Dear all, can anyone help me for 200-240 volt AC out stabilizer which can operate from minimum 140 volt input using 2 relay and without chattering the relay also transformer use his own LT i.e. no additional transformer for relay operation. please arrange for transformer taping relay connection and circuit diagram. i will be highly obliged.
It can Stabilize Mains voltage to around +/- 10% . It can be used for both 110V AC or 220V AC inputs with modifications. The Output is 220V AC. There is an overload, under voltage and over voltage trip circuit.
hi we've designed a stabilizer for industrial purposes. the design details are these: the output voltage is 220V 50Hz. a microcontroller generates a sine wave. the sine wave applied to an op-amp amplifier and then a push pull amplifier. there is a feedback from the output of push pull to the input of the op-amp. the output of the push pull is co
I've been looking for transformer-less AC-AC converter. How these converters works, what is the working mechanism and everything. I found a voltage stabilizer that is working very fine, that circuit is using just a big inductor and few FETs. I still don't know what is the technology behind this. Need help. Thank i
Hello i need Static Voltage stabilizer circuit/documentation to make minimum 1kva stabilizer which could operate from 160v
What does the LED do ? Try attached .hex file. Vary voltage and see if the Relays turn ON/OFF at required voltages. LED is not coded. Explain when the LED has to turn ON or OFF. Test without connecting load to stabilizer. Mention at what voltages the relays are toggling with my .hex file.
a/c voltage stabilizer circuit 100v-260v input and 220 output
Hi everybody, I want help. I founded a 16f676 based voltage stabilizer circuit. but I cant find hex file for this pic. Can any one give me hex file I am saying upload photo of solder side of pcb(if you can not draw schematic). @srenjis Provide the circuit. i got this circuit from same forum.

Dear friends , I m working on a project : zero voltage switching ...relay based stabilizer..... Please suggest any design challenges faced.... So far i have to sense the ac mains voltage ...and based on the voltage , i have to switch the tapping of autotransformer through relay.. Now i am planning to use the zvc optocoupler like moc3061 fo
Dear experts, can we use dual operational amplifier IC ( like LM358 ) in 2 relay staiblizer instead of ( LM324 ) a quad operational amplifier. if we can please send me circuit diagram schemetic. with transformer volt tap. i will be highly obliged.
Dear all, here is i am attaching here 2 circuits for AC staiblizer can any one explain their accuracy and also provide PCB layout design which can i print on a blank PCB. also suggest is this circuit is good or not. your appreciation will be highly obliged.

It depends on stablizer design. If the designer has implemented under/overvoltage, the stabilizer will simply turn off the output power. If the stabilizer doesnt have undervoltage protection then if the input voltage decrease below 160V the output voltage will decrease below 200V proportionaly, till the control circuit is able to engerize (...)
Hi All, I want to ask a question. I am confused about it. I made a low power application circuit that work with thermocouple with rectifier at the beginning then the booster and then the voltage stabilizer IC to make the output constant at 2.7. The 2.7V drive micro-controller. Now at 2.7 Volt I have to check the power of the (...)
uit for 70W HPS but I must only change the stabilizer. Dear damiandoles Hi What do you mean by that ? ( stabilizer ) in that circuit ? I read on the Internet, that I can use ballast for fluresent lamps for HPS lamps less than 100W. Is it true ? I didn't hear it ever . can you attach the source that you are referr
Presented device is a 40 RGB diodes driver. The construction is quite simple, there are few elements on the board: stabilizer LM7805 + heat sink + voltage filtering capacitors microcontroller Atmega8 ULN2803
hi... i have made voltage stabilizer and circuit is successfully tested on vero board many times... but when i try the same circuit on pcb it started giving abnormal behavior... sometimes it works fine and sometime not ok.. even if i plucked pic off and then again put it on socket it stops working accordingly... can sumbody help me out.. thanks
To protect your stabilizer and its supply wiring you need an MCB at the source end rated at 10kva/phase current +10%. On the output side, the same argument, if its feeding a single 10kva load then 100A would do. If its feeding multiple circuits then each circuit should have an MCB rated for each one and its individual cabling. Frank
I need information about the taping of a tap changing voltage stabilizer transformer. I mean, for better regulation. I've done a rough calculation for the transformer. tapping is selected as: 180, 200, 220, 240, 260. and common.
Hi, Prabrahim I suppose it is necessary to add 12V integral stabilizer of the voltage after diode bridge and filterring capacitor C4 must be not electrolytic
i need static voltage stabilizer 1 KVA to 10 KVA , 90 V TO 290V /hex code /circuit diagram .contact me soon .
Your circuit works like a stabilizer with an output voltage (appr.) 6.8 + 0.7 v. Use a bistabil control element to make a permanent cut off.
hi for AC Motor it is normal motor which will use in servo stabilizer
please explain auto stab.the output of constant voltage transformer is 140v. scr fullwave ac switch with snubber circuit in series with 30v cvt output connected across 140v cvt o/p. a inductor(20mh) and capacitor(90 ? farad 550v) in series connected across 140 cvt o/p. scrs are triggered by pulse trans former. the o/p of cvt 140 fed through anoth

Hi. This is the stabilizer circuit Step up 110V AC to 230V AC from " have anyone the PCB of that circuit, and tested it by practically or on Computer simulation. I try it to simulate in Multisim 10 but no success. the "Orcad Design File" is also included with this attachment. Can
The name of the circuit that could help you is: “VFO stabilizer”. This is not a PLL, is just a cheap idea, to stabilize the frequency of a variable frequency oscillator (invented by radio amateurs back in 70’s). The signal from a stable on-board crystal oscillator and a sampling of the signal from the VFO are both processed thr

Hi Im looking for a practical 20kva 3 phase ups circuit and also a stabilizer for it,please help me with the job,thanks regards.
hai, i want a circuit for automatic 3 phase voltage stabilizer using triac plz help me Thanks and Regards Grittin James
Using a classical linear stabilizer circuit won't help you. The 7805 voltage regulator dissipates a lot heat. Try to use a DC-DC step-down convertor instead. See for example LM2575, LM2576, LM2596, LM2678, LM2679. Some details here
Thanks big! I for a long time searched for this circuit. The stabilizer of a power unit has broken down, the target transistor is punched, works, but there is an awful rumble (background).
It is supposed to be a dutycycle stabilizer related schemetic. Any suggesting??? Thanks a lot.
Could anyone please furnish me with the circuit schematic for a Qlink automatic voltage stabilizer.
It is dificult to propose current limiting circuit for your stabilizer because the addition should be compatible with your circuit. If you want any reasonable suggestion it is neccessary to post circuit I believe.
