What happens if you supply a 60 Hz ballast with 50 Hz power supply?

I first asked the question. I was told by an electrical engineer that the appliances would breakdown after between 1 day and 2 weeks use and he advised me to sell and buy new appliances in the Philippines. I was not able to obtain a reasonable price for selling second hand appliances and also found that appliances in the Philippines were very expensive compared to Malaysia. I was also told in the Philippines that the appliances would work satisfactorily . So I installed all the appliances and after 3 months they work OK except the clock which gains about 3 hours per day.My appliances include 2 refridgerators. 2 wine coolers, freezer.4 TV's,washing machine ,dryer,dishwasher,computer,fax ,etc. David dlw@tm.net.my

∙ 13y agoA: the ballast will saturate and probably heat up and finally blow up.
B. Well, yes, the ballast could saturate if the increased current draw from the 50 Hertz was high enough to make the ballast magnetic core ineffective.
In saturation the magnetic core no longer works properly to maintain inductive reactance and to limit current and then the ballast - and load - can overheat.
It also depends upon the type of ballast. A purely inductive ballast run at a lower frequency than designed, - assuming the load is a lamp or welder, for example, - will pass more current to the load.
If the ballast is a tuned capacitor-inductor combination that is frequency dependent, which is a less common arrangement, the ballast will then be away from the design frequency and pass less current to the load and run cooler.

∙ 11y agoThat depends on the device. If there is a transformer which has been designed for 50Hz, and you are supplying it with 60Hz, there could be a problem.
If the device uses the 50Hz for internal timing, there would definitely be a problem, but if the device uses bridge rectifiers and internal regulators and has no Transformers connected to the line voltage, using 50Hz or 60Hz wouldn't make much difference.
The problem is, you need to have a little knowledge about electronics before you could make that determination.

What is the power dissipation for TTL?
power dissipation of a logic circuit is usually defined as the supply power required for the gate to operate with a 50% duty cycle at a specific frequency.
If a load takes 50 kW at a power factor of 0.5 lagging Calculate the apparent power and reactive power?
If a load takes 50 kW at a power factor of 0.5 lagging calculate the apparent power and reactive power Answer: Apparent power = Active power / Power Factor In this case, Active power = 50 kW and power factor = 0.5 So Apparent power = 50/0.5 = 100 KVA
What determines leading or lagging power factor?
underdampedAnswerA lagging power factor describes a situation in which the load current is lagging the supply voltage. This describes an inductive load, such as a motor, etc.
Can you use a 60Hz variac in a 50 Hz outlet?
Yes, you can use a 60Hz variac in a 50 Hz outlet. However, since the frequency is less, the current and power dissipation will be greater, making the efficiency less. It will not carry its rated load.
How to perform SMPS with circute diagram?
A switched-mode power supply (switching-mode power supply, SMPS, or simply switcher) is an electronic power supply that incorporates a switching regulator in order to be highly efficient in the conversion of electrical power. Like other types of power supplies, an SMPS transfers power from a source like the electrical power grid to a load (e.g., a personal computer) while converting voltage and current characteristics. An SMPS is usually employed to efficiently provide a regulated output voltage, typically at a level different from the input voltage.Unlike a linear power supply, the pass transistor of a switching mode supply switches very quickly (typically between 50 kHz and 1 MHz) between full-on and full-off states, which minimizes wasted energy. Voltage regulation is provided by varying the ratio of on to off time. In contrast, a linear power supply must dissipate the excess voltage to regulate the output. This higher efficiency is the chief advantage of a switch-mode power supply.Switching regulators are used as replacements for the linear regulators when higher efficiency, smaller size or lighter weight are required. They are, however, more complicated, their switching currents can cause electrical noise problems if not carefully suppressed, and simple designs may have a poor power factor.
What happens to a 220v 50hz stereo amplifier when connected to a 220v 60hz supply?
Nothing happens. The stereo has a transformer that converts the power to DC, and 50 or 60 Hz input makes no difference.
What are the release dates for 50 Cent The Money and the Power - 2008 Move from Demand to Supply 1-8?
50 Cent The Money and the Power - 2008 Move from Demand to Supply 1-8 was released on: USA: 2 January 2009
Is there any difference in the consumption of electricity by using two sizes of power supply for example a 350watt power supply and a 480watt power supply with all else being the same on the comp?
The computer will only consume what power it needs. No diffference. if you have a 350watt power supply, and it is using more then 70% power consuption, the life of that power supply will be short, so always aim big when picking out a power supply, ie: 50-100 watts more than what you would actually need.
Can you run a 50 watt halide bulb on a 100 watt halide ballast?
Yes.
Types of AC-DC power supply?
Answer for countries in Europe and other world areas running a 50 Hz supply service.AC power supply is 230 v supply used in our homes for switching on fans, bulbs etc. where as DC power supply is used for switching on our laptops, charging our mobiles phones, i pods etc.

What is power rating for power supply of a toshiba satellite L305?
This is not a desktop computer and does not have a PSU, power supply unit. AC Adapter75W (19V 3.95A) Auto-sensing, 100-240V / 50-60Hz inputBatteryLi-Ion (4000mAh, 6-Cell)
How do you replace a computer fuse?
The only fuse located in a computer is the one in the power supply. It can be very dangerous to open a power supply without proper training. If you do not have the requisite training to repair a power supply, please do not attempt to open it. Your life isn't worth losing over a $50 hunk of metal and wires.
What happens when a 120 volt Wii is plugged into 110 volt socket?
If the power supply is 60 Hz AC, and the Wii says 60 Hz, there is no problem. The built-in transformer provides DC power to the electronics. Do not try to use a Wii designed for a 50 Hz system at a higher voltage.
What is the power voltage in Indonesia?
Since 1998, the standard mains supply throughout Indonesia is 230 volts, 50 Hz.
Will a 50 hertz digital piano work on 60 hertz power supply?
It should be all right. The main thing to get right is the supply voltage, because usually 50 Hz goes with 220-240 v and 60 Hz goes with 120 v.
What kind of power does a power supply receive from a wall outlet?
Household electricity is supplied to a pc's power supply module as alternating current (ac).The power supply converts it into direct current (dc) at various voltages - such as +12V , +5V, etc. - which are then delivered to the pc's subsystems.Some power supplies operate on 120 volts 60 Hz ac but others operate on 230 volts 50 Hz ac.Which voltage your power supply uses depends on which country you are in.For more information see the answers to the Related Questions shown below.
