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.

A primary and secondary usually refers to a transformer. The primary side being the input side 110 AC Volt or 220 Volt AC side. Also called Source.
The Secondary being the "output to load" side 12 Volts "for example". And also called Tap (Secondary Tap)

The voltage is changed by conduction, magnetic flux, neither side touching one another. And the number of turns of wire, per side, determine the voltage. The voltage may either be a step-down or Step-up depending on its use.
An unconventional method is to have both the primary & secondary combined into a single tapped winding - which arrangement is called an autotransformer. The autotransformer does not provide isolation between primary and secondary circuits but its simplicity makes it economical and space-saving.
Imagine a single wire wrapped from the top to the bottom being the primary, and tapping in. in the middle and bottom for the secondary, so the output becomes 1/2. That would be a step-down transformer.

The actual measurement of a transformer is measured by its efficiency (Faraday Law) which is defined as a ratio of power. I hope that's sufficient, but if you want more I would buy for $2 bucks an Electricity Made Simple Book, because there are pages after pages to write about transformers, and to understand electricity in general it is helpful to understand the difference between alternating current and direct current and its magnetic field of induction and magnitude of emf.

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

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.

I recently bought a U.S. version Nakamichi 600 II cassette console (120V), and I accidently burnt its transformer out by a 220V mains supply. Now I need to replace this burnt out transformer better with a...


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.

No power light on my hitachi modelcx-36w cd tape radio player but power to the machine the fuse is fine


If the radio has a power transformer check there is AC voltage to the primary "fuse side", [ 2 wires ] if yes check the secondary side, if no AC voltage is present the power transformer is open at the primary. The part must be replaced.

You had a direct short. One of the wires shouldn't have been where it was. Tell me the color of the wires and the hook up.

rule of thumb from thermostat
red to R
White to W
Green to G
Yellow or Blue to Y
no comm hook up from t-stat
now the control for the ac is the Y terminal
and the only wire left to Common. Generally speaking. Let me know the wire colors? ken

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

My sx-315 pioneer receiver overheated and shut down.


Probably the thermal fuse in the main power transformer. Check for ac on both the primary and secondary of the transformer. If you have 120v ac on the primary when the standby light is off and nothing on the secondary you need a new transformer.

I have a Pioneer SA_410 Amplifier. Has open circuit mains transformer. Could you advise what its AC secondary output voltage & current are? Regards


I have replaced many thermal fuses in power transformers. Is the primary open?? If so, cut the copper shield on the primary side of the transformer with a pair of cutters and peel back the paper insulation to reveal the thermal fuse. Replace it and everythings OK!! If the secondary is bad there's no hope, of course. Anyway, in the meantime I will research your question and post again very soon. I have several old pioneer schematics and know where to find what I need.
