What else can I help you with?
Can you substitute 12V. AC 40va Transformer for 12V. AC 1000ma. Home service-out door fountain?
Yes, the output current of a 40va transformer at 12 volts is 3.33 amps. The replaced unit had an output of 1 amp making it a 12va transformer. By doing this exchange there will be three times the capacity of the new transformer over the old transformer.
What replaces a EM48-23B-N transformer?
I suppose it depends on what you are repairing, I just replaced this exact transformer in a vintage Mr. Christmas Carousel Calliope. It is a 6v center tap transformer, I replaced mine with the one below which can be found on Amazon and is a 1amp. My carousel works good as new. I hope this helps someone. Center-Tapped-Transformer-117VAC-12VAC/dp/B00SOY36M8
Can step down transformer be used as a step up transformer?
If the transformer has two separate windings, then, YES a step-down can be used as a step-up, and vice-versa.It is more correct to say you are reversing the high and low sides.By definition Primary is the "IN" side and Secondary is the "OUT" side.The Primary could be the high voltage side if it is a step-down,or it could be the low voltage side, if it is a step-up.Design ConsiderationsCare must be taken when reversing the operation of a step-down transformer to insure that it does not exceed the ratings of the transformer. For example, let's say we have a 12 VA step-down transformer that takes 120Vac in and is rated to provide 12V at 1 amp at the secondary. If we were to reverse it and apply 12Vac to the new primary (the old secondary), we would have 120Vac at the new secondary, but to keep within the original ratings it could only be loaded to 0.1A @ 120Vac.As long as you treat the output rating of the step-down transformer as the input rating as a step-up transformer, and don't try to draw current beyond what would normally have been applied to the high voltage primary, you should be fine. Potentially one could push up the voltage on such a transformer beyond what its stated application specified, while making sure not to exceed the power rating of the transformer and not exceeding the breakdown voltage of the transformer's insulation, for example driving the above transformer at 24V to get 0.05A @ 240Vac. It is important to realize though that the rated input voltage for a step-down transformer will likely not be a safe input voltage if you use it as a step-up transformer - for example, applying 120V to the above transformer with the windings reversed would generate 1.2KV!One important point to remember when reversing a three-phase transformer to a step-up is what kind of windings it has. Most three-phase transformers use a "delta" configuration on the primary side. This means that there are three "hot wires" and a ground, but not a neutral. (The white wire in a circuit). On the secondary side, transformers are usually wired up in a "Wye" (sometimes called a "star" configuration. Doing this allows the transformer to create a Neutral connection. If a step-down transformer is reversed to make it a step-up, the high (output) side will not have a Neutral connection. If one is not needed, say for a three-phase welding machine, this would not be a probem. However, if a Neutral IS needed ,say for lighting, reversing this transformer would not work. In this case, a listed step-up transformer will be needed. One final thing, if a step-down transformer is used as a step-up, a Neutral wire is not required to be connected to the input side.
What is zero pcb?
It's Basic Project Of Transmitter & Receiver circuit <<>> Poly-chlorinated-biphenyls, it is a oil used in transformers to dissipate the heat from the coils of the transformer to the transformer's case. This helps in the transformers cooling. The only problem, it was found out after many years of use that it is toxic to the environment. Zero PCB's is the terminology used for the new transformer oils that are not PCB based.
How do you install a thermostat downstairs when the original one is upstairs?
Snip the wires off close to the subbase so you`ll know which colors went where. Then snake the wire down to the new location and remount & wire it. In some cases it may be easier to run a new wire form the furnace in the basement up to the first floor rather than pull the existing one down from the second floor. Either way the procedure is the same. Just be sure if running a new wire that the new one has the same or more # of conductors in it.
What size are the speakers on the door of a 1997 Chevy cavalier z24?
4x6 ...On the new speakers the big wire connector is the positive (+) .....the left positive speaker wire is Tan.... The right Positive wire is Lt. Green
How do you replace battery cable?
You have to disconnect the ground wire from the block. You have to disconnect the positive wire from the starter and the alternator and the powerline going to the fuse box. and connect the new ground then the positive
What are the steps involved in doorbell transformer installation?
The steps involved in doorbell transformer installation are: Turn off the power to the doorbell circuit. Locate the existing transformer or install a new one near the electrical panel. Connect the transformer to the power source using electrical wiring. Connect the transformer to the doorbell system using low-voltage wiring. Test the doorbell to ensure it is working properly. Secure the transformer in place and restore power to the circuit.
How do you wire stereo speakers?
The new speakers come with un-stripped copper wires..... you need a pair of wire strippers.... i put in kenwood speakers and the size of the wire was 14 somethin. you would need to get a wire diagram for you car/truck to see the colors of the positive and negative wires. then look on the aftermarket speaker box to see which wire is negative and which one is positive.... After you would do all this, just match up negative to negative and positive to positive. simple as that. I'd recommend wire nutting the wires or electrical taping them... but DO NOT put all four wires together. that will mess your speakers' sound up completely. wire nut the positives together and then wire nut the negatives together.
How do you replace the positive battery cable in a 2001 Kia Sephia?
You have to remove the starter and run a new wire
Who dies in the new transformer movie?
The hot girl and the gun transformer =(
Replace the positive battery cable on a 2000 Pontiac Grand AM?
Disconnect both battery cables. Follow the positive cable on the 2000 Grand Am to the other end, looking at how it was routed. Remove the wire connection, and pull the wire out. Instill the new wire through the same routing, then reconnect the cables.
What else should you do if your AC fan will not stay on and you already have a new fan motor and cap?
Check to see that you are getting voltage to the motor. You must check for both high and low voltage. The low voltage for the fan usually comes from the green thermostat wire. Set your thermostat to the off position but the fan in the on position. Put your meter leads to the red thermostat wire and the common wire(usually blue) and you should get 24 volts. If you have no common wire use the red and yellow wire. This will establish that the transformer is working. If you get 24 volts the transformer is good, if you get no voltage reading the transformer is either bad or you have no high voltage getting to the unit. If your transformer is good check from red wire to the green wire, if you get 24 volts you have a bad tstat; if you get no voltage that indicates the tstat is good and the fan should be working, again check for high voltage. It could also be a bad fan relay.
What are car stereo wiring color codes for a 1999 subaru impreza I live in new zealand will this make any diffirence?
The 1999 Subaru stereo wiring color codes are universal. The red wire is the positive wire. The black wire is the ground wire. The green wire is the speaker wire. The white wire is the auxiliary wire.
Can be used current transformer as voltage transformer?
Yes Anyways You need thin copper wire, the thinner the more voltage output. Tear the secondary out of the transformer (The thicker wire) and save it for another project. Now wind the thinner wire where the thicker wire was and do it at about 1-2 volts added output per wind. Make sure you know where the two ends of the coil are and use the one end where the primary end is. Take the 2nd end of the new coil and put it on the other side. This is your output. <<>> No, a CT can not be used as a PT. They are two different types of transformers that are designed to do two specific operations in relation to voltage and amperage monitoring.
Why your Chevy Nova start to smoke near the starter after new battery was put in?
There is probably a positive wire touching a ground somewhere.
What are the steps involved in HVAC transformer replacement?
The steps involved in HVAC transformer replacement are: Turn off power to the HVAC system. Locate the transformer and disconnect the wires. Remove the old transformer from its mounting.
