Schematic diagram example of AC DC regulated power supply 1.5volt to 35volt


You will need to add transformer and rectifier diodes before this circuit to be able to get the voltage you need.


See the link below of the regulated part of the circuit

Wiring diagram for Thermoking V700MAX


Red or R is the "Hot leg" of the Transformers 24volt supply,
Common or C is the "Neutral leg" of the Transformers 24 volt supply;
and the side of power to which ALL the 24 volt control circuits
terminate to complete the circuit, example; Heat=W, Cool=Y, Fan=G.
Upon a call for heat a switch closes betwen the Red and White Thermostat terminals.
The stat sends the 24 volts to White or W for the heat circuit on W on the
furnaces LVTB low voltage terminal board.
Yellow or Y goes from Thermostat to furnace Y on LVTB, which is simply
a connecting point on its way to the AC units 24v contactor coil located outdoors.
It actually isnt even attached to the furnace many times as it serves no purpose there and simply
continues to the AC unit with the copper lineset that the AC unit feeds.
The remaing 24 volt Thermostat wire goes back to common on transformer to complete the Yellow
24 volt control circuit.
Green or G exits the Thermostat and connects to G on LVTB for the fan relays 24volt coil
and returns to Common to complete the Green 24 volt control circuit.
O is for a Heat pump reversing valves 24 volt solenoid, and return to Common as all 24v circuits must to terminate or complete the circuit.
Some parasitic type Termostats need the 24v power to run, some are battery, some are both.

I have an electra split unit a/c. A red light is on with a sign like an S with two lines. What does it mean? thanks


look around the circuit board or on the board or diagram it will tell you the trouble codes for the light flashes

Circuit diagram


I'm afraid I cannot comply with your wishes, as there are copyright laws governing this, for one. (For existing circuitry)

Two, there is the liability issue. Take for example that I design the requested circuit, give it to you freely, and you or someone in your group is injured using my circuit.

Will state that this is a basic circuit design. I believe that if you 5 put your minds together, you can build this circuit.

Burn out circuit board


hi! there! replace the burn out circiut board,what ever you pull out the same thing you put back just be sure that has the same model and specification,calibrate and test overload protection,defective overload protection replaced to prevent any burn out,short circuited mostly came to burn those thing that's why imposing preventive maintenace schedule for this kind of large ac central unit is very much significant.mostly timer delay circuit malfunction on large scale unit supplying by three phase a/c source on central control panel board.when ever replacement occured try to put mark or list color coding of specific terminals to connect and isolate short circuit make possible to detect at once before installing the new one and make make record on this for future reference we have several cases like that after buying a new one and replaced still burn again,the common cases is that they did not find the cause of short circuit connection they just relay on circuit board burn out,so it better to make assured that every thing is fine before installing the new one.specially on supply source of circuit.,relay on diagram and manuals take and check all data source as reference this will be a great help.take all necessary precaution this should be done by qualified technical ac support,have a nice day and regards

Fan will not shut off, but compressor does


hi! there, continous fan motor when unit was shutt off,since supply source was already cut off specially on fan condenser motor,the supply of your motor was came from relay mounted on your circuit board control panel,there a holding coil to hold the connection between your fan and ac source,shut off breaker for ac unit first before diagnosing ac unit, try to check this out the relay is still activated giving ac source when shut off,the contactor on relay holding your ac supply was shorted,try to check the connection the circuit activating condenser fan relay,eliminate the short circuit,using multi tester test rod,use manual diagram for circuit control board to lessen complicated diagnosing,focus on fan relay ac source then isolate checking the short circuit replace defective relay,contact point of relay are not repairable.take necessary precaution on checking to avoid shock,this a hard task i would suggest that certified ac technician w/ full knowledge of instrumentation should do this.thank's for selecting fixya and have a nice day.

Xerox Phaser fault 37,002,47:18505


37,0XX.xx Errors - PEST Faults
AC power supplied by power sources such as uninterruptible power supplies
(UPSs) or DC-to-AC inverter systems may not supply correct voltage to
properly power up the printer. Likewise, other devices sharing the same AC
circuit can cause AC voltage sags that cause the printer to fail its AC heater
PEST tests (Print Engine Self Test). The printer may produce any of the
following disconnected heater errors:
■ Printhead jet-stack 37,002.47 or 37,003.48

Error Messages and Codes
■ Reservoir heater, 37,004.40 or 37,005.41
■ Drum heater error 37,006.42
■ Preheater error 37,008.44
■ Ink melters errors 37,009.45 thru 37,013.40
The printer includes several heaters powered by AC. The printer itself can
power up despite insufficient or irregular AC voltage but it may fail its AC
heater tests. This is due the test not measuring sufficient current flowing
through the heater at the moment the test runs.
Devices sharing the printer’s AC circuit shared, such as a laser printer, a
coffee maker, or a space heater, may be placing heavy intermittent demand
on the AC circuit. This sudden inductive demand creates momentary AC
voltage sag that causes the PEST test to fail.
Verify the AC power source prior to troubleshooting these errors. For wiring
diagrams to aid in diagnosing PEST faults, see “Wiring Diagrams” on
page 10-1.
8400/8500/8550/8560 PEST Description
37,001.46: Generic PEST error.
Something went wrong during the PEST process.
37,002.47: PEST Error - Printhead Left jetstack disconnect. The left jetstack is
not drawing the expected power from the supply.
