Will a 6V 1.8A power supply harm equipment designed for 6V 600-1000 MA?
No. The rating on the power supply means: "This power supply maintains 6 volts between its terminals, and will supply whatever current is required by the device it powers, as long as that current doesn't exceed 1.8A for very long."
Since the equipment is only expected to need 600-1000 mA (that's 0.6 to 1 A), that power supply will support it nicely, and neither the power supply nor the equipment will damage the other.
Because equipment operating on DC is usually low-power electronic equipment, and it uses a power-supply to convert the house AC supply to DC at the right voltage. Most appliances needing high power are designed to run on AC because that is the normal supply to houses.
It depends on the equipment. A switching power supply as used for computers and phones and most equipment requiring a power supply usually will tolerate a wide range of frequency inputs and will work well. A clock designed to keep time at 60 Hertz will run slow. For a motor or a transformer, the higher frequency of 60 Hertz will cause a higher inductive reactance and less power will flow in that circuit. If the… Read More
the transformers are used to step down the supply voltage:) power supply kit is mostly used for electronic equipment... electronic equipment operate in low volatge, for that purpose we using transformers in the power supply:) with regards sakthivel lect/EEE
Power supply units are rated based on their output and efficiency. When more equipment is connected, a higher output power supply is needed.
A UPS is an abbreviation for an "Uninterruptible Power Supply". The purpose of this device is to provide power when the main power source fails. UPS battery backups are used to provide power for computers, data centers and various other types of equipment. Typically the back-up is used with equipment that cannot have a disruption in the power supply, or equipment which may be damaged if there is a disruption in the power supply.
Information Technology Equipment
An uninterruptable power supply (UPS) - is designed to keep a computer (or other equipment) running in the event of the mains supply failing. They're used in places such as police control rooms, hospitals, air-traffic control centres etc.
Most often, power supplies for any type of equipment is givin to you when you buy what the power supply is for.
It supplies electric power to any equipment that requires DC power.
You can't plug Hz into a socket outlet. What you get from an outlet is a supply of electrical power with a fixed voltage, a fixed frequency (50 or 60 Hz depending on the country) and a maximum allowed current. The equipment plugged in must be designed to operate at the same voltage as the supply voltage. With some equipment it doesn't matter if it's 50 or 60 Hz, with other equipment it does matter… Read More
Transformer Power Supply
Everything would work as designed if you used a 2 amp power supply for a 200 ma circuit. It's important to not go OVER the designed capacity of the power supply, and in fact, it's a good idea to make sure the power supply has at least double the capacity of the load current.
no no no no no no no no no no no
because the termination and relays in side the telecoms penal needs for DC supply to continues the protection equipment and relay and purpose of telecoms
An uninterruptable power supply is a power device for a computer (or other things) which is designed never to lose power in the middle of crucial operations. For example, if you're running a computer which is in charge of a critical process and there is a disruption in the power coming into the computer, the uninterruptable PSU (power supply unit) is designed to make sure the computer doesn't stop the process it was working on… Read More
A power supply that is designed to be outside the case of the computer. Most laptop computers use an external power supply rather than an internal one to reduce size and weight while the laptop runs on battery power.
To give steady voltages at the levels the equipment requires.
Can an inverter machine with 400 volts 3 phase 50 hz input power be plugged in a 460 volts 3 phase 60 hz input power supply?
The machine will be designed for a range of voltages which might include 400 v and 460 v but it depends on each individual piece of equipment. You should be able to read the voltage range on the piece of equipment.
The NLX motherboard uses an ATX power supply as the form factor was designed just for the motherboard
Not without using a step down transformer. Applying 240 volts directly to any 120 volt rated device is not wise. The manufacturer of equipment states on the manufacturer's label what the correct voltage that is to be applied, to make the equipment operate as it is designed to do.
The power supplied by a three-phase supply, or any supply come to that, is determined by the LOAD, and not by the supply. So you must look at the data provided on the equipment's nameplate to find out what its power rating is.
A: A power supply when designed it will have some nominal criteria and also some maximum output power available which reflect to the peak load that it can stand without burning up
When sizing power sources, you must match voltage (which you have done) and make sure the supply can supply enough current to the electronics. If your supply is the 800mA, and the equipment using this needs 2500mA, then the power supply is undersized. If the supply is the 2500mA and the user is 800mA, then your power supply is oversized, and will work just fine.
An ATX power supply is a power supply designed for ATX and microATX motherboards. It has a single connector to the motherboard with 20 or 24 pins. Unlike older power supplies, ATX power supplies typically do not have switches. A button connected to the motherboard and placed on the front of the computer tower is deperessed momentarily to signal the supply to activate. The power supply can also be shut off by the motherboard.
Yes. The voltage is the same on each. The ma rating of the power supply is the current the supply can handle before burning up. So if your appliance is designed to work on an 800ma supply, an 850ma supply will do fine.
If the appliance is designed to operate on only 220 - 240 volts, then it won't work on a 110V supply. However, most modern electronic equipment will operate on 100V - 260V, particularly laptops and cell phone power supplies, allowing it to be used on virtually any mains supply worldwide. Check the information label on the equipment and read the voltage requirements before making any connections.
