1. Product Description:
Drive Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor power frequency mode to control AC motor power control equipment. Inverter is mainly composed of rectifier (AC inverter), filter, inverter (DC AC), brake unit, driving unit, detection unit, and so on. The inverter by the internal IGBT to adjust the output voltage and frequency, according to the actual needs of the motor to provide the power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are a lot of converter protection functions, such as over current, over voltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, frequency converter has been widely used.
2. Product Characteristic:
1 Frequency conversion energy saving. Motor use frequency converter is to speed, and reduce the starting current.
2 Power factor compensation energy saving. No power will not only increase the power loss and equipment of fever, more important is power factor lower leads to a decrease in power grid
3 Soft start energy saving. After the use of frequency conversion energy saving device, the use of inverter soft start function will enable the starting current from zero, the maximum value is not more than the rated current, reducing the impact on the grid and the power supply capacity of the requirements, and extend the service life of the valve. Save the maintenance cost of equipment

- Q: i dont get it. at the end of the movie. they did not kill one of the bad guys and he flew off to out of space?? do u think transformers 2 is gonna come out ???
- With or without Bay, they will make a Transformers 2. Actually there are a couple still alive. Barricade never showed up to the final fight. Starscream flew out into space. Maybe to go get more Decepticons. Plus who know what other Decepticons were already on Earth that just didn't show up to the fight.
- Q: How do you test this transformer with a multi-test meter? It was in a gong style door bell system. The 'clanger' unit has two windings withe the striker arm parallel to the end of the windings. Elaborate please. parts are difficult at my location.
- Watts are not equal to VA. VA equals volts times amps, just as do Watts. However, Watts measures power, meaning volts and amps are in phase with each other. Doorbells are inductive, and transformers are inductive, meaning the current (amps) and the volts may not be in phase. That's why it's convenient to rate transformers in VA, because the manufacturer cannot know what load is going to be applied. Generally, watts used in a system will be less than VA, because watts equals VA times the phase angle.
- 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.
- Mike, here is an easy approximation with no tech talk you can perform. Leave the power on to the transformer but remove the load and let temp stabilize. Feel how hot or better yet put a thermometer on the transformer. This heat is a direct result of transformer losses while idle. Next remove power to the transformer and devise a metal box to put a lamp in to heat the transformer overnight. Try to capture all of the lamp heat into the transformer to heat the core. Try this using various lamp wattages. When the temperature rise from the lamp equals the temperature rise from running the transformer idle the lamp wattage will be a close estimate of the power wasted by the transformer at idle. A wattmeter will also tell you this but they can be expensive. A good meter and an oscilloscope will be necessary otherwise but that is another story. Heat is always wasted energy the more produced the more it costs you to run. Regarding if you should let it run the answer is sure why not. You probably already have transformers running in your house all of the time. Door bell, Furnace, hot water tank, may be a few.
- Q: hi guys can any of you give me advice on wot i need 2do on removing and replacing a faulty line output transformer on a rear veiw projection tv as i have the part and the local tv shop wont fix it 4 me.wot would be the best way to discharge the power from it first and could i jus cut the 2 wires on the old 1 and use connector blocks to connect the new 1 in would this be ok to do or do it need to soilder connected on?. and is there any adjustments that would need to be done to the set when i have it installed be4 i turn it on any help much appreicated
- If you have an identical replacement transformer there shouldn't be a need to adjust anything to start. As to cutting wires to remove the old transformer to replace the new one, I suggest you make yourself a chart of any color coding of the wires or tagging them so there is no error as to what to connect to what on the new transformer. I personally would replace the transformer as the manufacturer installed the original one. As for discharging, use a 10K ohm resistor with one side to ground and the other side of the resistor to the components you want to discharge. I don't advise just grounding direct. Good luck and be careful.
- Q: Do you think if I asked this. which I am maybe people will pick Transformers because more Americans watch Trans instead of Gundam but if people watched both, would they still pick Transformers?
- What, in a battle or as in an anime? If it's anime, I pick Gundam. If it's a battle. Well Transformers got someone called Unicorn who's the size of a Planet. So you can imagine how powerful he is.
- Q: Transformer Uk = 4.5% What does it mean?
- Uk represents the transformer impedance voltage, refers to the transformer short-circuit impedance voltage. The impedance of the transformer (now the standard is called: "short-circuit impedance") standard value with a percentage (per unit value) to represent. General small distribution transformer standard value of 4% or 4.5%.
- Q: I was wondering which comic is the best read for an ongoing series about the the Transformers? It can be old or newMarvel, Dreamwave, or iDW. I was just curious because I have been a huge fan of the franchise since the first set of figures and generation 1 cartoon series but never read a single comic about them (which is actually very weird considering I am a huge comic geek) and just wanted to check one out.
- transformers are crap why do you read them?!?!?!?!?!?!
- Q: Hey!I Love Shia Labeouf I Was Wondering If Transformers Was A Good Movie I Haven't Ever Got A Chance 2 Watch It. Is It Worth Watching? These Are Some Of The Films I Like.Pirates Of The Caribbeanthe Dark KnightSpider man 3 Home Alones Mean GirlsThnxxP.S. I Heard Theres Going 2 Be A Transformers 2! D
- Transformers is one of my favorite movies. I loved it. It is action packed and Shia Labeauf is brilliant in it. You will love it. Transformers 2: Revenge of the Fallen will be out next year, so Rent Transformers!!!! It's out June 26, 2009!!!
- Q: I have a 34kv/380/500KVA transformer and it loads a pump of 450HP/2200V. Starting current reaches up to 1700 amps for around 3-4 seconds using a soft starter. The rated capacity of the transformer is 700amps and the pump running current is 689 amps.Any calculations to prove that the transformer is enough to provide the application would be a help.thanks.
- 500 kVA ÷ 0.380 kV ÷ √3 760 amps The nameplate rating (kVA) of a transformer is designed for 50% insulation life after being loaded to nameplate kVA and running with a top oil temperature of 110 °C for 20.55 years. (180,000 hours) Since your ambient temperature is not constant, and the equipment does not run continuously, the transformer's insulation will last far longer. In most real world applications, if a transformer is not loaded to nameplate, it will theoretically last for more than 100 years. Many electric utilities load their transformers beyond nameplate to take advantage of this overly long life. Motor Inrush: As for the motor starting inrush, the missing factor is how often the motor starts. If it is only seeing an inrush once an hour, the transformer can handle an inrush of 4x nameplate. Your motor's inrush of 1700 amps is 1700 ÷ 760 2.2 times nameplate. According to a transformer manufacturer's table, a transformer can handle an inrush of 2.2 times nameplate more than twenty times an hour. I highly doubt this 450 HP motor is starting and stopping every three minutes. You are good to go with the 500 kVA transformer.
- Q: I want to multiply current 10times for a second or two. So, is there any easy way to do that without using a high power transformer?Thanx.!
- Current from what kind of source, into what kind of load? Does the load take AC or DC?? What voltage does it need?? Why do you have to multiply the current? You can get clever with things like bucking switcher supplies to take 120 volts in and get 12 volts out at about 10x the current, but if your load isn't DC it doesn't help you. Edit:? 30 A @ 8 V isn't much, just 240 watts.? You can probably get this out of an old computer power supply; just re-wind (or add an extra winding in series with) the 5 volt winding on the toroid transformer to get 8 volts.? You may have to get fancy to get it to stay on (lots of the newer supplies want to be loaded, and want special signals to run) but with common supplies putting out 400 watts and more you should have no trouble.? The only issue is that you won't get 50 or 60 Hz, but since you didn't say your load has any particular frequency requirement I'll offer this as a possibility.
