- Q: What is the difference between an ordinary power cable for a dedicated cable?
- Inverter special cable General power cable difference shielding requirements higher, the number of cores is generally 3 +. three lines of the ground line of three symmetrical and phase line intersection. Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on. The inverter will adjust the voltage and frequency of the output power by the breaking of the internal IGBT, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving, speed control, in addition, the inverter has a lot of protection , Such as overcurrent, overvoltage, overload protection and so on. With the continuous improvement of industrial automation, the inverter has also been a very wide range of applications.
- Q: my mac is fairly new, but is not charging. Are mac power cables this bad?..does anybody know if they need to be replaced often?
- Umm well we have had our Mac for about 9 months now and we have had to replace it once. So I think so, just like in iPod touches the headphone jack is screwed up.
- Q: The circle thing on the end of the amp power cable wont fit onto my battery, so idk what to do, should i strip the wire and connect it to my battery like that or should i cut the circle thing (i really dont know what the hell its called) to the point where it will fit around my battery
- I'm not quite sure how your trying to attach it to the battery, but you should be able to take the ring and slide it over the the little bolt that is on your terminal. After that just tighten the nut over it. If this isn't working you may want to invest in a aftermarket terminal. They're pretty cheap and depending on the one you get you should be able to hook it up with the ring on the end or strip it and connect it using whatever method the instructions say.
- Q: Our comcast HD cable box usually has the time and a little red light on front. Its blank and has no power. It is plugged into a power strip that also has the TV and stereo, yet those are working fine. We reset the power strip and still no power to the cable box.Any ideas? Please no rude remarks. Thanks.
- Cable boxes can die. I had two Comcast boxes, had an electrical storm and it knocked both of them out for good. Nothing else in the house failed. I called Comcast they sent out a tech with new boxes and that fixed it.
- Q: I do not have the Video Card in hand but I will in a few days and I already know the adapter cable has gone missing. The NVdia Website is no help. I have an HP Pavilion Elite desktop. I want to acquire the cable before I receive the Video Card, so I can install it right away. I want to know exactly the type of power connector cable is so I can go online and order it now.
- Power connector cable? Usually, you don't need an adapter cable: you just plug the video card into one of the PCI expansion card slots available on the motherboard, then you plug the monitor's cable to connect the monitor to the computer via the serial port on the video card. Knowing what computer you have doesn't really help: You have to tell us the motherboard's brand model to see if this particular video card is compatible for your computer's motherboard.
- Q: Which is the best way to prevent damage to the laptop / ac power jack when someone trips on the cable ?Dont ask me to buy a Mac since I already have one. This is for my new PC notebook.
- I would suggest using the velcro tye's you can get at any electronic store. Try tying off at the leg of your table. You can also use gaffing tape to tape it down to your floor. Gaffers tape usually doesn't leave a residue and is easily removed. Again, you can get it at Home Depot int he electronics section. Oh yeah, and be careful. :o)
- Q: I already looked at the company website and could not find the ordering option for those specific cords. HELP PLEASE!!
- each video demonstrate that i'm conscious of comes with a means twine and a VGA cable. despite if it rather is DVI in a position, then some comprise a DVI cable, others save a pair of greenbacks and don't. Ask once you purchase it.
- Q: I just finished building my shed, I put a 1 1/2 inch conduit under the shed coming up into the corner. I am now about to dig the 65 foot trench back to the house. I need to run power, not a problem. I want to run a phone line, a network cable, and a cable wire for my satellite. I say shed but it is 12 by 20 feet with an attic. Can I run these additional lines in with the power. I was thinking about using a run of Shielded cables for the network and one for the phone. For the cable some heavy duty quot;I don't know what thoughquot;. Will the power lines mess the data up on them? What will work for the three if any. If I need to I could run them in a new conduit, but that is not cheap!
- if you run you power line with any other line the phone company will take you out in the bush and shoot you. you must use two different conduit pipes.
- Q: Two things:1.) Why when we're using an AC to step up the voltage the power has to remain constant?2.) Why is it if we increase the voltage by a factor of 100 we have to decrease the current by a factor of a hundred and therefore I^2R is decreased by a factor of 10,000
- Power is generated at the power station and transferred to the end user your home by means of power cables. Unfortunately, some power is always lost in this transfer process. It's power NOT Voltage OR Current that is required to operate your home electrical appliance. Yes, current and voltages are involved ;but it is the PRODUCT of these two that makes up the power NOT the voltage or current individually. Power = Voltage x Current Power is lost in the cables as heat as given by your i^2R. To reduce the losses then we must reduce the current I. But, if I reduce the current and keep the voltage the same then the power will fall and my kettle/Xbox/curling tongs will no longer work at home. So, to keep the power up when reducing the current I must compensate by increasing the voltage and this means using a step up transformer. Near the homes, a step down transformer is used to reduce it back down again. Since the losses in a cable are a consequence of I^2R heating then it is important to reduce the current as much as possible when transferring power. If we assume the the resistance, R of the cable is constant, then a 10,000 reduction in power (power/10,000) gives P/10,000 = I^2 x R I^2 = Power/10, 000R I = square root of [const x 10,000] I = 100. Then using power = voltage x current reducing the current by 100 means increasing the voltage by 100 to keep the power the same.
- Q: I've looked on the internet, but it doesn't seem that the power cable for this printer is sold anywhere! Does anybody know if I'm able to buy it? And if so, where? I'm desperate. I don't want to buy a new printer. Even though this printer, actually, sucks. Let me know..........
- This Site Might Help You. RE: HP Deskjet F4280 - Power cable sold anywhere? I've looked on the internet, but it doesn't seem that the power cable for this printer is sold anywhere! Does anybody know if I'm able to buy it? And if so, where? I'm desperate. I don't want to buy a new printer. Even though this printer, actually, sucks. Let me know..........
