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: How do I determine if a transformer is beyond the normal temp range and is at risk of failure?A 225 kva installed in 1996 is running hot. I removed the cover and using a digital thermal meter read approx 125 degrees F on each winding. 243 degrees F on the top metal (winding support) frame. It's got parallel 750's off the load side and would be an expensive and difficult change.: The temperatures you measured seem hot but might be acceptable for the type of materials used to insulate the coil inside the transformer. Only the designer of the transformer could tell if it's too hot or not. One rule of thumb : for non industrial electrical devices, the outside temperature of the device should remain at a temperature that lets you touch it without feeling pain. But one thing is sure: high temperature is not good because the transformer will age faster and it's less efficient (and therefore generates more heat). The transformer can overheat for 2 reasons : either your load is above the nominal rating or the transformer is not able to cool down as designed (usually because it's in an enclosure which doesn't let the heat get out). If you are indeed getting 750kva from it, then you are definitely at risk. That's more than 3 times the nominal rating. I would be surprised that it lasted for so long. If you can't reduce the load (best option), try to let more air flow freely around it by removing stuff around it. Last resort try cooling it down by forcing cool air to flow around it with a fan. But this can be tricky because the bottleneck of the heat exchange could be inside the transformer so the outside might get cooler and the inside could remain very hot.

Q: Transformer fever how to do?: ?National standard "dry-type transformers" GB6450-1986 on the dry-type transformer temperature limit to make the provisions. 1, the dry-type transformer coil, when the use of A-class insulation material, the ultimate operating temperature of 105 ℃, the maximum temperature rise should be less than 60 ℃; when the use of E-class insulation material, the limit operating temperature at 120 ℃ , The maximum temperature rise should be less than 75 ℃; when using B-class insulation material, the extreme working temperature at 130 ℃, the maximum temperature rise should be less than 80 ℃; when using F-class insulation material, the limit operating temperature at 155 ℃ , The maximum temperature rise should be less than 100 ℃; when the use of H-class insulation material, the limit operating temperature at 180 ℃, the maximum temperature rise should be less than 125 ℃; when using C-class insulation material, the extreme working temperature at 220 ℃ , The maximum temperature rise should be less than 150 ℃. ???The minimum temperature of the permissible transformer is the freezing point of the transformer oil, 10 # transformer oil, freezing point is not higher than -10 ℃; 25 # transformer oil, freezing point is not higher than -25 ℃; 45 # transformer oil, freezing point is not higher than -45 ℃ The ?????Transformer Equivalent Aging Principle

Q: If you have two 12 volt transformers and if we connect their hot wires together does the voltage become 24 or 12 volts? Please help, thanks so much!lt;3: If you connect them in series, you will get 24 volts. It's not a real good idea to connect them in parallel.

Q: I found out that rising the frequency of the power going to the primary will rise the output/ secondary voltage. So, if I feed a 60 hz 1:1 turn ratio transformer 100volts at 60 Hz (pure sine wave), the output will be 100 volts. but if I increase the frequency to 400 hz and keep the primary voltage at 100V, (pure sine wave) the output/secondary voltage will go above 100 volts. Or no?: this is yet in a diverse way. enable,Epvoltage around the popular winding; Es voltage around the secondary winding;Np # of turns interior the popular winding;Ns # of turns interior the secondary winding. Then, Ep (Es(Np))/N/s; (25(20))/one hundred500/one hundred 5V Step up transformer, or T turns ratio. T Ns / Np, one hundred/20 5v, Step up transformer. to your f.y.I in case you opt to parent a step down transformer,then, use the formula Es (Ep(Ns))/Np, or TNp/Ns desire this facilitates, persist with the electrical powered industry there's an incredible destiny and a few actual sturdy money to be made in it.

Q: As the title reads, Simply put: How did the original transformers series end? Aswell, how did some of the others, such as armada, energon, and cybertron end?: I don't know

Q: First of all, try not to be bias ;). My birthday is on December 19th, exactly the release date of the Transformer Prime, which is a great tablet, one I think surpasses even the iPad 2. With Steve Jobs gone and the new quad core installed in the Prime, would the iPad 3 be likely to be better than the Prime? Should I just wait for an iPad 3 if so? Thanks :)!: I think you mean the iPad 2 HD. The rumour is that it will just be a refresh first, then iPad 3 at the end of next year. But who knows iPhone 5 got released, right? ;)

Q: If I have a step down transformer, the voltage in the second coil decreases. From conservation of energy (Power of firstpower of second coil) the powers are equal. But if PU*I and the voltage decreases, does the second coil have a higher current in order to maintain its power?: A transformer makes use of Faraday's law and the ferromagnetic properties of an iron core to efficiently raise or lower AC voltages. It of course cannot increase power so that if the voltage is raised, the current is proportionally lowered and vice versa. hyperphysics.phy-astr.gsu.edu/hba Goodbye

Q: I thought the movie was great, but the death of Megatron seems really rushed and just unsatisfying? Agree?: Well there's going to be a second one and there has to be a villian, right? Wait for the new one! comes out on june 26

Q: Hi! Anything you wanna say about transformers, leave here!: Transformers live action 2007 movie was defiantly more than meets the eye (especially since Peter Cullen came back as Optimus Prime!). I love Generation one more than the Unicron Trilogy.

Q: Every yellow vehicle we pass on the road is BUMBLEBEE!!! and big trucks are opinus PWIME! And, he is constantly singing Twansfomahs, more dan meets dah eye! LOL So, I wanted to find him something for Easter that was transformers related, but as it's Easter, and NOT Christmas, I don't want to spend a lot of money. Suggestions?: Must his favorite cartoon thats just like my 5 year old nephew he is obsessed with Sponge Bob Square pants