The same as any surge arrestor equipment - to prevent surges from damaging the (telecom) equipment.
i have a question? in the earthing system should we connect the negative pole of supply to the earth for example a +24 power supply?
A DC Power Cord should, in practice, never overheat. If it does, there is something very wrong. A piece of equipment is designed to draw a certain amount of current, the power supply, cord and connectors are all manufactured to withstand a little in excess of this amount and, if too much current presents, then a fuse or other safety device should break the circuit. Power cords for domestic equipment should really NEVER get hot… Read More
If you are talking about a 200 mA supply source and the device that it is feeding only uses 150 mA then the answer is no. There is still 50 mA surplus before the supply becomes overloaded. Now if its the other way around and you try connect a 250 mA device to a 200 mA supply then you will have a problem. The voltage will start to drop off and the power supply will… Read More
It supplies thermal energy which can then be used by fairly conventional power producing equipment
If the power supply has blown what are chances that it has taken out the motherboard or something else?
Very unlikely. When a power supply "blows", a fuse is destroyed in the power supply. This is what the fuse was designed for. When a high voltage comes through, the fuse will burn out to prevent the surge from reaching the rest of the electronics. A surge protector does the same thing, but is better at catching voltage spikes than the power supply.
It depends on where the power source is needed. In portable equipment for starting engines or portable equipment like cordless saws, drills, or lights a battery is the preferred method of power. In indoor stationary charging equipment for portable phones for example a continuous supply of AC power being converted to DC is more convenient than have batteries around the home that have to be charged when running low on voltage.
The equipments power requirements, and the mains voltage. The output of the power supply must be able to deliver the correct voltage to the equipment, at the appropriate wattage. Additionally, it should be capable of operating on the supplied mains voltage and wattage.
On-line: The power from your primary supply typically is charging batteries that are then supplying DC voltage that is converted to AC to power your equipment. Hence if the primary power is removed the battery continues to power the equipment with no lapse. Off-line: Requires some type of switch over when a power outage is detected. It could be a switch over to a battery supplied power source that had been charging from the primary… Read More
UPS is Uninterruptable Power Supply. It is a battery-backup designed to keep the computers running in case of a power failure.
If 3 phase 240 is used to power a piece of equipment that should be powered by 1 phase 240 will it damage the equipment?
As only one phase of a 3-phase supply can ever be properly connected to a piece of 1-phase equipment, such as a motor or whatever, no damage will result if that connection is done correctly. As most household 1-phase ac power is derived from power generated and distributed as 3-phase power, this question may just be an exam question designed to catch out students who don't really know what they are talking about... For more… Read More
An un-interruptable power supply (UPS) - provides power to equipment if the mains supply fails. It allows (for example) computer-users to finish the work they're doing, and close down the computer properly.
because it provides direct current in home some equipment need alternating current so we can not use dc supply in home
The power takeoff on a Ford tractor is designed to operate equipment like plows, winches, and mowers. It uses the power of the engine to readily run accessories.
There is nothing to save. When the neutral wire becomes disconnected the equipment just stops operating. Disconnect the power supply, reconnect the neutral and the equipment will start operating again.
It would be possible if you have the proper testing equipment and electrical tools to do the job.
It's used to provide operating power for small devices that are designed to operate with a 9-volt small current power supply.
It "supplies the power" to whatever device you're referring to. Baffling, I know. Another answer: A power supply converts 120V or 240V AC power (sometimes called "wall", "line" or "mains" power) into various regulated DC voltages needed in a piece of electronic equipment. In a computer, for example, the power supply will typically provide +12V, +5V, +3.3V and -12V sources to the various components. Voltage regulators in the power supply help keep the voltages steady… Read More
Will a 110V 60Hz home theater system bought in the US work in Singapore which uses a 220V 50Hz by just using a voltage transformer?
Your stereo system has an internal transformer in the power supply that is designed to operate at a given frequency. If it is designed to operate at the load your stereo system will use at 50 Hz, then yes. Otherwise this transformer will overheat when connected at the wrong frequency, and will burn out. You might be lucky and the power supply may be labelled to operate at 50 or 60Hz; if not, I recommend… Read More
In general no, it might do some damage to both the equipment and the power supply. In certain specific cases it might be all right if you are able to measure the current to make sure it is 500 mA or less, and you can also ensure that the appliance can withstand 15 v.
The 0.8 Power Factor provided by generator manufacturers is not the load power factor, but it is the nominal power factor used to calculate the kW output of an engine to supply the power for a particular alternator kVA output. Alternators are therefore designed to supply their rated kVA at 0.8 lagging power factor.
The power supply to a given piece of equipment is governed by what the manufacturer requests, to make the equipment operational. By applying the wrong phasing or voltage will usually not allow the equipment to operate the way the manufacturer intended it to. Single phase systems has its uses in supplying services to homes whereas three phase systems are used in commercial and industrial services.
In theory yes, in practice - not always. It depends on the fine details of what kind of current your DC supply delivers, and how finicky the equipment you're trying to power is.
