer in the case of multi-power reverse charging. What is the transformer anti-charging here? What's wrong?
- Here to step-down transformer as an example: The forward power supply is powered by the high side of the transformer to the low side of the transformer, and the "reverse charge" is powered by the low voltage side of the transformer to the high side. When the main transformer power failure operation, we must first load side, that is, first stop low side, after the power side, that is, after the high pressure side; If there are two main transformer running side by side (or other means of multiple power), when one of the main transformer power failure, if the first stop high-voltage switch, then low-voltage switch has not been disconnected, will make another master Variable power through the low-voltage switch back to the transformer power supply, resulting in transformer back-off situation; this situation not only failed to power transformer, but also increased the impact of a transformer, when there is over-voltage, etc., may cause resonance hazards Equipment safety.
- Q: I have a 240v-5v transformer for recharging, and it makes an annoying very high-pitched squeaking noise. What causes the noise?
- SQUEEK? That sounds like a high (audio) frequency oscillator. So this sounds like a pulsed regulator, not like a transformer-type power supply. I would guess that your unit is measuring the battery voltage, then applying a pulse of power to charge the battery, then checking the voltage again in a continuous sequence. This would be a switching type charger. 5 Volts - sounds like a personal electronics unit, for instance a cell phone or personal entertainment. Right? 240 Volts - Sounds like Europe. Right? (In America it would either be 120 Volts or some switching supplies are designed to operate from 90 to 250 Volts.)
- Q: I have been reading about pulse transformers and i am curious if there exists a pulse transformer that would take 1 pulse/second or even less and convert to very low voltage high current. If not, would it be possible to make one? Any info is very appreciated! Thx!
- Pulse transformers can be wound to any turns ratio that is desired. That being said pulse transformers have small cores and therefore handle small amounts of power. You can find cores on those old mother boards that are no longer in service and junk computer power supplies also have a couple of cores. These toroids were normally used as filter inductors to remove spikes from DC or low frequency lines. You can easily rewind them for pulse transformers.
- 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: I really want to know what a transformer is, how it works, and why it works. I really want an answer that goes down the the atomic scale. I really want analogies. And please don't copy and paste stuff from websites. Please don't worry about getting second comment. The most scientific and well explained answer gets best answer.
- I know this isn't what you asked for, but it gives a much better answer than I'm willing to type.
- Q: Can a transformer alone be used for amplifying audio signals ? If yes how ?
- Transformers are AC (alternate current) devices and if 60 Hz is supplied to the primary windings 60 Hz will be produced at the secondary terminal. The transformers transform voltage and current at the primary to voltage and current at the secondary by magnetizing a mass of iron in their cores. The magnetic cores may not respond efficiently to very high frequencies (transmission frequencies) but might respond to audio frequencies (loud speakers employ magnets and coils of wire). If a suitable audio signal was applied to the primary coil a transformer might be used to step up or step down the voltage of the supplied signal while reversing its phase, however power (P EI) would remain nearly constant.
- Q: Will the 250KVA, 500KVA, 630KVA Van transformer size,
- Box transformer inside the configuration is not the same, the size will be different, which factory production size is not the same
- Q: I was very disappointed with Transformers 2, there was no acting way too much action. Does anyone else feel the same way?
- For what it was, i think it was a good movie. It wasnt meant to be competing with strong movies with a powerful story. Just action entertainment. You need to put it in perspective with what it was meant to be.
