| 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).
Servo Controlled Voltage Stabilizers from capacity of 0.1 KVA to 300 KVA. H.V. Testers
upto 100KV. Control and Power Transformers upto 500 KVA. Isolation
Transformers upto 10 KVA, UPS from 0.2KVA to 50KVA. SMPS upto 3KVA,
Control Rectifier upto 100 KVA, DC Power Supplies upto 50 KVA as also Control
Panel of different capacities as well as different mode of controllers.
Market Sector:
We
are successfully marketing our products in Maharashtra State at Mumbai,
Pune, Nashik, Dahanu, Chiplun, Mahad, Sindhudurg District and Goa State.
We are also looking forward to extend our marketing area in the States
like Gujarat, Karnataka and Andhra Pradesh in the very near future. |

|
-
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.
