  Profile :-

Our Work Place : 

We have an industrial set up of around 2000 sq. ft. in Dombivli  (East), Dist. Thane, to carry out all production activities like inward quality control of purchased material, well maintained stores, where the material is stored according to its grade and quality. Quality control is exercised from the stage of procuring raw materials itself. Further on production bench, the material is processed by qualified and skilled technicians under the guidance of qualified Engineers. After that, the unit is tested at Test Bench for it's rigidity, performance and quality. Then this finished product is brought to dispatch department for packaging and forwarding.

Our Experience :

We are in this field of power electronics and control panels rightly from 1990s with the overall experience of 12 years. We have achieved great excellence in the power field for designing and execution of power control products. In addition to this, we are also providing consultancy services in the power electronics field to different organizations like MTNL, BSNL etc.

Production Range :

With the great experience in the field, we have wide range of products indifferent capacities i.e we manufacturer the Inverters from capacity of 0.1 KVA to 50 KVA (DC Source from Battery as well as from Solar Panels).

  Products :-
Inverters
Inverters
  • Longer and Continuous back up time : Back up time available from 20 minutes to
    several hours with increasing number of batteries.

  • Regulated Battery Charger-Low Running Cost. Ensures longer life of battery : We provide boost / float cum trickel charger which avoides the excess charging. Thereby avoiding boiling of battery water, which inturn saves electricity & reccuring maintaince of battery.

  • Latest Switching Technology-Higher Efficiency : The inverter controller is either open loop or close loop pulse width modulator with 6.8 kHz carrier frequency which gives us the higher efficiency.

  • Separate Transformers for Inverter and Charger - ensures longer life of Unit : We avoide using same transformer as inverter transformer & charger transformer.  We separately provide two different sections such as inverter section & charger section.  Inverter section mainly consist of switching circuit transformer & power device.  The charger section in either smps type or linear power supply type or thyristor controlled type depending upon the capacity & type of battery where the transformer is separate from that of inverter section.

  • Very Compact in Size : With great experience in this field & continuous research in the same field.  We always use new & latest technology by which we can always provide compact units to our customers.

  • By-pass Mode : This mode is provided on demand as to give additional facility to bypass the system from the main supply as and when required for maintaince purpose.

  • Front panel LED indication - mains ON, Inverter ON, Battery low & Overload : Mains on : Visual indication for mains supply.
    Inverter on : Visual indication when inverter is ON ( Mains Fail )
    Battery Low : Visual indication for battery low
    Overload : Visual indication when inverter is overloaded.

  • Overload protection : This facility is provided for protecting inverter from getting overloaded.  In this cases first unit will go on current limit mode & even if the overload persist it immediately trips off.

  • Dead short circuit protection : This is optional protection.

  • Input and Output protected by fuses : Provided to get protected form over current.
