What is wattage rating of microwave oven transformer also hi voltage from secondary?
Fred36
The rating is about 1500W. This is for both the input and the output. Output voltage is usually 2,000 volts. Divide watts by input volts to get input current. And divide watts by output voltage to get output current. -Joe

Can resistors be used to use a 110 volts rated hairdryer in a 220 volt source?
Resistors could be used if you can find resistors with a high enough wattage rating to dissipate the heat that they will generate. Your best bet is to purchase a voltage adapter. The adapter is just a transformer that steps down the voltage from 220 to 110 volts. Locate on the hair dryer what the wattage draw is and then match the transformer (adaptor) to that wattage output.
To purchase a Transformer are given input voltage output voltage and wattage sufficient?
How much does it cost? Will it fit in the space provided? Is cooling for it provided? When can it be delivered? Does it need provision for tapping for minor voltage changes? Does it need provision for remote monitoring? Voltage variation with load. Conformance with applicable standards. Frequency. A TRANSFORMER IS A PASSIVE DEVICE SO YES THE INPUT VOLTAGE IS NECCESSARY FREQUENCY OF OPERATION THE KVA OUTPUT IS ALL THAT YOU NEED.
What step down transformer need to supply fluorescent lamp in watts?
To answer this question some values must be stated. The voltage and amperage must be known to find the wattage. W = A x V.
Is it dangerous to run an appliance with more watts than the transformer?
A transformer has a rating that is usually expressed in KVA. This is approximately a wattage rating. It is not dangerous but it can be the cause of some concern. An appliance has a set current that is draws. This current times the voltage is the appliance's wattage. The same goes for the transformer. It only has a certain capacity to supply a specific current that is governed by its KVA (watts). Driving the transformer beyond its rated capacity tends to heat the transformer beyond its working temperature. If left in this over current draw the transformer's windings insulation will break down and the windings will short circuit. This is usually the end of a working transformer. So short answer, more watts (amps) from appliance equals burned out transformer.
What does short circuit current available mean?
If you take a power source like a dc battery or AC transformer secondary winding and connect an ammeter directly across these power sources you can read the short circuit current available from that source. This gives a measure of internal resistance of the battery or the available wattage of the transformer.
What does a transformer in a microwave oven do?
It outputs high voltage so that the magnetron (which is recieving the 2000v the Microwave transformer produces) can emit microwaves and it will cook the food but if fed lower voltage it is like a lower wattage it will cook slower
How do you size a transformer based on amperage I have a 1 KVA single phase transformer I was told I can only put 4 amps across the secondary. This transformer is 240 volt primary 120 volt secondary?
On a 1kva you have 1000 watts capacity. To fine the current the formula is I = W/E. The secondary side of the transformer has the capacity of 1000/120 = 8.3 amps. In your question you do not put the amps across the secondary you draw amps from it. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. <<>> voltage times amps equals wattage
Why current in secondary coil in a step down transformer is higher?
A magnetic field is produced when there is a current in the primary coil of a transformer.^^^^basically magnectic fieldA changing current in the primary-winding of a transformer produces a changing magnetic flux in the core which results in a back-emf. in the primary winding through self induction, and a voltage in the secondary winding due to mutual induction.
What happens if transformer wattage is much less than load wattage?
If the load current is too high, the power lost in the transformer windings will be too high and it will overheat. If the voltage is excessive, the power lost in eddy currents in the magnetic core will be too high and it will overheat.

If increase load of secondary side of transformer. why primary side current increases?
The wattage must remain equal on the primary and secondary sides of a transformer. An example to the above statement with a 1000 watt step down transformer. To fine the watts (load) the formula is W = A x V. The primary side of the transformer has the capacity of 1000 W = 4.16 Amps x 240 Volts. The secondary side of the transformer has the capacity of 1000 W = 8.3 Amps x 120 Volts. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. As you can see the wattage (load) remains constant only the voltages and current change.
What is the wattage of microwave MW9113SS?
1450w
Can you plug in a 115 amp welder into a 110 volt outlet?
yes. 110,115,120,125 and even 130 volts are all in the same catagory. as power companies increased their output voltages through the years, 110 became 115, then 120, and so on. when buying light bulbs, look for the 130 volts on the bulbs data. not wattage, voltage. they will last far longer than 115,120 volts
Wattage needed for 750 milliampre?
That depends on the voltage V. Wattage P = amperage A times voltage V.
What is the wattage output of the Frigidaire FMV157GS microwave?
The wattage output of the Frigidaire FMV157GS 0.5 CuFt Over-The-Range Microwave Oven is 1,000 watts.
Is it possible to hook up a 110v appliance to a 480VAC?
I am going to say NO.... Although it would be possible if you purchase a transformer (with the correct wattage rating) to reduce the voltage from 480 to 120.
Why primary side of transformer blown?
It is either a short in (1 or more) of the windings (if its multi-phase) or the applied voltage was too high. What is the application, size (wattage), voltage, a number of phases for this Xfmr? I might be able to help you troubleshoot it further with this information.AnswerIt depends on what you mean by 'blown'! Do you mean the primary fuse has operated? If so, then it's likely the transformer's load has exceeded the capacity of the transformer.
