What is the nominal supply voltage?
The term, 'nominal', simply means 'named'. For example, the nominal supply voltage for a residence in the UK is 230 V. But this doesn't mean that the actual supply voltage is 230 V, because the supply voltage is allowed to vary by -6% and +10% of the nominal voltage. In other words, the actual voltage could be anywhere within the range of 216.2 V to 253 V. In fact, during periods of heavy load, the actual voltage would tend towards the lower end of this range, whereas during periods of higher load, the actual voltage would vary towards the upper end.
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.
'Nominal' means 'named'. So a 'nominal' voltage is the named voltage of a system. For example, when we talk about a 120-V or 240-V system, we are describing their nominal valu…es, not their actual values which can change from moment to moment.
The word nominal means the lowest possible safe amount. So, nominalcurrent or nominal voltage is the lowest amount necessary toperform an electrical function like keeping a li…ght turned on. Answer The original answer is incorrect. ' Nominal ' simply means' named '. So a 'nominal voltage' is the 'named voltage', asopposed to an 'actual voltage'. For example, the nominal voltage ofresidential supplies in the UK is 230 V; however, this value isallowed to vary between +10/-6% of the nominal voltage. In otherwords, a nominal voltage of 230 V may vary between 216 V and 253 V.
It is a rated value
A zener diode has a voltage when it reachesbreak over it may be 5v 12v or other voltage as manufactured. The manufacture will produce a 5v zener or is it? This voltage can ch…ange from device to device but the mean or nominal voltage will be as close as 5v as possible. So when buying a 5v zener do not expect 5v absolute but a nominal 5 v . ZENERS are designed for a specific voltage [ THEREFORE NOMINAL] as mentioned above . depends on the voltage required it can be bought within a specific voltage -/+ a % of the breakdown
It is the rated voltage of an electric equipment. It is the voltage at which the device is designed to operate. Another Answer Nominal means 'named'. So a nominal volta…ge is the 'named' voltage. For example, the nominal voltage of the supply system in Britain is 230 V. But its actual value is allowed to vary between 216.2 V and 253.0 V.
Put a seprate transformer. It will solve this issue
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!
The rated voltage of a motor listed on the nameplate is called the terminal voltage. This indicates the actual voltage on the motors terminals at which at which the manufactur…er designed to operate. Whereas, Nominal voltage is the design or configuration voltage of the electricity distribution system.
The two outside contacts (of four contacts) are connected to the power supply in the computer.
Nominal voltage is the 'named' voltage -for example, the nominal supply voltage in the UK is 230 V. But this is not necessarily the actual voltage at a particular time. A n…ominal voltage is normally expressed together with the percentage by which it is permitted to vary from that stated value. For example, in the UK, the nominal voltage is expressed as: 230 V +10% / -6% --in other words it is allowed to vary between 216.2 and 253 V. The term, operating voltage , isn't actually defined anywhere, but is usually taken to mean the actual voltage supplied to a device at any particular instant, and this should always fall within the allowable range of the supply system's specified nominal voltage. The operating voltage can be found simply by measuring it with a voltmeter.
Depending on the power supply, +12, -12, +5, - 5 and ground. Some also use 3.3.
It convert 220v or 115 to -12v and +12v by using many components and step down transformer.
In theory, voltage should be the same around the clock. In practice you may get a tad higher voltage at nights, as there's less load on the system. With most people asleep, th…ere aren't as many machines running.
AC current to residences in North America is 110 volts at 60 hertz, but 220 V and 440 V are available for industries that need it.
