Put a seprate transformer. It will solve this issue

Answer . depends on how low incoming ppower is unit will have min max allowable voltage on name plate but the lower the voltage the higher the amperage draw which can red…uce life of compressor or even kill it
Answer . because it reduces the power dissipation
The usual voltages produced by the power supply in a standard personal computer system are 5 volts and 12 volts. For more information see the Related Link shown below.
The power supply in a PC is a complex device using switch mode circuitry and transformers to generate +and- 12v, for modems and communications ports. +and-5volts for the logic… circuitry,3volts for the processor. All these supplies are generated and electronically regulated. It is such a waste when they are thrown a way still working. They are mini masterpieces of electronic engineering and are capable of starting a car!
low voltage problem may arise due to unbalancing of distribution transformer in your area. please ask your electricity provider to balance load on distribution transformer.
the voltage less than the required voltage to work a device or circuit is ment to be low voltage. For example if a bulb needs 10v to work properly, if we give only 6v the bulb… glows but it glows dim which means that proper voltage is not supplied. hope u got the answer............ According to the 17th edition regs in the uk. It is anything under 1000 volts
A: ABSOLUTELY and it works both ways hi to low or low to hi voltage . however there are some efficiency losses due to components losses. A 1 WATT source will never deliver a 1… watt to the load.
Yes, but it won't be pretty.
Lowering voltage will lower power consumption, but there will come a point where the desired operation of the device will not be met. For example if you had a variable voltag…e like a dimmer on a light bulb, you can reduce the voltage to a point where the bulb no longer emits a useful amount of light.
The low voltage range is upto 650V.
Autotransformers are absolutely safe when supplying a lower voltage load from a higher voltage source, and are used to do so. However, they do not provide isolation. If isolat…ion is considered essential, then autotransformers are not appropriate.
The step up transformer is used to change the voltage from high to low or low to high voltage by eitherincreasing the number of inding or reducing the number of winding in the… transformer,thus when the winding reduced on side of primary winding and ingreasing number of winding on secondary side it means the transformer should be step up transfo0rmer,and when the you increase number of turnsin primary side and reduce turned on secondary sidde the transformer said to be step down transformer
How does the 4-wire three-phase low votage consumer supply can be used to provide two different voltages?
It can but it's probably dangerous and probaly illegal. Answer It's quite normal to have two different voltages with a three-phase, four-wire, a.c. supply, and it's cer…tainly not illegal nor is it dangerous. For example, in Europe, a three-phase, four-wire, system provides 400 V between lines (line voltage) and 230 V between any line and neutral (phase voltage). While three-phase supplies to residences are unusual, in some countries (e.g. Cyprus) it seems to be standard. Safety: Three-phase supplies with a 230 V phase voltage undoubtedly have a 400 V line voltage. However for home electrics it will be dangerous and probably illegal to attempt to acces the live conductors in adjacent properties with different single-phase supplies in order to obtain a supply at the line voltage. The reply has to take readers' safety into account ;)
Low voltage is usually DC off a 120transformert Answer According to BS 7671:2008, Requirements for Electrical Installations , high voltage is defined as exceeding 100…0 V (a.c.) line-to-line, or 600 V (a.c.) line-to-neutral.
Voltage levels are defined by the electrical regulations in the country in which you live. In some countries, 'medium voltage' is not defined at all. For example, BS7671:2008… Requirements for Electrical Installations , the UK's wiring regulations define voltage levels as ' extra-low ', ' low ', and ' high ' -no mention at all of 'medium voltage'. According to BS7671:2008, 'extra-low voltage' is defined as 'that not exceeding 50 V rms'; 'low voltage' is defined as that 'exceeding extra-low voltage but not exceeding 1000 V rms'; 'high voltage' is defined as 'normally exceeding low voltage. Different values are given for d.c. voltages.
The difference is the magnitude of the potential difference betweenthe same two reference points. The magnitude is greater in thesecond case than it is in the first case.
