voltage regulater for philippines

[imagine]

iv seen some voltage regulaters in robinsons mall, in their handyman store,

now im not sure what it is i should be buying,
it looks like a transformer or battery charger,
2 voltage meters at the front, at the rear is 3 times 260 volt sockets for multy connection uk phil ect, plus 1 socket for 110 volts, the unit has a 2 pin plug to plug into a 2 pin socket from the main supply,

there are different models and prices depending on how many watts output,

can anyone advise which would be best to buy,

i take it that the more the watts output the more appliances can be run at the same time,
like,, washing machine, refridgerater,,computer ect

Not sure why you would need a voltage regulator as surely the supply voltage is within certain limits?

Or are you trying to feed appliances from a battery source?...in which case its an inverter that takes 12 or 24v DC supply and produces 230/240v AC from it but this will be at quite a low current so the number of appliances you can run will be limited. The output will be specified in Watts or VA (voltamps).

Alternatively, are you talking about a petrol or deisel engine driven alternator or generator that has no battery input just has an AC output(in the case of an alternator) or DC output if its a generator. If you are wanting to power household appliances then you need an alternator, the output of which will be regulated to give a constant voltage.

Hope this helps a little but i need more information on what your trying to do and what you think these "regulators" on sale in Robinsons claim to do.

I bought a 2000 Watt voltage regulator for our electric jackhammer as a bad power supply screwed up our first one.. The regulator gives a steady 220 volts and cuts the power with power surge/drops.
Pretty sure you can get much larger one than mine to run the whole house if you wanted..

Here`s the one I got.. Think it cost me 2,500??

Just a guide, you need about 1500 watts for aircon. 1000 watts will run a chest freezer and a ref and 500 watts for computer. Bad voltage will destroy all your electrical items. New tv often have them built in but you need to check.

Lordna , it is domestic mains im meaning,

thanks fred, 1500 w , is about 4000 peso,
20,000 is just over 6000 peso

thanks jonnijon

hearing about electric spikes, black outs ect, that when mains power returns on it can overload the appliances, some time ago I read somewhere in this forum I cant find the thread now, but there was talk of spikes and voltage regulators, so I thought this was a good way to protect valuable appliances, such as computer/tv/ fridge/auto washing machine, I want to buy an automatic washing machine here, but was worried if problems with regular blackouts might break it,
appreciate advise

To be honest we have had no problems with any appliance so far in 7 years Except an LCD TV that blew its power supply card during a nasty thunder storm.
The regulator I bought cost not much more than 2,500 (from memory) and that is used only to protect a 50,000 Peso AEG jack hammer.

Current destroyed my aircon and chest freezer, when the electrician called there was only 180 volts on the line

I was thinking over this,
I have extension leads that are fused and with surge protection,

would surge protection be more the thing I need rather than a regulator,
and much cheaper

Voltage Regulators

• Voltage regulators are deviced used to provide a constant voltage to any connected electrical devices. If the voltage given to an electrical device is too high or too low, it could cause damage. Voltage regulators help prevent this, adjusting the provided voltage up or down to keep it at the correct levels.
  
  

Surge Protectors

• Surge protectors, also known as surge suppressors, are a device used to protect against electrical surges. Electrical surges can have many causes, such as lightning strikes or faulty wiring, and can severely damage electrical devices connected to the power grid. When a surge is detected, a surge protector diverts the surge to the ground, preventing it from reaching the connected devices.
  
  
  Usage
  
  • Surge protectors are normally used with expensive electronic devices, such as computers or televisions. Since electric surges can happen almost anywhere under the right conditions, surge protectors are usually considered an easy and cheap investment.
    Voltage regulators are not used as often as surge protectors, but can be useful in certain situations. Some households or business may receive so called "dirty power," where the power fluctuates frequently. Voltage regulators can be used in such situations to even out the power supply and help protect electrical devices.

I need a constant 220 supply for my jack hammer which I dont think a surge protector can give me .. When the job is finished I`ll use it in the house to clean up our supply and protect my TV and ref etc..

thanks fred,

looks like a surge protector is no use at all as there is no earth to ground the surge

Surge protectors do need to be grounded, even when the connected equipment is double insulated.

What equipment are you trying to protect Stewart?

I am going to buy an automatic washing machine, so mainly to protect this, then possibly lap top / fridge freezer/tv

You must have VR or it wont be automatic for long
