Sony powerboard transformer PT902 1-450-043-11 secondary outputs

The transformer primary has been burnt out. I cannot get a replacement part from any vendor I have seen on the web. Can you tell me the secondary AC voltage outputs or identify a source of the original part.

SOURCE: JCR-160 clock radio Clock running slow

The clock works off the frequency (hertz). In US the electrical wave frequency is 60HZ/sec and in India and many other countries 50HZ/sec. Hence, the clock slows down about 6 seconds or so every minute.

You would need to rewind the coils.Do not try to do it by yourself if you have no idea what you are up-to...this time it was transformer next time it could it could be your circuit.Take it to a professional,the charges won't be much.
Good Luck.

Schematic malibu 8100-9120-01


http://waterheatertimer.org/Malibu-power-pack-stopped-working.html

I don't think they post schematic for the transformer
But generally, the primary coil receives 120Volt AC input from household electrical outlet
And the secondary coil produces 12Volt AC output for the low voltage lights.
The 'coil' is a coil of insulated wire wrapped around a metal core. Two coils set side by side create a transformer... when primary is energized, the secondary responds to the magnetic field caused by primary core... resulting in a current that flows on the secondary coil.
Output voltage on secondary coil is determined by the number of wraps and diameter of wire.

Some transformers offer a choice of secondary output... Kichler for example... you can select 12-13-14-15 Volt AC output
This is achieved by the way the secondary coil is wrapped.... for less voltage a wire is tapped at one point on the coil... for more voltage, a wire is tapped at another point on coil. This gives the user several wire choices to connect the lights.

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

To match it with an other transformer, you have to know about its secondary voltages. Try to download its service manual by internet. It will have all details. It will be best to contact any expereienced service technician or to the authorized service center for Nakamichi.

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.

Charger not charging,charging led not lite. Reading approx 3.2Vac out of terminals. On a good charger the reading is 4.8Vac Dewalt Charger ( Model DW9118) 7.2V-14.4V


You can try warranty services. However, if they are having an event in your area you might just try going down there. I have taken bad batteries to them in the past and they just GAVE me a new one.

My 36xbr800 blinks six times then pauses then blinks six times, this is repeated......


Check the voltage input to horizontal output transformer [LOT]. Check the voltage at the collector point of the line drive transistor. If the line drive transformer primary gets open this type of fault mau occur. Also check the frequency ant the collector point of line drive transistor and the base point of line output transistor. It should be aroung 15625 Hz.
Check and replace the horizontal output transistor if needy. Replacing it is better. The horizontal output is not working or a short in secondary power supply of SMPS or lot secondary, is your problem

WAVE radio transformer bad ???


If you can check ohms,you can also read volts. Open the radio again and look for DC volts on the rectifiers capacitors.They look like :cans", normally the color is blue. Check for positive dc v. against chassis ground. If no + tension,your rectifier or your secondary are open.

Transformer secondary out ???


please my name is dele i have this BOSE radio/cd system model number is AWRC2G which transformer burnt out rightly, that the input is 240volts which output is the problem and in nigria. please i just want to know the output on each coloured wire of the secondary that has 8 wires output from the secondary (2 purple - brn = volt, 2 blue = volts, and 2 black - gray = volts. so that similar that i can use to work it.
thank you

No control power


PRIMARY means INPUT(from supply side)
SECONDARY means output( to load side)
