SOURCE: tips how 2 wind transformer ac -dc

your windings of primary to secondary must be in a ratio of 20:1. That is, for a primary with say, 100 windings and input 240 VAC, 5 secondary windings will give you 12 VAC. you need to rectify then regulate if you want 12VDC. Just buy an off the shelf wall-wart.

How to make a transformer? What is the principle under it?


Do you mean an electrical transformer? You are far better off to buy one unless it is a special project. Constructing an efficient transformer is fiddly in the extreme.

The principle is that an alternating current (AC) voltage applied to a conductor will generate a fluctuating magnetic field around that conductor. The opposite also applies: a conductor in such a magnetic field will experience an AC current generated in it.

A transformer usually has 2 such conductors coiled around a common core, which intensifies and spreads the field. The voltage on the output side is controlled by the ratio of the 2 coiled conductors, or windings. So a transformer with 2000 windings on one side and 100 on the other has a ratio of 20:1. If a voltage of 240 VAC is applied to the first winding, a voltage of 12 VAC will appear on the other.

For calculation purposes the power is the same on both sides, so that lowering the AC voltage through a transformer implies raising the current at the same time, which can be handy. Therefore a transformer will often be rated by wattage, and input or output voltage. Note that a pure transformer will not work with or produce DC voltages, extra circuitry is required.

How to measure the voltage on TV


Voltage measured on DC scale, black cable multitester / avometer put on a negative path or can be slipped on the silver wire in the tube that is not disposable wrapping.

Next, measure the voltages are available:
  • For 180v voltage can be measured on the positive pin elco (10uf/250v) in PCB RGB tube.stick pin red wire multitester
d3f355a.jpg
  • Voltage 110v for TVs 14 "-21" and 130v for 25 "-29" in the B + FlyBack Transformer (FBT), find the path there is elco 100uf/160volt. measure on a positive foot elco.
  • For 12volt voltage, please measure at the foot of the right edge of IC 7812.
534aece.jpg
  1. For voltage 5V, please measure the right foot of IC 7805.
  2. For voltage 33v, please search at the foot of VT in tuner.
  3. To measure 90v-300v, scale use DCV 250.
  4. To measure the 12v-40v, use a scale of 50 DCV
  5. To measure the voltage of 1V-9v, 10 DCV-scale use.
  6. How to measure the voltage on the yoke and in plyback is;
    • From the yoke horizontal = Fcc 110v DC, 1000 V. AC voltage can be removed with a red plug in output and in use as dB meter.
    • From the yoke pertikal 24 DC current model, except for disposable coupling C = 1 / 2 Fcc. While it could be IC 120V AC (with dB meter)
    • At Fcc FBT kolector; 110v DC, AC voltage = 1000 V..
    • At Fcc FBT filement / heater = 5V-5, 5V AC.
    • In the FBT 20-32k anode voltage V measured with 40kv HV probe is added to the multitester 1000 V. DC.
    • Voltage others depending on model and type of TV. 180v out there (for RGB) directly from the regulators, transformers, Video Amp taken from FBT.
    • There are 24V and 46v vertical FBT, also 12-18V depending on brand and type.
    • Voltage 600 V DC and focus around the screen 400v DC.

    Thus tip n trick from me (AGUS YUSTIARA ), hopefully useful.

How to test your AC/DC Adapter or Computer Power Supply Unit.


A PSU or Power Supply Unit aka AC/DC adpater is then means by which a low tension (voltage) appliance receives its power from the 240 AV mains supply, the this is usually accompanied by the nominal current that is drawn from the PSU on load in milliamps. (e.g. 500mAmps = 0.5 Amps) most modern DC adapters are unregulated, where the output voltage is only regulated by the load current, and a smoothing Capacitor is sometimes used to reduce AC ripple on the DC Level.
If the PSU is regulated the DC Voltage that you measure using an AVO even off load will be the same as the rated current.

Also most, not all, are double insulated (indicated by small square inside a larger one) this means that it doesn't need a earth on the plug, the give away is a plastic pin instead of a metal one found in most domestic plugs with a 13A fuse.

Using Ohms Law P= I x V means that we can find out either the Current in Amps Power in Watts or the Voltage of any unit this is also called the VA rating

The Simple test is if the adapter gets really hot as soon as the you apply AC power then this may indicate catastrophic failure OR a dead short and you must turn OFF immediately the plastic may even start to melt, you may also smell electrical burning. This will also happen if you ever use a non-specific adapter on your device that has a different output voltage this will almost certianly cause damage to your device.

The main test if to test the step-down transformer using an AVO (Amps Volts Ohms) this is what is used to reduce the 240V ~AC voltage to something more in line with the required DC supply say 14-16V ~AC, a diode bridge converts this to DC, if it is regualted there will be either and either a zener or resistor drops this to the rated 12V and a capacitor to smooth the level.
You need to make sure this is socket is working correctly by checking with either a lamp electricians screw driver or a AC test plug, dont use this socket you have an earth fault or someother problem, usually two lines at the outside of a AC socket tester means all is correct.
  1. First measure the resistance (Ohms) across the two AC pins that is the Live and Neutral this should have VERY low resistance in the range 300 to 2,000 (2K) Ohms. if this is the case then your primary winding is probably OK if you see 1 on all settings this means open circuit (O/C)
  2. Then connect the power supply to a 240V AC socket, and check the output voltage with multimeter set at volts DC you should see a stable voltage of the rated value for a regulated adapter or slightly higher by about 5% if its unregulated as this is a reading off load, if you were able to test the voltage with the adapter on load you would see the rated DC voltage.
  3. If you connect an unregulated AC/DC adapter to the device and open up the cover to test it under load and the voltage is low around 5V or less then the adapter will need replacing even if the off load value appears correct in above test ( ** ref the table below)
NOTE: If you have a AC only output then the test done in 1 can also be done, if there is a diode bridge, Zener Dicde OR Capacitor on the secondary this test wont work so you might have to remove the cover by unscrewing the tamper-proof screws and test it before the connection to the PCB, without the power on of course, check out my tip HERE for help on how to remove the screws.

