TYPES
OF UNITS
Natural Air Cooled or Oil cooled, Indoor or Outdoor,
Wall mounted or Base mounted.
CLIMATIC CONDITIONS
Units are designed to work under severe environmental
conditions with temperature range up to 55 C ambient
& protection class
upto IP65.
TRANSFORMER
All transformers are designed to give low losses
and high efficiencies. The core material is high
grade, high permeability, low loss CRGO silicon
steel. The coils are wound with high conductivity,
annealed, insulated electrolytic copper conductors.
The insulation material used is of high standard
to suit Class F grade. The Transformers manufactured
and tested as per IEC76, BS 171 standards.
RECTIFIERS
Rectifiers are based on international quality
diodes and Silicon Controlled Rectifiers. Rectifier
circuits have different circuit topology based
on customer need, specification and efficiency.
Single phase bridge is used up to 5KW output and
above that three phase bridge or hexa-phase with
inter phase transformer scheme is used for higher
efficiency .
Rectifiers are designed and tested as per IEC
146 standards.
ENCLOSURES
Air cooled
Enclosures are fabricated from CRCA MS sheet of
upto 2.5 mm / 12 SWG thickness. Special type of
enclosures made from stainless steel, aluminum
or glass reinforced polyester are also provided
as per customer specification. Polycarbonate window
is
provided for viewing meters and indications. Lockable
doors are provided in the front and back.
Oil cooled
Oil tanks are fabricated from CRCA MS sheet up
to 3.00mm/ 10 SWG thickness. Control cabinet is
fabricated from CRCA MS
sheet up 2.5mm/12 SWG thickness. Oil tank is provided
with oil filling inlet, oil drain, oil sight gauge
& silica gel breather.
Sunshades are provided as per customer specification.
