hi to all my friends and bro.......,


Recently here in chennai the heavy lightening and thunder kicked a lot, one of my customers whole setup of audio sytems, Tvs, set top box (big tv and Tata sky, epabx, a new 6kva ups, wireles and wired lan modem , laptop, and many of the things were killed by this heavy lightening last week.

The new 6kva ups, epabx, laptop, lan modem and tata sky set top box all these were replaced by warrranty. and rest is not in warranty, it has to be serviced and replaced by himself.

But in future he dont want to fry his sytems like this, kindly suggest some protection unit for those sytems.

Other than a spike buster or a surge protector, there is nothing that can be done in such situations. The best to do is to unplug all such equipment from the mains and wait for the lightning and thunder to die.

Last year I lost a modem, and since then I always disconnect my equipment from the mains when I am not using them. I also do this when I am leaving town so that nothing untoward happens.

In your client's case I would have expected the UPS to protect the equipment from spikes and surges. But if it committed harakiri by itself, what else can be done?

Cheers

hey bro

same situation
i too lost modem when thunder and lighting happened last year :sad:

after that i too disconnect all my equipment when they are not in use and whenever again thunder or lightning happens i immideatly check all my house for my appliances to be unplugged

Hi

About surge protection !

I don't use any stabs , ! they are risky cause of relays! specially during surge.
I use Surge Suppressor, one I made myself, Be aware that the spike buster available in market (priced around 110 - 250) most don't have LC circuit, MOV in them, they only have capacitor and led.

Once there was short circuit in electric pole, then my house bulb , UPS , PC , Monitor whole thing smoked ! Except for TV, DVD Player , Music system, cause I had used this Spike circuit for TV, but did not check the spike buster I got for PC !! so my TV, DVD Player , Music system was saved !
Fortunately (as I use Branded PC) it had warranty, got PC Board, Monitor , changed.

See that Stab had in built spike buster. ! also better to use one along with it.

Genuine Spike will cost around 300 - 500 ! Electrical Brand Cona Has spike buster.

Hi,
Bought a V guard digital stabilizer for my 40" sony lcd yesterday....price is 2200rs(mrp printed was 2600rs)..max 2amps
Its mentioned in the manual that one can connect tv, home theatre and dvd player to the same(max 2amps) and 2 output plugs have also been provided. I have connected my tv, ps3,turntable and dvd player to the output of the same...Can i also connect my Onkyo receiver to the same? will it create any other problem? because i think ps3 consumes more power(the moment u switch on the ps3, tube light will just dim a little bit)....

RENJITH,
trivandrum.

 

[moserw]

TV, HT and DVDP should be fine. For anything more better to invest in another stabilizer IMHO.

definitely buy another stab

 

[skumar]

2 amps will give you ~400W, your 40" TV might consume ~250W and the DVDP ~20W. Based on the consumption of PS/3 and your turntable , you may connect one of them to TV+DVDP.

Go for a separate 5amp stab for your HT+Turntable/PS/3.

Thanks for the inputs venkat sir,

Dear Venkat sir, can you please give me some suggestions for some decent surge protectors to go for these products CRT tv, LCD tv, Home Theatre sytem, DVD Player, Projector, Set Top Box, Laptop, Security survilience Camera and also for Video conferencing system.

And also suggest me, If there is any particular UPS can be used for these products for safety measures and also in improvised sound and picture quality segment.

Thanks in advance.

Merely connecting the UPS may not provide adequate surge protection. What was the surge rating on the UPS? You would need many hundred Joules of surge rating to protect from lightnings (at least 800J, as suggested in avsforum). The more the merrier. If the UPS rating is not sufficient, a surge suppressor of appropriate rating is required.
Although disconnecting it from the mains is probably the best protection.

As I mentioned elsewhere, an UPS that can give you pure sinewave protection will be expensive. Am I right in assuming you are looking for your demo room? When power goes, so does you A/c, and there is not much point is showing a demo then.

Instead of a UPS look for a good servo stabiliser with built in surge and and spike protection. You can get one from Krykard or from Vertex. If you want really hight quality you should contact Audire. They make some super power conditioning equipment. But remember they are very specialised equipment meant for audiophiles and thus a expensive. If I remember right they are around 20K per Kva.

Another option if you lose power for long periods and you don't want to stop a demo is to a get a generator.

Cheers

 

[jeevabobby26]

Thanks for your valuable suggestion and reply venkat sir,


But, this is not for me or in my showroom setup, the suggestion is only for my customer, he needs it really and good decent servo stabiliser as sugested by you venkat sir.

In my showroom, i always switch off the mains of each devices and equipments, when not in use or when the demo is finished and i also suggest the same for my customers.

