What is the rated output voltage for magnetron?


The magnetron outputs microwave energy. Do you mean the output voltage of the transformer? Many microwave oven transformers produce around 2KV at 0.5A

How to measure Voltage in Transforme for Fitness Treadmill


Transformer Test Procedure:1). Make sure that transformer wire connections (CON1) to the drive board are secured. Turn unit on.2). Put multimeter to the AC voltage setting. Insert meter probes into the transformer primary (red)wires as shown. Normal reading: 110V. This shows that there is power to the transformer.3). Test transformer output by probing on secondary (output) wires: black and black, white and white,orange and orange, yellow and yellow

Transformer Test Results :1). If there is no voltage across the primary (red) wires, inspect F1 fuse on the drive board and power to the drive board. 2). If there is voltage across primary wires but none across secondary wires, the transformer is bad.Replace it.

Transformer Wire Colors Normal Voltage Value:
Red and Red 110 VAC.
Black and Black 11-13 VAC
White and White 11-13 VAC
Orange and Orange 27-29 VAC
Yellow and Yellow 10-12 VAC

I need to replace the transformer inside my 12 volt charger. I can not find who makes the ES -66-287rev5 transformer. Need help.


If you have the skill to determine the transformer input is open, I would expect you have the skill to replace a transformer. Based on this assumption: determine the input voltage (120 vac?), determine the output voltage (14 vac?), determine the power requirements (output voltage times the charging current), find a transformer at www.digikey.com or www.mouser.com or www.newark.com.

There is a malfunction in the THT


Hi Hashim.
EHT (Extra High Tension) usually reefers to the 24kv to 30kv, focus and first anode (A1) voltages required to operate the crt (picture tube). These voltages are supplied by the line output stage, primarily the line output transformer (often refered to as the flyback transformer). This transformer steps the voltage up to 8kv and an embedded rectifier trippler circuit tripples this to 24kv dc to supply the final anode voltage to the tube (Hence the big rubber cap and thick cable.
The line output transformer is driven by a smaller transformer (line driver transformer) via the line output transistor.
The driver stage is fed by the hoizontal oscillator circuit.
So we can see that a failure in any part of this circuitry will most often result in no picture. The line output transformer is the heart of the system, it not only supplies the EHT voltage it also has to
supply an LT voltage for the vertical output stage but also the sound output stage.
A Fault in the A1 circuitry would result in a very dark picture but sound ok. Or the picture badly out of focus.
The line output transistor going short circuit results in no picture and no sound with the set shutting down to the standby mode or
hic upping (making a ticking noise. This problem would be amongst the most common and is easily confirmed with an Ohm meter. The line output transformer itself can develope an internal short with the same results (less common). Failure of the line oscillator and driver stages are most easily confirmed with an
oscilloscope. A fault in the power supply will also give these symptoms. To confirm line output stage is functional look to see if the tube heaters are glowing, this supply also comes from the line output transformer. Can you feel the static if you run the back of your hand across the front of the screen (often feels like running your hand through cobwebs. this would indicate that the EHT is present and the fault is elsewhere. Understanding how something
works enables you to find out why it doesn't. If you have occasion to replace a short circuit transistor, be sure to reslder all pin connections to the line driver transformer. I've found dry joints here
to be a cause for random inttermittent failure of this transistor,
Best regards from Vintie.

How to identify the matching transformer terminal by means of terminal resistance? and which terminals is for input or output?


Doing a resistance test on a transformer will not give the information you require as you will read very little, if any resistance. What you need to do is an impedance check and that gets involved. If it is a normally wound transformer, not an auto transformer, you can isolate which is the primary and the secondary windings. Unless the transformer is a multi voltage input unit, the primary side will have continuity through only two terminals. The secondary could be more than two if it is a multi output voltage one. If the transformer is a step down, the primary windings will be the thinner wired windings and vice-versa. To actually test the transformer, get hold of a transformer with about a 20 vac output and try it across the two terminals you have identified as the primary windings, you should ge a proportional voltage of the actual output. eg. with 20 vac input and a 2 vac reading at the secondary, the actual output would be 11 vac if your mains voltage is 110 volts. Take care that you are using the transformer at the voltage it is designed for, otherwise it will overheat and burn out.

How many parts in transformer & briefly explained


Firstly - DANGER.Power can kill so be very careful.
These can be made of a couple of parts but are sold as one peice.Check your manufacter for more info.

How Magnetic Iron Core Transformers work........
the transformer has a pair laminated wires normally copper or iron core wrapped around in a tight coil called windings.they are independant circuits not electrically connected together(x2 wires = 2 Circuits)
this creates a magnetic effect when power is applied to one end and mutual inductance creates a power output at the other end.Like a magnet really.

There are some transformers that have a multi voltage outputs called TAPS which will have different voltages to the input voltages.

ie
Input in New Zealand can be 230volts
Output can be 12 volts or 5 volts or 230volts
depending on the applications required,
for example

Street Transfomers can be 11,000 volts INPUT stepping down to 230volts.OUTPUT for your household power
or
Garden lighting transformers output can be 12volts but still be 230volts input
or
computers power packs can be multi voltage outputs of 12 volts,9 volts,5volts but still 230volts input.

There are also Electronic Transformers available too.
Commonly used for dichrioc Halogen downlights in homes or the office,

I have a HT-3000 Casio keyboard. I can't get any power when I turn it on. The power indicator light does not come on. Is this keyboard worth fixing? or can it be repaired at a reasonable cost.I am not...


Of course, don't try higher voltage. Something wrong with your transformer, it should be 9V as an output. Parts of component inside transformer have broken, such as resistors, capacitors or even IC. I'm affraid it cause your kboard power circuits have broken also.

NEW 600W L.V.TRANSFORMER DOES NOT PRODUCE ENOUGH POWER


This is more than likely what has happened . I am going to guess that your original low voltage trasformer was a 120 volt .6KW. Or 600watt transformer that has one lead from it to the lights . The newer less expensive transformer is also 600 watts , but the new one may have 2 sets of wire terminals on the back( 4 screws ). If this is the case , you have a transformer that is 600 watts output but it has 2 seperate 300 watt outputs that won't run 600 watts from 1 set of output screws . You will have to seperate the lighting load and may have to run an additional low voltage wire to half of your lights . In other words . Put 300 watts of light on 1 set of 12volt output screws and 300 watts on the other se of output screws .that will solve your issue . Good luck and enjoy your lights again . John