If you have a faulty power supply its usually the thermal fuse that blows on the secondary winding, this means that you will get considerably less Voltage at the output jack of around 5 VDC or less and falling if this is the case the transformer is faulty and will need to be replaced with one of the same step-down ratio. OR you will need a new AC/DC Adapter, check out this table for examples of the results that you might find.

f9329ce.jpg

** The Amstrad Black PSU that reports 24V and 383 Ohms on the primary may still not deliver the rated voltage under load and therefore I have marked this as a false positive and therefore FAULTY.

NOTE: The AC/DC Chargers are constant current devices (the symbol is usually two interlocking circles and even though you can do similar tests on the transformer primary coil its the current that it delivers under load that is important the only way to test this is using a clamp meter on the cable to see the current under load this should match the rated current.

COMPUTER ATX PSU

Most ATX power supplies are known as switched mode can only be tested under load when connected to the PC motherboard this is a bit tricky using a plain old Fluke, AVO or Multimeter the best way is to buy dedicated PSU tester for the type of Power Unit you have, it will check the DC voltages in the range + 12V,-12V,+5V,+5VBs and +3.3V on both the SATA and IDE supply cables these cost about £20 ($35) you can test the unit in as little as 5 mins.

After programming irritrol auto watering system I push the function switch to run and it turns the watering time to off so nothing happens. Voltage at the 24 volt terminal is 13.2 volts, however when


The typical lousy power source for this system is likely defective. They will normally rise to 140-150% of nominal voltage (24V) and settle around the required voltage when loaded.
Check the supply (if separate) for a rating of voltage and current; for example: "24VDC/XXMa" where the 'XX' is the current that will either be in milliamperes or amperes.
To correctly measure the voltage, you must know first if it's output is AC or DC.

If this is a DC supply, it probably has a failed diode, if AC, the transformer is bad.

A less likely, but possible problem, is that the programmer itself has an internal failure and is overloading the supply.

If you have a meter with a separate 10A jack, and you can interrupt either side of the supply line, try measuring the load current.
This will however, only be possible if the 10A can measure both AC and DC or if you know that the supply output is DC.

MY RCA 27" WILL NOT TURN ON, HAVE POWER TO THE FUSE, THE FUSE IS GOOD ALSO BUT THE DEGAUSS RELAY DOES NOT CLICK AND NO OTHER CLICKS ARE HEARD EITHER, WHAT COULD BE WRONG?


you need to check the voltage output of your power supply section.This power supply supply is a switching type power supply.there is a chopper transformer in there.its supply is a dc voltage unlike any other transformer which is AC supplied on the primary..First step.
1.Using a multitester measure the primary supply it is a DC voltage around 220v - 110 VDC
2.Measure the secondary output.The out put is AC voltage the supply for the B+ going to plyback is 115vdc the second output is 12v run through a regulator and the regulator lower the voltage to 5vdc.this 5vdc supplies the system IC and the jungle IC.this ic process the switching of the plyback transformer and the plyback transformers output supplies the voltage of the whole system including your relay in the degaussing section....once the plyback is activated the tv will now turn on...

good luck!Hope i helped you..

please rate my help..god bless!

Hi team I have 230volts at input pl32 but on switch on . Fault may have been a power surge .Thank you for any help Ray Styles ALSO badged Goodmans and Kenwood. pvr 160gB twin tuner hdd recorder


have you checked i f the rectifiers -diodes are stopping the minus part of the ac current,making it a dc voltage,ther either 4 single diodes or 1 round one which has 4 legs you want to measure the terminal marked with a plus sign i think,this should be a smooth dc voltage of half the input ac voltage ,in this case around 115 vdc.,it may been a power surge have you the mains suppressent capacitor,s this usually there to take the surge of 240 mains supply ,supplied by your energy company.during busy usage,there is usually a power surge ie,during tv ads,ets. is there any input /output current/voltage,to the dc transformer or out of it,have you followed the voltage/current throug the power supply circuit.

Powa Force drill charger is dead


Powaforce battery charger.

  1. Measure the dc output (with multimeter) on female plug. Should read ±16 – 20V DC. If no voltage here open charger and measure 220v AC on input wire before transformer. No voltage faulty input cable or 3pin plug. If ok check for dc voltage after transformer. If transformer faulty (not worth repairing) replace with same dc volts and amp (important)output. Check now output cable.
  2. If voltage is on cable but base does not light up, probable faulty capacitor. If light is on but does not charge, probable rectifier that gives too little amps.
  3. Any good tv repair technician can help you. My tv tech already fix about 9 of my torch and drill chargers. Parts usually about R5 – R10.
ps. email me the specs of your charger the input, output, the current (MA) and the voltage 14.v or 21v to globalsat1@gmail.com

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.

Use Sony ICF-C1IPMK2 in Europe


A transformer type (Linear Mode Power Supply) AC to DC power adapter with a 9.V nominal output, measures about 12.V without load when tested with a multimeter. A power adapter with a nominal output of 7.5 V, measures a little over 9.V. Considering a number of people across different forums reported the adapter's measured power output as 12.V, I think the nominal rating of the AC to DC adapter should be 9.V. However, keep away from Switch Mode Power Supplies.
