Those look like their Industrial Servo's.
They used to have servo's for residential use as also specialized servo's for audio equipment with RF and EMI filters listed on their website. Looks like they have redone their websites. I also found another of their websites https://www.vertexpower.co.in/ which lists single phase servo's such as this one https://www.vertexpower.co.in/single-phase-servo-stabilizer.html.
You can call and talk to them, they are very responsive and will advise as appropriate. I am not sure whether their network is strong in the North so check with them. There were a couple of recommendations for servo manufacturers in the North on the forum. Maybe someone else will pitch in if they remember or you could see if a search brings up the post.
