I am Ram Dwiwedi from Allahabad. I am running a cyber café and small publishing company. I my area I am facing problem like regular power cut and voltage fluctuations and as you know voltage fluctuation is very harmful for many hardwires, so I want to buy those types of UPS system whose can provide solutions for these problems.
Than I got to know about luminous online UPS system. According to its brochure I thought I should try with this product. I bought 2KVA that is perhaps 1400 watts Online UPS systems. After two or three moths I knew that it is really workable product and it is good for other hardware also. It is not a very unique product just a general and very user friendly product.
Its double conversion online topology and high frequency PWM technology is new things but other feature is so so. But I am very satisfied by this product. And I can say It is justifying its costs. So I can recommend this product to other people also. I think luminous is not a bad company in service also because when ever I wan called there people they had come very promptly and now they are starting there toll free help line also. But I have some advice for luminous they should be more prompt on their servicing.