But, still the above mentioned customer who has problem affected by the thunder needs the protection for his entire systems.

thanks

well those of u who are buying the V-guard DIGITAL stabilizer for lcd/plasmas etc,i suggest u buy the model called VG crystal rather then the DIGI-50,100,200.
since the DIGI series can handle input voltage of 295v but gives a output voltage of 253v,most lcd and plasmas will only handle upto 240v to 250v as said in the rear of the tv or manual,while it can handle higher voltages i.e more then 250v ,neverthless the tv is taking a beating ,its like a slow poison so it will shorten the life of ur tv.
the VG crystal model can handle a input voltage of 290v which is 5 volts less then DIGI model,but it outputs only 240v that is 13v lower then DIGI models.


but those who have realy expensive tvs or other expensive electronic devices that require higher power,better to go for servo based ones.

those of u how have the V-guard digital series,does it have a voltage selection switch?.

here is another product from apc http://www.apc.com/resource/include/techspec_index.cfm?base_sku=LE1200I&tab=models

here is another product from apc Line-R 1200VA Automatic Voltage Regulator

Hi,

I have V-guard digi 100 And here is the extract from manual.

"The didgital electronic voltage stabilizer gives a regulated output of 220 +/- 7% for an in/p of 170v - 275v. In case of high voltage > 275 at the input, the o/p rises above 220 +/- 7% and when the i/p reaches 295v the stabilizer will be cut off automatically. In case of low voltage < 170v the o/p voltage will goes below 220 -7% and when the i/p reaches 140v the stabilizer will cut off automatically."

Also there is an o/p LED indicatior which when becomes red, it says that it is operating in high/low voltage range and you can switch of manually too.

I don't see it will reach 253v and even if so in a fraction of time the stabilizer will be cut off.

I compared Digi 100 with crystal. Digi 100 was very heavy compared to crystal and they said digi series has special winding and high VA rating and the transformer construction and winding wire is very good compared to crystal,.

Also v-guard mentions the digi series is suitable for equipments like LCD/Plasma TV, DVD, Home Theaters, Hi-Fi Music Systems, Medical equipments and Photostat Machines.

VG crystal price is 2k and for digi 100 i paid 2.2 k[sp road, blore]

Thanks,Prakash.

well i bought the crystal model,checked the voltage its about 218v output when the input was about 240.the DIGI 100 is heavier because of the higher capacity rating ,so more winding in the transformer,if u check the DIGI 200 its more then double the weight of DIGI 100 again due to the higher capacity of digi 200.
VG crystal is more suitable for tvs,since its doesn't output more then 240v which is the max operating voltage of most tvs,but the DIGI series high voltage cut off is at 253v output(when input is 295v) where as the VG crystal cuts of at 240v output(when input is 290v).
the low voltage the digi series will cut of when the input is 140v,where as the VG crystal cuts of when input is 120v.
so the VG crystal is better suited for tvs,since most tvs sold in india will operate from 110v to 240v.

220 + 7% is not 253V? Am i missing something.

I feel digi series is good for AVR.

I feel digi series is good for AVR.

well when the main voltage is 295v which is above the normal 230v,the DIGI series will Output 253v instead of the 295v input.if the input voltage is above 295v it will cut off,i.e will not output any voltage.

Here is the reply from V-Guard customer service. i wrote to them on behalf of our forum to get the clarification.

----------------------------------------------------------------------

Dear sir,
Thanks for the trust in V-GUARD, VG-CRYSTAL and DIGI -100 , both are digital stabilizers, their working and features are same.
The VG - CRYSTAL is having 2 Amps capacity, and DIGI -100 is having 3 Amps capacity, VG-CRYSTAL is specially made for LCD TV's having features like ,wall mountable,& having 6/16 Amps socket and 5 Amps 4 pin socket.
The DIGI -100 will give output -220V +/- 7%(from 170 V to 275V input)
Please note the input mentioned above is normal supply of KEB.
When input is 295 volt it is a abnormal situation, and it will be for only
fraction of seconds, When input is 295 v out put of DIGI -100 will be 252 v and it will cut off the output supply.

Any LCD TV will have the with standing capacity of fraction seconds of
variation in input. But if you require 240 v maximum at output, we can adjust the stabilizer working range.In that condition, high voltage cut-off will be at 283 vInput.

----------------------------------------------------------------------
Dear Sir,

I am Prakash from Bangalore. All the stabilizers in my home are from
V-guard and i have purchased the V-guard Digi 100 last month. I am very
happy with your products.

I would like to know the difference between V-Guard crystal and V-guard
Digi100.

Also people say that V-Guard digi 100 will Output 253V when the i/p is
295V. is it true? And looks like the LCD TV's will get affected when the
input voltage is more than 250v.

Hence for this reason people advise that V-Guard Digital series is not good
for LCD's whereas V-Guard advertises that this model is good for LCD's,
Plasmas, High end music systems etc.. Would be great if you can clarify us
on this. This will help us a lot of of forum members in purchasing your
stabilizers.

Kindly go through this link where your product is being discussed on the
above issue.

Appreciate an early reply.

Thanks,
Prakash.

prakasse unfortunately our KEB sucks with a huge variations in voltage,todays at around 2am the voltage was 320v,for a good 1/2 hr,the V-guards digital stabilizers itself will conk off anything above 320v.
with voltages like those i think i have to buy a servo stabilizer since then can tolarate much higher voltage and are more accurate.
