This is my first time to post on this particular forum. I have been searching for some specification on a transformer all over the internet when I happened upon this forum. I am not an electrical engineer, just a tinker that sometimes gets in over his head. I am attempting to make a DC power supply and I need a step down transformer that will provide me with about 16 volts at about 50 amps. I acquired a transformer that is purposed to meet those requirements but I have some doubts.
The markings of the transformer are as follows:.
Attached are several pictures. If my memory serves me correctly it looks like it came out of a UPS. I was instructed to apply volts to the yellow and white wires and then connect the blue and black wires together. That is supposed to yield He when on to tell me that I could get Or finally I could get Pretty versatile transformer if it can truly fulfill those claims and useful information as UPS transformer are easy to come by.
I tried to get information and googled every combination of the above listed numbers I could think of and kept coming up with UPS information but no one that was using this type transformer as a simple step down transformer. I'm not at all clear as to how a UPS transformer is wound. Some pages hinted that they are a bidirectional transformer that functions as either a step up or a step down transformer depending on the cycle the UPS unit is in.
Any assistance you all can provide will be greatly appreciated. Save me from the plug it in an hope method.
I have some doubts from looking at the pictures. What are the physical dimensions of the transformer? This is quite common to have a primary with a number of taps to allow adjustment of the output voltage.
Unfortunately as this appears to have come out of a UPS it is likely going to be difficult to find any data on it being likely a custom-made transformer. Do you know what UPS it came out of? A 50A output would need about 6-gauge wire. That might give a hint. The scale is hard to determine, but this transformer doesn't look that large. I have run into this problem before, electronic parts that are manufactured for a specific customer for use in their product and only marked with a unique part number.
A call to the manufacturer resulted in the comments 'manufactured for a specific job for a specific customer, no datasheets or specifications are available'. It's quite heavy, I would guess without actually weighing it to be around 15 pounds. The smaller leads are about 16 gauge and the other two leads coming out of the other side are about 12 gauge.
The inline fuse is rated at 15 amps.Best and cheap VA toroidal transformers is single phase, made with cold rolled silicon steel core and pure copper winding and lead. High Efficiency: Winding matches core perfectly, which makes the transformer more efficiency. Long Service Life: With high quality materials and manufacturing technology, the transformer can be used for 30 years. Less Noise: The core is seamlessly rolled and the winding is set evenly over it, which makes the transformer quiet when it is working.
Less Radiation: Toroidal structure and winding technology reduce electromagnetic radiation. With the advantages of small size, low noise, low heat generation and high conversion efficiency, the toroidal transformer has been widely used in areas such as industrial automation equipment, instruments, medical and health, as well as household appliances.
The toroidal transformer is mainly composed of coil and annular core, and the coil can be further divided into primary coil and secondary coil. Among them, some toroidal transformers have shielding layers between the primary and secondary windings, which are generally used in instruments and high-end audio equipment, so what is the function of shielding layer?

Shopping Categories.The control transformer is a kind of small dry-type transformer, which is often used as the power supply of local lighting, signal lamp or indicator lamp, and as the power supply of control circuit in electrical equipment.
Two points should be paid attention to when using the control transformer: One is the power of the transformer, the other is the correct wiring. The total power of the load connected to the secondary side shall not be greater than the power of the control transformer, and short circuit is not allowed. The primary and secondary wiring of the control transformer shall not be wrongly connected, especially the primary side wiring.
The voltage value of the primary side shall be marked on its terminal. It is not allowed to connect the V power line to the V terminal, but the V power line can be connected to the V terminal.
At this time, all the output voltage of the secondary side will be reduced by 1. The secondary side load shall be connected to the corresponding terminal according to its rated voltage, for example, the 6. My Account Register Log in Wishlist 0. Back Servo Motors. Back AC Servo Motors.

The voltage that the light fixture needs is the same as the voltage supplied from your wall. Low voltage lighting systems require lower voltage to operate than the typical power source supplies. So, if the power source in your wall outputs volts, low voltage lighting fixtures require an input of just 12 or 24 volts. That's why you need a low voltage transformer - to convert the voltage from your power source to the amount your lighting fixture needs!
Occasionally, the transformer is built right in to the lighting fixture - in which case there's no need for this guide. The decision has been made for you! However, if the transformer is separate, you'll need to make sure it is compatible with your lighting fixtures. Follow this guide to make your selection in four steps :. Low voltage lighting systems operate on either 12 or 24 volts. The easiest way to start filtering out the right transformer is to determine if the low voltage light fixture you need to power requires 12 or 24 volts.
Also, determine whether your power source outputs or volts. Most power sources in the U. There are a few pros and cons to consider here. Electronic transformers have an additional electronic device called an inverter that enables them to be much smaller than magnetic transformers. So, if you need to tuck the transformer into a tight space, you might want to veer toward an electronic transformer.
Another advantage to an electronic transformer is that it can be reset at the wall switch if there's an overload. Although magnetic transformers are somewhat larger and heavier, they are more durable than electronic transformers and they tend to last longer.
Now that you've determined whether you're looking for a volt magnetic transformer, volt electronic transformer, volt electronic transformer, or volt magnetic transformer that's a mouthful!
Each transformer has a "maximum wattage load. The rule here is that the maximum wattage load of your transformer must be equal to or larger than the total wattage of all the light fixtures you are connecting to it. Let's say you have one light fixture with one watt light bulb for the transformer mentioned above.
