Since you are based in Dubai, if I am not mistaken there the voltage is very stable. Assuming you need one in India.
You may need to decide whether you need a servo or a static stabilizer. Static stabilizers are silent, with faster voltage correction and much more expensive. Servo stabs will beep while correcting voltage and will remain silent when there are no fluctuations. Servo stabs may need servicing after many years since they have moving parts.
Static stabs have no moving parts hence easier to maintain.
Pls do look out for their service in your region.

In India for the Static category, you have brands like vertex and NKB Technocrats. I am sure there are other brands which other fm's may be using & can guide you better.

Regarding ups, I am familiar with APC but you may need to check on the specific one required for your purpose.

Hi Nitin,

Thanks for the response yes it’s for India.

Planning to go for Krykard and APC.

Most welcome Sunil. I have earlier used a 3 Kva servo Krykard and it was good barring the noise only during voltage correction. The intermittent noise is bearable and not a deal breaker. Plus Krykard has a good pan India service network.
Pls note that you may need to attach an extension board with many sockets to the Krykard stab since it had only 1 output.
From that point of view Vertex has 4 sockets behind. Pls do check the thread on these which has the pics of the rear side.
The main wall socket for the stabilizer has to be 16 amps.

Unfortunately, the New Arcam AV-41 was installed last 1 month back, and due to the high voltage one of the HDMI port not working, the video keeps on flickering. when I used 2nd Video out HDMI, it seemed to work perfectly fine. I am not sure, have to check with the Arcam supplier if this is covered under warranty to replace the port.

Was the power to the Arcam via the stabilizer when it happened ?
Hdmi ports are very finicky. Even while plugging in or removing Hdmi cables, ideally the power should be off.

Yes, all protection was connected. MCB > ELCB > Stabilizer > Furman M10X> Arcam, Amps and Projector connected through Furman. this was happened on 9th Nov. when high voltage blew the Stabilizer. I am not in India, when my son checked last week identified an HDMI issue. I have raised this with the supplier they are going to log this to Arcam to have a visit and have this checked and fixed. Yes devices were on when this happened.

In Mumbai the voltage does go up on an average to 245 V and sometimes to even 252V on the Adani line.
It may be prudent to keep a tab on high it goes and accordingly take professional advise if the voltage is too high.

Any of our tech savvy FMs have any thoughts on the utility of these stabilizer units ? Would they be any good ?
