Voltage Stabilizer

Where are you located?

He's located in La La Land.

What do YOU think it means.

Come on now, what have we told you about performing a simple internet search and reading the manual.

Fix the loose connections.

It sounds as though you are in a country that has issues with the power grid. If so there is not much your going to do to improve the end product. I would offer this advise; pick up a generator unit that will supply the needed power at the voltage you need it, until the power company fixes their issues.

Dear Mr. coolyaar,

The answer is YES. When Input and Output Voltage Range is given along with WATTS, THE CAPACITY is 4.0 KW. It appears to me me that the voltage Stabilizer is 5.0 KVA.

My view is Input Voltage Range of 80 to 250 Volts appears to be very large.

If the supply isn't capable of supplying 4kW without voltage drop, then adding a voltage stabiliser isn't going to improve matters.

The issue is that the supply cables are undersized. Get onto the power supply company and have a commercially expletive moan.

both the answer from dhayanandhan and PWSlack are correct. if you ask about capacity of the voltage stabilizer, it is 4 kW which means you can have it loaded for 4000 watt but if your main power supply is less than 4 kW you can't have it loaded

Have the main supply lines checked by the power company, if the voltage drop occurs within your property, you're risking your house to a nasty fire, if it occurs outside, you're probably setting things up for a sudden meltdown of the power lines, which can lead to electrocution risk for pedestrians if it's located at the primary of the step-down transformer.

This is serius stuff, don't buy any stabilizer to "correct" this !!

Dear Mr. Yahlasit,

You have mentioned - a VALID and IMPORTANT Point, and Thank you for the same. I replied only from Tech. Point of view, but working aspect did not strike to my mind.

I have NOTED DOWN your Point.

Thanks,

DHAYANANDHAN.S

You are wellcome Dhayanandhan, what may come before safety ? common sense.

I really get the feeling that if you attach a voltage stabilizer to a 230 VAC power source that is dropping to 120V, whatever the reason for the voltage drop will become painfully and dangerously obvious. I think it would be a much better idea to fix the source of the problem.

Be careful.

Allthough the stabilizer is rated for 4KW you must determine if the rating is for continous or intermittent usage as dictated by the "duty cycle" rating.

For instance:

A maximum KW rating of 4KW at a 40% duty cycle usually means the 4KW would only be sustainable for 40% of 1 hour = 24 minutes.

The amount of KW sustainable after this point is dependent on the quality of the stabilizer components and usually decreases substantially.

A graph and/or table should be available from the manufacturer that illustrates all of the values and information you will need to know.

First thing to check is your neutral good, if its bad, voltage could flux from 40 to 200 V. It could be bad at wheatherhead from bird dodo or water damage inside meter or if basement damp in panel. device you are proposing to use is for single appliance and can not be used to install on buss for multiple as it has no neutral - CAUTION - . Some 230v appliances have 120v controls so could not be used.

The 4000 is amp/heat rating of stabilizer. With motor load and normal power-factor = 5 hp or it may operate a resistive heater with no power-factor up to 5000watts.

Yes 4000w is 4kw.

Yes, You can load it up to 4KW, but act as per duty rating.

The 4KW rating means any combination of volts x amps will total 4KW.

Before you buy a stabilizer, I recon you check your main service cable, terminations/connections at the entrance box, your fuse connections, metering connections, and the distribuiton board connections.

I have seen 160 volts instead of 230 at peak hours of consumption, but 120 is quite low. Looks like the distribution transformer is some kms away from you. Give an application signed by many, to the concerned authority for installing a transformer nearby.

Domestic single phase of servo voltage stabilizer is available in standard fluctuation range of + 20%. All models can be factory preset for any output voltage from 215 to 240V P-N. standard protections include overload & short-circuit protection.
